Food rules.

I’m all for flexibility when it comes to what people eat. Labels like ‘vegan’, ‘paleo’, ‘keto’ for a lot of people aren’t particularly useful (even when self-imposed) if that means the structure of their food intake is tied up into the ‘rules’ of that particular diet. People panic when they are out of their own food environment and unable to eat according to the rules of their dietary ethos. While there are those who intuitively know they don’t need to rigidly eat the same foods or meals to be able to progress towards their health goals, this isn’t a widely appreciated concept. For some, diet ‘rules’ can create a certain degree of neuroticism around food; people argue it is a form of orthorexia at its worse – I’m not sure I agree with that, given the complexities associated with diagnosed eating disorders. Regardless, if the anxiety around food exists, it can lead the person to turn down invitations where their dietary rules will not be able to be adhered to, thus becoming socially isolated from their normal circle of friends. Or they may still attend with the intention not to eat, only to ‘cave in’; one small snack becomes a bit of a binge-fest because they have ‘blown it all.’ Both of these situations can make a person feel pretty terrible, and do nothing for their self-esteem.  You can see why, then, there are people who are adamantly against ‘rules’ around food.

However, I don’t agree that there shouldn’t be any structure around what, how, and when a person eats.  I think you’ll know I’m not suggesting this structure should equate specifically to a dogmatic dietary regime, such as only eating ‘paleo’ or ‘raw vegan’. I’m talking about rules that take the decision making out of some pretty common every day food experiences. Let’s face it, most people have a lot going on in their lives – we make 35,000 decisions per day (apparently!), 200 of them are food-related, though we are conscious of about 12-15 of them. Many people don’t have the bandwidth to be directly  making decisions about what to eat day-in, day-out (hence food plans like mine are awesome, btw). That’s what makes it so easy to ‘succumb’ to takeaways at the end of the day (I say ‘succumb’ as I know many people think it’s lack of willpower. Well, no, it’s more decision fatigue than anything else). Dogma around diet is, after all, the appeal of following it – someone else has deemed what you can eat and what you can’t. This takes the thinking out of it and works perfectly fine… until it doesn’t. And it doesn’t take long for it to start causing more headaches than not. The type of rules, then, that I’m thinking about are those which are akin to brushing your teeth. You just do them, they are non-negotiable. Once you get into the habit of them, you don’t even have the think about it.

The types of rules I’m thinking about include:

  1. Never eat standing up (therefore omitting mindless snacking).
  2. Brush your teeth after dinner (to avoid snacking later in the evening).
  3. Have at least one serve of vegetables at breakfast, and 2-3 at lunch and dinner.*
  4. Put all junk food in the house in an opaque container and keep high up in the pantry, so they aren’t having to see it every time they open the cupboard to prepare meals (out of sight, out of mind).
  5. Choose a protein choice (meat, eggs, fish) and vegetables first when eating a meal out, and then (if still hungry), choose something else. This will fill you up, so there is less room for other foods that are easy to overeat.
  6. Order dressings and sauces on the side (so you can control how much you use).

Instead of feeling anxious about having to decide what to eat, then constantly second-guessing what to do, simple guidelines like these can help you make better decisions in any context. They take the thinking out of it, therefore less energy is wasted and they aren’t constantly ruminating about what to eat. This creates less anxiety and neuroticism, and people can feel empowered and confident in their food decisions.  It’s less about the availability of specific food choices and more about way food is eaten, the environment it is eaten in, and the type of food. You don’t need to be perfect to be awesome, you just need to be consistent, and consistently approaching food in the same way (not deciding that you’ve ‘blown it all, so you’ll binge’ whenever you make a choice not deemed ‘suitable’ as part of your dietary regime).

From clinical experience, I find most people respond well to strategies such as those mentioned above.

Does HIIT take a hit on a ketogenic diet?

Much of the research points to the utility of a keto diet for increasing fat oxidation for longer, slower training. After a period of adaptation, athletes are then able to tap into an alternative fuel source which affords them an extensive supply of fuel at a steady rate, unlike carbohydrate (glycogen) stores which are limited and easily depleted in a moderate-long training session. Thus, it stands to reason athletes are able to go for longer than if they are straight carb-burning athletes in an endurance event – something that Maunder and colleagues discuss in this most recent paper outlining the practical application of a low carbohydrate diet for athletes of varying abilities. However many of the recent randomized trials (such as this one here) have found that performance, particularly at the top-end of the spectrum, is compromised when athletes switch to a lower carbohydrate approach. Further, the relative effort at a given heart rate is increased. You go slower, but it feels harder. Ouch. This understandably makes an athlete’s coache a little nervous to recommend their athletes go on a lower carbohydrate diet.

Interesting though, this is not the experience of many people I work with who transition to a lower carb diet. If anything, performance improves for the athlete (something I’ve written a lot about over the last few years, including this blog here). Given enough time, any reduction in power that occurs early in the transition phase appears to be reversed and the athlete comes out leaner, stronger and fitter in their endurance training. Reducing reliance on carbohydrate as a training fuel reduces the oxidative damage that occurs during training, thus inflammation is reduced. They aren’t placing their body under as much oxidative stress and therefore the athlete can train more consistently during the season with less risk of stress-related injury and illness. This may also be due to a higher presence of beta hydroxybutyrate in the bloodstream, which act as signalling molecules and increase the transcription of enzymes that encode antioxidant genes superoxide dismutase, catalase 2 and glutathione peroxidase. This helps scavenge free radicals created through training and protects the athlete from tissue damage. This may be one of the reasons why they are seeing better results with their key races.

Two of my mates felt similarly, and experienced similar benefits of adhering to a low carbohydrate diet, experiencing no detriment to high intensity training, despite what the research deemed. So they decided to test the hypothesis.

They took 18 male endurance athletes who were habitually eating a standard western diet, and randomised them to consume either their normal diet (control group), or a very low carbohydrate ketogenic diet, consisting of no more than 50g carbs per day for four weeks, and performed graded exercise tests before and after the experiment, and a HIIT session (5x3min, work/rest 2:1, passive recovery, total time 34min) before, and after 2 and 4 weeks.

The researchers found that (as expected) fat oxidation levels increased in the experimental group throughout the tests, and total time to exhaustion, performance in the HIIT session and rate of perceived exertion was no different between the groups. Ergo, the ketogenic diet did not impact the athlete’s ability to undergo high intensity training (nor make it seem harder for them). Interestingly, the level of protein in the diet was around 29%, higher than the 17% used in other studies – this could account for the level of ketones present in the blood stream that were lower at the end of the study (0.4 mmol/L), just out of the ‘nutritional ketosis’ range. The difference this may have made to the athletes’ performance, however, we don’t really know.

Many of the studies conducted that have found performance is reduced are likely too short to allow the athletes to adapt to a ketogenic diet, which is thought to take several weeks to months. Hopefully this new research makes you think twice about taking the results of a study like such as the one here, as a reason to dismiss the low carbohydrate diet for athletes.

To recap, then, of what we know is possible for athletes following a lower carbohydrate approach:

As a side note, lots of peeps look at the elite athlete who chows down on carbohydrate in racing and during everyday life and thinks to themselves that, if they can perform to that standard eating a higher carb approach, then why can’t I? A couple of points to note:

  • The elite athlete may train from 20-30 hours per week – by default they spend a lot of time in a depleted state, meaning they are likely training low glycogen as it is impossible to replenish carbohydrate at the rate they are burning it. This is going to afford them the same capacity to train in the lower carb state that provides enhanced training adaptations. The average age grouper may have time to train 12-18h a week maximum, and don’t have the volume available to get into the low glycogen state.
  • They are elite for a reason. They are able to go harder and faster than most people –psychologically they are able to hurt more and potentially go longer before they bonk – we age-groupers have more of a preservation mindset. They may also be able to train harder when in an inflamed state for this reason. I’m not saying this is ideal (far from it). I’m just putting it out there as a reason why there are professionals who are able to see results where others don’t.
  • Even at the top of the field the elite athlete can suffer, and far more than an age-grouper. Years of a nutrient-poor, carbohydrate rich diet and overreaching to the point of overtraining will leave an athlete burnt out and unable to continue on at the level they previously enjoyed. It might appear that elite athletes are bullet proof but I’m sure as you’re reading this you’re thinking of someone who falls into this category. Things aren’t always as they appear, and the golden glow of success can be pretty fleeting.
  • Of course, there are others who are just awesome and continue to turn up and take it out year after year, regardless of diet, training methods, lifestyle etc. Like the people who drink every day, smoke like a chimney and don’t eat vegetables, yet live to 102 years.
  • Re: racing high carbohydrate – that Maunder paper again – worth a read.

Overcoming stumbling blocks on a ketogenic diet: a case study

I had a client contact me for an email consultation this week. She was frustrated as, despite following a ketogenic diet (where carbs are restricted to 30g or below, over 70% of calories should come from fat, and protein is moderated), she was unable to get into ketosis.

I had a look at her food diary and could quite quickly see where I thought she could change things to help enhance her ketogenic approach. With her blessing, she’s allowed me to share this with a wider audience. Like many things, if one person is having challenges finding the right balance in their diet, there are likely many more people doing very similar things and potentially experiencing the same frustrations.  I focused on some of the main issues I saw.

You’ll notice there are foods that don’t align with ketogenic diets OR would be included in any diet for someone wanting to shed fat. We (the client and I) spoke on that in general, as clearly she knows this (i.e. cheesecake). The points I focused on were those that can trip people up that she might not be aware of. I’ve screenshot her food diary, and then my comments are below.

Her diet:

​​​​​​

Major points – unable to get into ketosis despite sticking to under 30g carbohydrate per day. This is measured by a blood ketone meter, and she wondered if she needed to add more fat to do this. Her overall goal is weight loss.

The thing with weight loss and the ketogenic diet, if you follow the advice from Phinney and Volek, pioneers of the ketogenic diet space, part of the energy your body needs to consume should come from your own fat stores, and not be provided for by diet. It’s a common misconception, as I see many people embark on a ketogenic diet for fat loss purposes but the opposite occurs – they gain weight. A common strategy at this point is to further reduce carbohydrate intake and bump up the fat. However, this will often further exacerbate weight gain (and frustration around the approach). Worst case scenario here is when the frustration leads to ‘to hell with it’ and that low carb diet is supplemented with all manner of processed refined carb junk food because ‘what’s the point? I can’t do this anyway, I’m useless and it’s not working for me.’ Clearly the end result of this self-punishment is further fat gain, some horrible carb cravings and a bad psychological state. Needless to say, I don’t think adding in more fat is the answer in this instance (and for this client), however I do think that tweaking what she is already doing is going to help.

It’s also good to remember that blood ketones aren’t the be all and end all – these indicate ketones in your bloodstream but sometimes, when these are low, this just means we are using them for energy – which is what you want! This is more likely to be the case in an athlete rather than anyone who is generally just active. In this case example,  I think the diet is the main reason for her not being in ketosis, rather than that the client is using ketones efficiently. However,  it is worth remembering that if you are following a ketogenic diet and are not seeing the expected results on the blood ketone meter.

Finally (and something I mentioned to the client) you don’t need a ketogenic diet to successfully lose weight, and sometimes focusing instead on the pointers I give at the end, regardless of ketosis, will give the same end result. Something like my online menu planner and individualised nutrition coaching. However, I would recommend in that instance to up the protein (double the recommendation I give you) and drop back the fat intake, as people often find that far more satisfying and easier to adhere to – which ultimately is THE most important thing with any dietary approach.

Key issues I picked up:

  • Too much protein in one sitting/in general
  • Processed foods
  • Dairy
  • Unintentional free sugar

1.Milk –  both the sugar in a cup of milk and the protein (whey) will raise insulin levels, thus put you out of ketosis. This is true of skim and standard milk.

2. Protein cookies: the type of sweetener/fibre used to make it a lower carb item can also spike insulin. For some people it is definitely a dose response thing going on – they can eat ½ cookie no problem, but a whole one will kick them out of ketosis. For any items like these, and if you do have blood glucose or blood ketone meters, it can be good to get a reading after a certain dose to see what effect they have for you. At any rate, highly processed goods can still negatively impact on blood sugar and appetite regulation in the absence of them being carb-based.

3. Coconut water – contains 3g sugar per 100ml or thereabouts. Any amount of free sugar in the diet is going to impact pretty quickly on your blood sugar levels if you haven’t just finished exercising, and kick you out of ketosis. The types of carbs you want to be having in your diet are specifically non-starchy carbohydrates -the majority of any carb sources coming from green leafy vegetables, other colour vegetables, perhaps some pumpkin/carrot depending on their effects on your blood sugar.

4. Grapes: any fruit is going to impact on your blood sugar levels, and particularly grapes – even if you stick within your limit of carbohydrate, the sugar from these are going to hit your bloodstream pretty quickly and cause an insulin response, thereby lowering ketones, especially if eaten outside of a meal that contains fat and/or protein (both of which slow down the glucose from hitting the blood stream). Fruit is typically best avoided on a ketogenic diet, aside from lemons, grapefruit, some berries.

5. Protein content of meals: for most, these need to be lower unless an individual is athletic. If struggling with getting into ketosis, it can be good to lower protein consistently to 1g/kg ideal body weight. For this particular client, this is 65g per day. Many days are consistently above this. In addition, the amount of protein in any one meal makes a difference – ideally, not more than 30g protein in any one sitting and, for you, likely 20g in a meal. This is obviously going to differ from person to person – as mentioned, athletes who have a greater energy output can generally get away with more protein (and more carbohdyrate) compared to a person who is sedentary or just lightly active.

6. Timing of food: eating within a restricted window (and not eating later in the evening) can help a ketogenic diet – our liver’s ability to metabolise carbohydrate is dictated in part by a ciracadian rhythm;  we are naturally more carbohydrate sensitive in the AM, less so in the PM, so carbs are likely to spike insulin more in the evening. In addition, fasting naturally upregulates ketone production and can help accelerated ketosis. Further, snacking can (for some) keep them from being out of ketosis, so 3 meals, or 2 meals plus a snack is recommended.

Key recommendations:

1. Drop protein down in each of the meals so you are averaging approximately 20-25g at meals.

2. Time any foods that have a greater amount of carbohydrate in them for after exercise (ie lower sugar fruit, or nuts that have a higher carb count such as cashews). The body doesn’t need to rely on just the action of insulin to deliver carbohydrates to cells in this instance, as we have receptors called GLUT-4 receptors in our muscles and in adipose tissue that can take up carbohydate and are activated post-exercise. Remember, an increase in insulin suppresses the production of free fatty acids, the precursors to ketone bodies.

3. Engage in exercise to help upregulate ketone production – aerobic/weight training.

4. Fasting for 14h at a time to help body produce ketones. Now for women, fasting can be a great tool, but can also backfire (read more about that here). Generally speaking, the fasting approach can be something that is incorporated 1-2 x per week if fat loss is a goal, and on other days, opt for a 12h window between dinner one night and breakfast the next day. The most important thing, though, is to be aware of negative changes to energy, how you feel, mood and sleep patterns – all underlying signs of a stress response that you might not be able to cope with.

5. Focus on diet quality – so the carbs, protein, fats are coming from whole foods and not processed or snack foods – ie protein cookies, fat bombs etc

6. Remove drinks / foods that contain easily digested carbs even if they fall within the carb count for the day. You’ll feel far more satisfied (and it is far more nutritious) to get your carbohydrates from green leafy vegetables which also contains a good amount of fibre.

7. Dairy – stick to hard cheeses and forgo the softer cheese/milk.

These are just some pointers from this client’s diet; another practitioner may pick up others. I will reiterate my point, however, in that a ketogenic diet, when done purely for weight loss, isn’t always the best approach and, for alot of people, unsustainable and too much like hard work. If you’re struggling to get the balance right and not seeing the results, then there are definitely other alternatives out there – one which will fit your lifestyle, eating behaviour, budget and allow you to lose weight with far less effort. It’s adherence that is key. Let me help you with that.

My diet approach: less rigidity and more ‘real life’

A couple of comments on my Facebook page, a comment from a client that she wasn’t  ‘my perfect client’, and a post from one of my good nutritionist friends inspired me to have a bit of a think about how I approach nutrition, or the expectations that others have of my nutrition approach.

Whenever I put something out on social media, people will read from it what they will – I want them to comment and engage (why else would I put a post up?)  One of these was a comment I got after posting a recipe up on my page. Someone commented that she was very concerned that I say I follow a minimally processed diet approach, yet used a protein powder in my pancake recipe, clearly a highly processed ingredient*. She’s not wrong – protein powder is highly processed for sure, even the brands that I use and recommend others do: those that don’t have a lot of added ingredients bar the protein powder, some flavouring and stevia-based (or thaumine) sweetener . It got me thinking though. This person was annoyed that I was straying from their perception of what I advocate. If I could include protein powder in my recipes, clearly I’m not an advocate of the real food approach. How could people trust anything I say if I suggest that protein powder is okay? I wasn’t living up to her expectations of me, and she was disappointed.

It’s a tough balance: when I changed my philosophy around food I think I was a lot like other people – went too far in the extreme of finding the perfect real-food approach in an effort to ditch processed food. Legumes and all grains were off the menu (regardless of dietary tolerances, as this was the ‘perfect paleo’ way). All bread was to be avoided at all costs. Only drink red wine (less sugar) … It was 95% of what you’d call a ‘primal’ approach.

Like most people, though, I have settled in an approach to eating that is more practical to real life and, frankly, less exhausting. I have my diet non-negotiables –for me, I don’t touch diet soft drinks and chewing gum. In fact, I had a dream a few months ago that someone offered me a piece of gum and I took it. I woke up in a panicked state. This is because around 6 years ago I couldn’t go a day without having Wrigley’s Extra gum, and now I am scared that if I have it again that it would be a quick slide back into a daily habit that I couldn’t stop (even though when I gave it up it was literally like a switch had gone off in my brain and I couldn’t imagine having it again). I don’t have food allergies, so unlike other people, there isn’t anything that I must avoid or I’d be seriously compromising my health. That said, if I was eating the way I did during my Master’s degree at Otago, I couldn’t last during the day – I’d regularly have to nap in the afternoon under my desk after a diet coke and a massive ciabatta bun from Il Panificio bakery for lunch, which was backing up a large milky trim cappuccino and a dark rye sesame bun for breakfast. A carb overload and no fat or protein will do that to me (and a lot of people) – and don’t get me wrong – I LOVED it (and still would!) Just not how it makes me feel and, unfortunately, now I know too much about the long-term implications of eating such a nutrient-void diet). Huh. And I was doing a Master’s in nutrition at the time…

For everything else, though it is more about dietary principles rather than strict rigidity. Less religion and more realness. I try to avoid vegetable seed oils and artificial sweeteners that impact on blood sugar levels. However, if there is a dip that someone has brought along to a dinner party that has canola or sunflower oil as the second ingredient, I would likely have some if I thought it sounded nice, even if I wouldn’t buy it myself.  I avoid eating soy – especially products that use it as a cheap protein filler as you’ll find it in many packaged goods, though by now living in a vegetarian/vegan household, I eat organic tofu around once a week – and really enjoy it. I consume gluten when I have (for example) a date scone, or I really feel like toast. This might be once a fortnight. I drink wine. I have 3-4 alcohol free nights per week, but enjoy red wine (and coming into summer, white wine too – even though it has a higher residual sugar count). Not a lot – 1-2 glasses, and what they serve at the local bar is probably a more generous pour than we have at home. I like chocolate. I eat Quest protein bars (the varieties that don’t have sucralose as a sweetener in them – some do, some don’t) and use these as a bit of a stop gap as when training intensity ramps up (as it has over the last couple of months). I’m just hungrier in general and am not always organised. Despite their ‘organic’ label, these are about as far away from real food as you can get.

We buy white bread – the stock standard cheap loaves – as this is one of the only things that never comes home in the school lunch box during the week. If you’re wondering, I don’t think there is too much difference between white and multi-grain bread, really – it is all rubbish. I don’t eat it myself (any toast I have would be out at a cafe, a more delicious type of sourdough or ciabatta, probably), and can justify it till the cows come home but truth be told, getting any food in some kids can be difficult, so if they will eat a white bread egg or cheese sandwich that is going to at least fill them up, then so be it. A friend of mine commented on how she laughs when I post about lunchbox options for kids – and how (for her at least) it’s just a little unpractical and/or even if the kids show interest one day, the next they won’t have a bar of it. Now I get it. I really think I didn’t have a true appreciation for this and if I can somehow crack the nut that is ‘school lunches’ then I’d probably be a gazillionaire. One day. Maybe. (And if you have any bright ideas that I might not have thought of, pass them on!)

So, yeah. I still call my dietary principles ‘minimal processed food’ relative to the food environment and where I was at 7 years ago. Sorry to disappoint or concern anyone. Or perhaps this just makes you feel a little relieved that, despite best intentions, it doesn’t read like a perfect food environment or a perfect food diary, even for someone with my nutrition qualifications and practical experience. But that’s real life, and we do what we can. Some days are awesome, some weeks are awesome, and some, well, some just aren’t. That’s life, right? And when the dust settles, I’m pretty happy with it actually.  If you do what you can and have the best intentions going into it – then you’re always going to do better than if you didn’t try at all.

So please don’t think you have to be perfect – I’m not and nor should you stress about striving to be so. If you want some guidance at reaching your ‘happy spot’ click here to book a consultation or check out my online nutrition coaching services.

Jan’s story: a real food success story

When I met Jan, she had already lost 10kg through Jenny Craig but was super unhappy and hungry, experiencing bouts of hypoglycaemia (and used dates to help lift her blood sugars again, which would exacerbate the problem), had knee pain, was experiencing patterns of low mood and overall didn’t feel very good. Further, her HbA1c, measure of long-term blood sugar control, placed her in the pre-diabetic range (above 41 mmol/L). To my mind, this cut-off seems a little arbitrary. There really is nothing different between 40 and 42 mmol/L where one is ‘fine’ and healthy, and the other is ‘pre-diabetic’. Many GPs I talk to feel the same, but I digress.

We talked through her diet, which was a little like this:

  • Pre-breakfast: Cup of tea plus piece of fruit (off to do some work on the farm)
  • Breakfast: 2 eggs on toast with butter
  • Snacks: scroggin mix, fruit, rice crackers
  • Lunch: salad with greens with grated cheese and tomatoes
  • Dinner: standard kiwi dinner food, with some adjustments made thanks to Jenny Craig programme.

It certainly wasn’t a junk-food diet the way we understand ‘junk food’ to be, however it was low in protein with the balance of macronutrients geared towards higher carbohydrate choices: fruit, toast, dried fruit, rice crackers etc.

We talked through dietary changes and lifestyle changes, and I made several recommendations based on the information she provided and subsequent blood tests that she had conducted. The main shifts in her diet were to:

  • Anchor meals around protein, fibre and fat to stabilise blood sugar
  • Avoid snacking where possible
  • Removal of most carbohydrate (including fruit) to help lower her overall blood sugar level
  • Including raw apple cider vinegar around meals (to help with glycemic control)
  • Remove dairy (clinically I see many women in their late 40s and above benefit from removing dairy from their diet)
  • Supplementing with magnesium and chromium for blood sugar control, and supplements to help support her liver function
  • Slow cook meat wherever possible (to reduce the formation of advanced glycated end-products which are toxic, especially for someone with poor blood sugar control).

Over the course of the next 14 weeks, Jan has experienced the following:

  • Sleep has improved
  • Knees no longer sore when moving
  • Blood sugars have stabilised, no signs of hypoglycaemia
  • Mood has infinitely improved
  • Skin and hair are better
  • No cravings
  • Appetite is good, feels satisfied with food
  • Body composition changes: she has dropped 15 kg
  • HbA1c had dropped to 37 mmol/L (out of the ‘danger’ zone).

Importantly, her overall wellbeing is SO much better than it was. She sounds so much brighter on the phone, she feels so much better about herself and she has achieved so much. When we caught up two months ago at our previous appointment her weight had stabilised around 5 kg heavier than it is now, though she continued to notice body composition changes – her shape was changing but on the scales, it was the same. I see that frequently, and nothing is linear, of course. It can be weeks of plateauing on the scales before they shift. Is this a metabolic adaptation? Not sure. Usually it’s compliance to diet, though Jan had been consistent with her approach. Of course, there are things you can do to help move the needle a little bit if necessary, but sometimes it can just be a matter of waiting it out before the trend down continues. The key is to not be demotivated by this. Scales can be a good indicator of progress, but remember not to rely on them as the sole indicator. Luckily for Jan, she was experiencing the benefits of eating well every day, so even though the number on the scale hadn’t changed, she still felt good about her lifestyle change. Her husband has also benefited from her lifestyle change, dropping excess body fat by virtue of eating from the same food supply.

A typical day’s food intake for Jan now would be:

  • Breakfast: 2 eggs plus bacon and mushrooms
  • Lunch: salad, chicken, a boiled egg
  • Dinner: salmon, roast pumpkin and carrot and salad

OR

  • Breakfast: 3 scrambled eggs, tomatoes, spinach
  • Lunch: sushi (no rice), cabbage slaw
  • Dinner: butter chicken with cauliflower rice

If she feels like a sweet treat, she makes something like this Pete Evans nut bar, or mixes up some coconut yoghurt and frozen berries to make a sorbet-type dessert, and is completely satisfied. She was initially worried about my reaction to the nut bar, given it’s got some dried fruit in it, however she reiterated that she cut it into 30 pieces, froze it, and brings it out “not every day” to have with a coffee. Honestly, though, had she told me she ate it every day and got these physical and psychological benefits, then it is working for her regardless of what I think (in the context of an already stellar food intake). One food doesn’t make or break a diet.

She finds it is super easy for her to follow this way of eating and eating out or with other people is not an issue. She asks for dressings for salads, and sauces for steaks on the side to control how much of these she has, and to help avoid hidden added sugar or industrial seed oils that are commonly found in these foods. She is ‘busy’ but not overly active, and we are working on getting her resistance training up to help protect her bones AND increase muscle mass. These two things will help her overall health and prevent sarcopenia in later years. We are starting with home based activities for this. While she could have started this earlier, it’s sometimes easier to focus on one health behaviour and bring the others in – everyone is different though; so this needs to be considered on a case-by-case basis.

One thing she does find interesting is other people’s reaction to her weight loss, with some people asking when she will stop doing what she’s doing (as if it is a ‘diet’, which Jan isn’t on), or saying that she is getting ‘too thin.’ This regularly happens when someone loses weight and gains health; people are used to seeing a different version of them. To deviate from this can be unsettling. For others, they subconsciously take the actions of someone like Jan personally, like she (who is adopting the improved health behaviour) is doing it to highlight some failing of their own. While that might seem ego-centric of them, I don’t think it’s on purpose for most people! These people are often good friends and want to see you succeed. The important thing for Jan in this instance is to not take on board what others say and stay confident and strong in her approach.

So that’s Jan. Awesome, huh? She’s booked a holiday too – something she said she wouldn’t have contemplated previously. This has less to do with her weight (though certainly she can move around much more freely) but more about the increase in overall wellbeing that has occurred through adopting these changes. It makes me feel so privileged to work with people like Jan and share in their success. While I gave Jan the tools to guide her, the hard work was up to her.

Six things I think you should know about LDL cholesterol

Does bacon deserve the health halo it now seems to have in light of what is becoming common knowledge about saturated fat? Mm. Good question, and it probably comes down to context. If we were to position bacon against Flora Proactive, then that changes the question somewhat: which is better for your health? I mean, one is designed specifically to lower low density lipoprotein (LDL), aka ‘bad’ cholesterol (something we’ve been told for years to strive for) and is ridiculously expensive; the other is … well, bacon. Due to its saturated fat content (or perceived saturated fat, it contains less than 50% of its fat from saturated sources), it is always the second food which people think of when it comes to elevating cholesterol levels and causing heart disease – the first being butter.

Many clients come into my clinic with a total cholesterol above 5 mmol/L and are told by their GP that they should bring their cholesterol level down by way of eating low saturated fat, low total fat and reducing animal protein in their diet. OR (worse) go on cholesterol lowering medication (why is medication worse? Check out here and here). There are many things contributing to a higher cholesterol level, and the risk this poses to you is based on many factors. I’ve covered some of these (and what you can do about it) previously.

Here are 6 things I found useful to know about LDL cholesterol. I’m not talking about particle size, particle number, patterning of particles or Apo A or B, reverse transport cholesterol etc. Keeping it kind of simple. If you know more than your average Joe about cholesterol this will likely be a bit elementary. Otherwise:

  1. Most studies and media reports that report a reduction of risk of heart disease when taking cholesterol lowering medication focus on the relative risk. Relative risk – takes a small effect and it amplifies it. This makes the medication look far more effective than it actually is. Let’s explore what this means:

If you have a clinical trial whereby 100 people are given a placebo drug* and 100 people are given the experimental drug, you might find that 2 people in the placebo group go on to have a heart attack (2%), 98 have no adverse events. In the drug-treated group, 1 person has a heart attack (1%), and 99 people have no adverse events. The difference is 1%, however the relative risk reduction is 50% and a much more impressive number, don’t you think? Those reporting in the media certainly do.

  1. We need cholesterol to synthesise naturally occurring steroids in our system. It is necessary for life. It is the substrate for every sex steroid, for vitamin D, to make new neurons and new synapses to consolidate memories. Many people think cholesterol is in our body solely to clog arteries, and the lower the better. This is not the case. For example, in some populations a low total and LDL cholesterol are linked to higher incidence of depressive symptoms. A low cholesterol level may also result in less synthesising of vitamin D in the body, lower hormone production and an impaired immune system.
  2. LDL is an innate part of the immune system. When there is damage to the artery, you have susceptibility to infection, and there is evidence of pathogens present in plaques. When there is damage to the artery and artery wall, resulting in atrophy, there is an infusion of white blood cells as well as LDL cholesterol which work together to promote inflammation (for healing purposes). Blaming LDL for creating damage is like blaming the fireman for creating a fire.
  3. There is NO level of LDL that is unhealthy. There is an assumption that LDL cholesterol is inherently atherogenic and that above a defined level it is dangerous – there is something about the LDL packaging of cholesterol that causes heart disease. That’s not the case, and some experts in the field believe there is no level of LDL that should be treated with a statin. Researchers reviewing the literature have found people with high LDL with no heart disease. The cut-off of 4mmol/L or 5mmol/L depending on your reference point is an artificial distinction that has been created to suggest LDL is inherently toxic to the heart and cardiovascular system. Now there are people who have a genetic predisposition to storing cholesterol, so they have an increased risk? Actually research looking at the lifespan of people with familial hypercholesterolemia (FH, a mutation in the LDL receptor whereby the end result is elevated LDL cholesterol) have found that, aside from a subsection of the population, there is normal lifespan, with just a small number of these people going on to develop heart disease. There are people who have other genetic variants which do result in build up of LDL cholesterol, and we don’t know enough to say that a very high LDL level is NOT dangerous – however the likelihood of harm will be increased with the presence of other risk factors for cardiovascular disease, such as high blood pressure or smoking.
  4. It is not LDL that is causing heart disease. Blood cholesterol (including LDL) is high in people consuming a higher fat diet. However, research shows that other biomarkers are not only fine, but can be improved when transitioning to a higher fat diet from the standard western diet. A recent paper found that people 60 years and older who have the highest LDL live as long or even longer than those with low LDL. They have lower rates of cancer and lower rates of infectious disease.
  5. If it’s not LDL cholesterol, then what is causing a heart attack? A critical trigger factor is coagulation. We rely on the coagulation factors in our bloodstream to create a clot when we become wounded and begin to bleed. However, our blood can clot without there being a wound. High stress, tobacco smoke, high blood sugar all trigger clotting mechanisms. It looks like this:
    1. In our artery wall, there are tiny arteries which feed to the inside of the artery (called vasovasorum).
    2. Vasovasorum are easily blocked or clogged by clots.
    3. If these can’t feed our artery wall, the wall essentially becomes hypoxic and the tissue dies.
    4. When the tissue dies, the LDL cholesterol comes in to repair it, and this happens repeatedly, causing the artery wall to become thicker and thicker until it chokes the artery.
    5. When you combine this thickening of the artery wall with something that might trigger clotting of the blood (such as high blood sugar, smoking or a stressful or emotional event etc), a clot will pass through the narrowed artery,
    6. The clot will eventually block the artery entirely and the result is a heart attack.
    7. None of this is caused by LDL cholesterol.

What really matters is keeping your clotting factors inactive until they are needed. Most people (unless they are haemorrhaging) don’t need their clotting factors on high alert all the time.

So, which is better for your health? IMO – while bacon may not be a health food, I’d choose it over the Flora (preferably free range, minimal added preservatives, along with an abundance of vegetables). Flora doesn’t have a lot going for it, TBH, and while it may lower your cholesterol level, how important is that really? If your cholesterol levels are high and you’re not sure of your risk, get in contact with someone like me who can work with you to address the lifestyle factors that might be driving up your cholesterol levels and contributing to health risk.

This bacon isn’t preservative free, however it’s the only one I could see that had less preservatives and was free-farmed, so using it as an illustration. Henderson’s is free of preservatives but only select supermarkets carry their free-farmed variety FYI

 

48 real snack ideas for the uninspired

Regardless of how much you love thinking about food and trying different ideas, sometimes you just need some inspiration, especially when you’re up against it with the usual convenience carbohydrate-based foods that adorn our supermarket aisles – readily available and at your disposal. This is true of both the recently converted person and the seasoned LCHF’er* (that sounds a bit religious, really, but to be fair, nutrition is a religion for a lot of people!)

We’ve got to be realistic – a good diet (and decent snacks) don’t happen by accident. These types of ideas take some preparation and planning. However I encourage you to do it as you are totally worth it! You know how bad you can feel when you eat something you don’t want to, but it was the only choice. Like that double-sized Kit Kat at the petrol station because you were starving and this was the first thing you could see and, hey, cheaper than the single sized one.

I’m not talking ‘bad’ as in feeling guilty – let’s try to remove any emotional attachment to food. I mean, I love talking, preparing and eating delicious food – it brings me joy! But I have long realised that any negative emotion (such as guilt and shame) that is attached to food choices does not serve anyone. It creates such negative energy and can perpetuate behaviours that we are trying to avoid, such as:

  • eating quickly without really chewing (so no one notices!),
  • eating more than we need (as we don’t appreciate what we are eating, our appetite hormones and taste buds don’t register that food has been consumed),
  • eating it to ‘get rid of it’, along with declarations of ‘that’s the last time I’m going to eat X so I’m going to make the most of it.’ (Okay – so it’s unlikely to be the last time that you eat whatever food X is, and unless you have an allergic reaction that makes it dangerous to eat (ie gluten for a person with coealics) or extremely uncomfortable, then there should be no reason to avoid it forever.)

I’m talking chocolate, biscuits, chips, etc – high sugar, high fat high caloric and low nutrient foods. Sure, these types of foods aren’t ideal to consume on an everyday basis for most people, however no one food ruined your diet and subsequent health goals. It’s more unhelpful behaviours and habits that are driven by our physiological response to these foods. These ultra processed foods (combination of sugar, starch, vegetable oils) leave little work for our body to do when we eat them, meaning the starch and sugar hit our blood stream quickly. This increase in blood sugar will drive an insulin response that clears the blood of nutrients (sugar and fat), and takes it to where it’s required, or to store it for later use. The body prefers to keep things relatively stable, so if there is an excess of sugar in your bloodstream, it is going to be on it to clear it out. If you’re very active and eating for fuel, it will go to the working muscles. If you’re behind a desk on a standard work day, then it’s more likely to be the latter. That can happen at such a rapid rate that your sugar level dips below normal (an over-correction), sending stress signals to your brain to resolve the issue and bring your blood sugar levels back up to within normal range. Cue: hunger, potential light-headedness, loss of concentration and cravings for sugary or starchy foods – the foods your body knows will solve the immediate ‘crisis’.

So, what to do?

First: do you need to snack? If you eat three decent meals a day, you probably don’t and by decent, I mean meals that include a good hit of protein, some fat for satiety, may include some carbs (of good quality, such as kumara, potato, some fruit, dairy for the dairy tolerant) and an abundance of non-starchy vegetables. How much? Check out the graphic below. If you hit this and you don’t have high energy needs BUT still snack, think about whether it is out of habit or hunger? Habit can drive our appetite to eat almost as much as a physiological need for nutrients.

And if you do need a snack?

These snack options listed combine any carbs with fat and/or protein to slow down the release of glucose into the bloodstream and will help keep you fuller for longer. Perfect. These are from a FB post I put up last week, and a few of my own thrown in there too. Some are grab and go, some require a little bit of preparation to be ‘grab and go’, and some require a bit more time in the kitchen, but it will be worth it when you need something to tie you over.

Starving? Read this and you won’t be.

One of the biggest downfalls I see with diet is the lack of protein across the course of the day. A typical pattern I see when I talk to people about their food intake and their appetite is:

“I’m ‘good’ all day, but can’t control myself come 5pm”

OR

“I’m fine all day, but after dinner regardless of how full I feel, I’m not ‘satisfied’ ”

OR

“I’m ‘good’ till Wednesday then it’s all downhill from there”

Any of this ring true? The reason I bring this up is that many people report being absolutely starving, constantly thinking about their next meal and (more often than not) their frustration with being unable to lose body fat as they view their diet as being pretty good. When we delve further, I see quite clearly that when people are “good” it generally means they are undereating during the day, and this leads to almost a binge-like pattern later in the evening, or just an inability to stop snacking. A typical pattern might be:

  • Breakfast: cereal + fruit + trim milk (cos, you know, fat is bad)
  • MT piece of fruit/trim latte OR nothing
  • Lunch: chicken salad perhaps 50g chicken, no-fat dressing, no carbs (hey, we got rid of them back in the 90s!)
  • AT: nothing, or a carrot or similar
  • 5pm: a small handful of nuts, then a slightly larger one.
  • 13pm: a carrot. And hummus
  • 21pm: a few spoons of PB,
  • 47pm: cheese while making dinner
  • 10pm: leftovers off the kids plate,
  • 32pm: dinner (full!)
  • 20pm: piece dark chocolate
  • 35pm: bite of icecream *well I’ve blown it now*
  • 40pm: bowl of icecream *I’ll be better tomorrow*
  • 10pm: 3 rows of chocolate…..

Does this look familiar? While they may be low calorie/fat/carb during the day, people with this dietary pattern will generally consume more calories than they realise in that pre-post dinner window. This isn’t just about calories and fat loss though. Many people also suffer from anxiety around their food intake, gut or digestive issues from consuming more food than what is comfortable, sleep issues due to an excess of food close to bedtime, and unhelpful self-talk related to their perceived lack of control. This last point can be particularly damaging to long term success, as for some this can perpetuate feelings of failure and subsequent behaviours which make it difficult to change in the long term. Other long term consequences of a low protein and low dietary energy early in the day include reduced muscle mass, reduced metabolic rate, low mood and a greater propensity for fat gain in the long run.

How to prevent this?

Eat more protein at the start of the day – it is more satisfying and is digested a LOT slower than other nutrients, and will prevent overeating later in the day. What you eat at the start of the day really impacts how you feel and what you eat at the end of the day. Many experts in the field of protein research view 0.8-0.9g protein per kilogram of bodyweight, based on nitrogen balance studies, are likely underestimating overall protein requirements. This is especially true for those in the older age bracket and for people wanting to drop body fat where studies such as this have found that 2.4g protein per kg bodyweight can help maintain metabolic rate and protect muscle mass. Clinically (which, to my mind, is as important as what the literature says), very few of my clients thrive on a lower protein diet. Athletes (FYI) are recommended around 1.7-2.2g per kg bodyweight and in general a higher protein intake will benefit mood, sleep, blood sugar and appetite.

So what does 2.4g per kilogram look like for the myriad of people out there wanting to drop body fat? IE if you weigh 75kg, your protein intake should be around 180g. If we consider the standard protein sources available, then it might look a little like this (amount of protein in brackets):

  • Breakfast: 4 eggs (29.2g) – with vegetables, scrambled, cooked in butter, coconut oil or olive oil
  • Lunch: Medium chicken thigh 146g (34g), sliced up into salad with olive oil dressing and lemon
  • AT: ½ cup of cottage cheese (18g) with pesto mixed through
  • Dinner: Medium steak (186g) with roast vegetables 57.3g

Well, that is 139.4g of protein per day, around 1.86g per kilogram body weight, leaving an additional 40g of protein being derived from plant sources. You can see that you have to eat a lot of food to get your protein in – which is completely different from the ‘being good’ scenario above.

While the run down of foods to eat above may freak you out if you’re used to a cereal and salad diet – don’t be scared. If your dietary pattern looks much as I described above, allowing more protein earlier in the day will have a huge influence on your overall intake – the pattern of grazing late afternoon into the evening will change. I promise. I’ve written about the protein leverage theory before when discussing the National Heart Foundation’s food guidance system (click here for that post) – that the body has an innate requirement for protein and will drive appetite until this is requirement is met. If you eat a lower protein diet, research suggests you may eat more overall calories (and calories from refined carbohydrate) compared to people consuming a moderate protein diet. I know many people don’t like eating more food earlier as they don’t believe they have the willpower to stop. I recently wrote about the main physiological driver of ‘lack of willpower’, and eating more protein will kill this response pretty quick. You just have to try it. When combined with fibre, a bit of fat and carbohydrate that takes longer to digest, protein is (to my mind) the nutrient to focus on for controlling appetite, hunger levels and helping maintain an optimal body composition.

Protein quality definitely counts here too. This measure has been revised recently to reflect updated knowledge regarding the digestibility of protein, however regardless of technique used to establish bioavailability of protein source, animal protein consistently scores higher than plant protein in terms of protein quality (with 0.75 as a cut-off for good digestibility – see here for some food-based tables). This will have implications for their effect on appetite (i.e. ability to keep you satisfied). In part this is due to the presence of anti-nutritive factors in plant based proteins (such as lecthins, tannins, phytates etc) that prevent our absorption of them (see here for a comprehensive report on the digestibility of protein). This is not to say that plant protein doesn’t count. I have many clients who are vegetarian and, for them we ensure a good intake of eggs, cheese and protein powder (whey, pea or egg white protein powder for a good variety). People following a vegan diet are a little more challenged. While they will get protein from legumes, nuts, edamame beans, tempeh and seeds, I recommend (again) protein powders, and incorporating a variety of these (such as pea, hemp and sacha incha) in their daily diet. These are lower in overall protein compared to, say, whey (sacha incha has around 12g per 20g serve (60% protein), compared to whey protein (17-18g, or 85-90%). But if we are looking to increase protein across the course of the day, these will certainly be useful.

So…what about you?

If you’re a numbers person, think about your goals (weight loss, muscle maintenance etc) and shoot for the grams per protein I’ve mentioned above. Use Easy Diet Diary, My Net Diary, Fat Secret or Cronometer to find out how much protein is in the foods that you’re eating, and what the distribution of it is across the course of the day. Then use the information provided to plan for a higher protein intake and a more even distribution. At the very least, aim for around 25-30g of protein in your meals. If you’re not a numbers person, then use tables like these to give you an indication of where protein is in food. Aiming for:

  • 3-4 eggs at breakfast, or 120g protein-based food or 1-2 fist-sized worth; and
  • at least 120-150g of protein-based food at lunch (or 1-2 fist-sized); and closer to
  • 160-200g protein-based food at dinner (or 1-2 fist-sized); and

shooting for the higher numbers the more active or the bigger you are and THEN base the remainder of your macronutrient intake (carbohydrate and fat) around this – and don’t forget the abundance of non-starchy vegetables. If you want some help with this, get into contact with me or sign up for my online nutrition coaching – this is pretty much how I build my meals. While initially you may feel hungry, this will likely be habit rather than actual hunger (or a hormonal response, as your body’s appetite hormones work on a circadian rhythm and ghrelin may well be released as your body is used to eating at that time. Brushing your teeth is one of the best things to do to cut that hunger. If you wait it out, it will eventually pass and you’ll easily eradicate the feeling of hunger, the grazing later in the day and regain the feeling of control around your food (rather than letting the food control you).

Time restricted eating: when you eat matters

Intermittent fasting is an increasingly popular phenomenon among people wishing to improve their body composition and their overall health – almost as much as consuming the latest superfood.

Intermittent fasting (or time restricted eating, as it is known in the scientific literature) is when we restrict our eating during the day to a window of from around 8 hours to 12 hours, and has been popularised by the fitness industry in recent years. There are different ways to approach it, though from a health perspective, eating earlier in the day to allow for the feeding to align with our body’s circadian rhythm may optimise the health benefits for overall longevity. Fasting has been a practice undertaken for centuries in some cultures, and research reports favourable effects on many markers of metabolic health, including blood lipid profile, blood glucose metabolism and hypertension when these populations have been studied. More recently, researchers have investigated different time restricted feeding protocols in relation to risk of cardiovascular disease, neurological disorders, diabetes and some cancers using rodent and human trials. The longer time spent fasting may have pronounced health benefits, though recently a more conservative method (of even an 11 hour fast) has emerged as being beneficial for certain populations. Indeed, time restricted eating is being thought of as an easy to implement, effective lifestyle intervention that could help improve appetite control, markers of overweight, inflammation, blood glucose metabolism and hypertension, all reducing risk of cardiovascular disease, diabetes and some cancers. This recent small study found that late night (or prolonged eating periods) increased fasting glucose, blood triglycerides, insulin and weight gain.

When healthy adults eat meals that are identical in terms of macronutrients (ie carbohydrates, proteins and fats) and caloric load at breakfast, lunch and dinner, the postprandial (ie. after eating) glucose response to the meal is lowest after breakfast and highest after dinner, even though the meal is identical. This is one example which suggests that our metabolism, and response to food, changes across the course of the day (see here). We are diurnal creatures – we do most of our activities during the day (including eating, working, exercising) and we rest at night. This is controlled by our internal clock in the brain, the superchiasmatic nucleus (or SCN) which in turn influences smaller internal clocks (or oscillators) in the peripheral tissues of our body. These clocks control thousands of genes within our body, including those that regulate our metabolic processes, which accounts for around 10% of our entire genome. While light is the major cue for the SCN in our brain, timing of food intake influences the circadian rhythm in the other tissues, including the liver, which has implications for metabolism. This tells us that our basic metabolic physiology is supposed to behave differently according to the time of day – this is everything from making neurotransmitters, to making insulin, to glucose transport inside of cells, to fatty acid oxidation and repairing cellular damage. It makes sense then that when we eat has just as important implications for our health as what we eat. Research investigating the health effects of fasting has found that anything that breaks the fast will break the fasting period, including no calorie options such as black coffee and even herbal teas. This is because there are compounds within these fluids that require breaking down by the liver. That is not to say that people don’t experience benefits from fasting if they consume a hot beverage earlier in the day (as is often recommended to help get through the morning hours and comply with a 16:8 protocol) or limited calories (for example, 50 calories), however longevity benefits may well lie within the strictest definition of fasting.

With the advent of artificial light, and the changing structure of work schedules (combined with the increasing busy-ness of everyday life), this has elongated the period of time that people eat, which has negative health consequences. While you may have heard in media reports of scientific studies that eating late at night makes no difference to overall weight loss, the focus on weight ignores the more important, underlying metabolic and chronic disease risk that eating late into the evening can have on health outcomes. It may be easier to regulate appetite too, as  research suggests that appetite hormones respond more favourably to eating earlier (8am to 7pm) than later (noon – 11pm), and the level of satiety achieved with this could prevent overeating. This is relevant with time restricted feeding as research has shown that more frequent eating patterns can be detrimental to metabolic health if consumed close together. One study found that participants who ate excess calories consuming their food over three meals and three snacks had increased visceral (stomach) fat deposition, liver triglycerides and lower liver insulin sensitivity compared to those consuming the same number of calories over three meals. The snacks were consumed later in the day, and after each meal, so elongated the overall eating period.

Animals limited to 9-12 hours feeding period, but not limited in the number of calories they eat have experienced benefits including decreased fat mass, increased lean muscle mass, improved glucose tolerance and blood lipid profile, reduced inflammation, higher volume of mitochondria (the energy powerhouse of our body), protection from fatty liver and obesity, and a more favourable gene expression. In humans, research studies suggest that eating within a time restricted window of 11 hours (say, 7am to 6pm) is associated with a reduction in breast cancer risk and occurrence by as much as 36%. Earlier eating time has resulted in more effective weight loss in overfat people, and every 3 hour increase in fasting duration was linked with 20% reduced odds of having an elevated glycated haemoglobin (HbA1c), a marker of long term blood sugar control. For every 10% increase in calories consumed after 5pm there was a 3% increase in c-reactive protein, a biomarker used to measure inflammation (the underlying process that, when elevated long term, can influence risk of diabetes, cardiovascular disease and some cancers). Finally, when meal times were constructed earlier in the day this resulted in a 10% decrease in c-reactive protein. Eating within a 12-hour window improved sleep and weight loss within an otherwise healthy population. You can see then, the myriad of potential benefits to eating within a time restricted eating – could it be worth trying to fit into your lifestyle? And if so, how to do it?

There are many different time restricted eating protocols to choose from – and the type of fast you choose to do really comes down to what works for you. The 16:8 protocol that seems to be most popular is a little aggressive for anyone new to fasting, and this may ultimately leave you feeling hungry, cranky, and vulnerable to overeating later in the day – undoing any potential health benefit that has been shown in the research. Indeed, many people I see that try this as their first experience report that they can successfully get to 11am or lunchtime without eating, but once they are home from work, no amount of food will keep them full, eating right up until bedtime.  My advice is to start a little more conservatively. Given that (in an ideal world), we sleep for 8 hours a night, not eating in the 3 hours leading up to bed time should be a good place to start for most people, thus it gives that 11 hours where some of the health benefits begin to be realised. From there, once adapted, you could try to push it out by an hour. While the most potent benefits occur with the strictest definition of fasting, the blood glucose and lipid improvements, along with fat loss can still occur in those whose definition of fasting refers to calories, not coffee and tea as mentioned above. That the benefits occur in the absence of caloric restriction is important to reiterate, however by restricting the eating period, many people also reduce overall caloric intake, which can further improve overall metabolic health and body composition. Fasting doesn’t appear to be something you must do every day to see the health benefits either, and even 3-4 days a week could be beneficial for metabolic health.

That said, this reduction in calories and extended time NOT eating may not be good for all, especially if your notice increased anxiety, sleeplessness or disruptions in hormone balance, so it is always best to proceed with caution. It would also be prudent for any individual with a health condition to discuss with their health professional before embarking on time restricted eating, especially the more aggressive protocols.

I got a question on my members’ Facebook page a couple of weeks ago regarding water retention. There is nothing worse than a bloated tummy – it can not only make you feel physically uncomfortable, but can also wreak havoc on your psychological state (as many people equate the bloating to ‘feeling fat’, despite there being no relationship between the two). Further, a bloated stomach impacts on your ability to move properly. We can’t engage our core muscles, so aren’t able to move, lift, push or pull in a way that is functionally optimal. This has important implications for our core strength and injury prevention. Of course water rentention affects more than just our stomach – a long haul flight to somewhere warm can turn anyone’s lean calves into kankles due to changes in the pressure in the capillaries, causing fluid to leak out into the body tissues. There can be many reasons for this, so I thought I would investigate the most common causes and possible solutions.

  1. Minimize your sodium intake. Although sodium (aka salt) is an essential mineral because it’s used to regulate the fluid levels in body tissues, bringing water into the cells. Excess intake of sodium may cause excessive fluid retention in the body tissues. While the evidence behind this recommendation suggests it isn’t something that affects everyone, this may help some people, particularly those who are salt sensitive or hypertensive. Do note, though, that if you follow the types of principles that I suggest, your diet is probably quite low in salt anyway, as most salt comes from processed foods (around 70%). However, there are whole foods that are high in sodium, such as cheese, miso, cured meats and biltong, so you could reduce these, and avoid adding salt to your food to see if this makes a difference.
  2. I probably don’t need to tell you to avoid eating too many refined carbohydrates – these tend to spike insulin, which causes sodium (often found in these foods) to be re-absorbed back into the kidneys, thus increasing water retention. Your best bet for carbohydrate foods are those whole-food, minimally refined varieties that have negligible sodium for a start, and that you eat in a mixed meal with good fats and proteins to help slow down the release of carbohydrate into your bloodstream, minimising insulin response.
  3. Any form of dehydration can cause your body to hold onto water. Therefore, ensure that if you drink alcohol, do extended exercise training sessions, or are in a hotter environment that you remain well hydrated to offset any potential for dehydration. The fluid you lose during exercise should be replaced in the three hours after training, and at 1.5 times the amount lost – you can work out how much this is by weighing yourself before and after an exercise session. The amount of weight lost roughly equates to the amount of fluid lost. Prior to drinking alcohol, have a couple of glasses of water (this will also help slow down your drinking). And be an adult about how you drink: is it necessary to drink more than a few in any one sitting?
  4. Take adequate amounts of vitamin B6 combined with magnesium. For women, prior to your period you can feel a little bloated and that you are retaining water. Interestingly, however, some research investigating the timing of this around the menstrual cycle has found bloating occurs more in the onset of your cycle (day 1) after which is rapidly declines, despite the perception of puffiness or bloating in the week prior to menstruation. This puffiness, however, could well be related to food choices in that week, as the intake of higher sugar choices can increase for some.
  5. If you have water retention before your period, you may, however, benefit from taking both a magnesium supplement (at 250mg per day) combined with a vitamin B6 supplement (40mg) daily – a study found this combination the most effective for decreasing premenstrual symptoms when administered for two months by balancing your hormone levels.
  6. Potassium works in conjunction with sodium, pumping fluid out of the body cells. Therefore, if you aren’t consuming enough then it could cause problems with water retention. The reality is, though, that you are following the meal plan and including plenty of vegetables, your potassium intake is likely fine. However, if you don’t have a good intake of vegetables (at least 7 serves per day) then increasing these is a good idea. This will also bump up your fibre intake, which can further help reduce fluid retention.
  7. Take natural diuretics. Dandelion root has long been used to help flush water out of the body – therefore investing in a good tea such as this Golden Fields one is not only delicious (often used as a substitute to coffee), it will also be beneficial. In addition, this kidney cleanse tea from Artemis has other natural diuretics to help flush water out.
  8. Exercise regularly. Exercise can help reduce water retention, not just by increasing sweating, but by moving water from the intercellular compartments to the muscles.
  9. Increase your caloric intake, if only for a day. I know – this one sounds weird, but a ground-breaking study in the 1950s called the Minnesota Experiment found something interesting mid-way through their study. The study followed men on a 1500 Calorie diet for 6 months, and subjected to hours of hard labour per day. Half way through the trial the men were allowed a celebration meal, effectively increasing their caloric intake to 2300 Calories. Following a night of getting up to go to the bathroom several times, the men were a few pounds lighter the following morning. Obviously, the weight lost was water weight – but why would this be the case? Potentially the long-term calorie deficit caused an increase in cortisol levels, and this increases water retention in the body. By increasing caloric load, the body reduced cortisol levels and this reduced water retention.
  10. Reduce overall stress load. As we have just discovered, higher cortisol levels will increase water retention, therefore anything you can do to reduce stress is going to impact favourably on water loss. Let’s not forget the impact that high stress levels have on blood sugar levels, inflammation and fat gain (to name just three areas it impacts). While stress is a perception of a situation, and changing your mind-set is one of the best things you can do to lower stress levels, ensure you are getting adequate sleep, time in nature, time with loved ones and taking time just for yourself. These are going to help lower your cortisol levels and combat any stress-related water retention.

So… not a definitive list, but hopefully a few pointers to help you get to the bottom of your fluid retention issues and make some improvements.
