Fuelling the fat-adapted athlete

On August 1st I’m releasing my athlete-specific meal plan, which is a long time coming given that I consult with many endurance athletes! It’s hard to be specific with a general plan, clearly, particularly when it comes to training nutrition, so when you sign up I encourage you to contact me to see if we need to tweak the elements of this plan to suit your training.

The goal of an athlete training plan is to provide fuel where required, be strategic about the type of fuel and when to have it. I want to help make you a more efficient athlete – so your training and recovery is optimised to enable you to get out there day in, day out in the best possible shape. This will allow you to show up to the start line (or game day) in the best position to do your best. Like recovery, nutrition is vital to enhancing fitness gains from your session – eating the wrong types of food increases oxidative stress and dampens down your immune system, leaving you susceptible to inflammation, illness and injury. If you don’t recover effectively from the previous training session, your ability to get out the next time and hit certain paces/power is compromised – therefore overall fitness gains aren’t realised and you may not reach your potential awesomeness. I’ve written about this previously in more detail here.

To be metabolically efficient, we want to be strategic about when and how we have our carbohydrate, how much we have and the quality of the carbohydrate source. That is why in the plans I focus on adding fruit, kumara or potato after training if the training requires additional carbohydrate to support recovery. By removing carbohydrate from the pre-training meal/snack, we don’t have an insulin response that will drive circulating glucose (what carbohydrate is broken into) in to your muscle cells, shutting down lipolysis (fat burning). The body will be forced to use alternative fuel sources such as fat which, as an endurance athlete, we should be primed to do. The reality is, though, the modern diet that a typical athlete follows has made sugar burning the default training state, even at low intensities. Even the leanest marathon runner has enough fat calories on board to go out and run back to back races – accessing this though is the problem! Fat as a fuel source creates a lot less oxidative damage and reactive oxidative species, thereby the inflammation you experience post-training is reduced, recovery is enhanced, and you’ll be able to hit the next session fighting fit. We need to adapt from a carb burner to a fat burner for you to go out and train and not risk bonking or running out of fuel. The switch over doesn’t happen overnight, and if you’re new to this approach then training can feel pretty sluggish to begin with – but hang in there as it does get easier!

There are different approaches to fuelling depending on your goal:

Pre-training

If body composition improvement is your goal, it is best to do fasted training sessions or use coffee/caffeine as an ergogenic aid and fuel afterwards. This doesn’t mean that you’ll lose MORE body fat than if you were just to reduce calories, but it will force your body to tap into its own reserves, which (when combined with this dietary approach) I’ve clinically seen helps accelerate fat loss in the context of this eating style. For extended, longer duration >3h+ then having some fuel (as suggested in plan) can be a good idea, or starting fasted and taking on board fuel after 45-90 minutes depending on session is optimal.

If you are happy with your body composition or do not want to drop any body fat, then you can choose to take on board some fat before training – such as cream in coffee, MCT oil powder in coffee, or ketones. By fueling before training, you will shut down your own fat oxidation, but be upregulating pathways for fat oxidation, however it will be burning the fat that you consumed. This option is also good for people who have higher cortisol levels – training in the absence of any fuel can further exacerbate the ‘stress’ response from your hypothalamus (brain). Taking on board some calories sends signals to your brain that there is no need to stress. Taking the ketone supplement has been found (compared to fasting) to upregulate fat oxidation at lower given intensities; once the intensity rises to a high intensity, the opposite may be true (potentially due to the ketones being used to spare glycogen at the higher intensities).

If you struggle to maintain your weight and need to work at keeping calories high, then adding in some additional protein alongside could also be a good option – this could be a couple of hardboiled eggs, some scrambled eggs, additional fat-based calories or a smoothie based on nuts, avocado, some protein powder, coconut milk, greens, with no fruit). Again, this will provide a minimal insulin response, meaning your body will be burning the fuel you provide it (fat calories) and therefore working towards improving metabolic efficiency.

In all instances above, 10g of branched chain amino acid powder can help fuel a longer session – just mix in water beforehand.

In a perfect world, the best type of training to do if you are new to this is low intensity training; this is because your body needs to relearn how to burn fat as its primary fuel source. The ultimate goal down the line is to become metabolically flexible (ie easily shift between both sugar burning and fat burning) – and that will happen! That means the natural switch over to burning sugar that occurs when training at higher intensities will not impact on your fat-burning capabilities at the lower intensities. Right now, though, if it’s all new to you, your default is to burn glucose at that high intensity. Any shift back into glucose burning at this stage will impact on your ability to burn fat and can leave you in no-mans land when it comes to training. What I mean is, you are following a lower carbohydrate approach to diet, so there is no glucose on board as a ready source of fuel, yet you are too high intensity for your body to use fat as a primary fuel source (at this stage). No mans land.

However, it rarely happens that an athlete is always training low intensity, even in their off season. Therefore supplementing with an exogenous ketone supplement (such as Pruvit) provides your body with fuel the way a carbohydrate gel provides glucose. Ketones are the byproduct of fat metabolism, and when you burn fat as a fuel source, your body generates these to support metabolism. At a high intensity if you’re new to this, taking exogenous ketones provide you the fuel to enhance fat oxidation before your body has the machinery in place to do it for you. Otherwise the intensity will force your body to switch back to glucose burning. Remember, in the initial phases of your fat-fuelled approach, your body has to upregulate the machinery required for fat adaptation – it isn’t the default fuelling response. Any opportunity to switch back to burning sugar, it will take it.

Taking the ketones (along with MCT oil powder) will provide the fuel you need for the training without the need to use glucose, and is recommended in this instance. Further, ketones aid in recovery from longer sessions, and most athletes I work with who use them experience reduced inflammation, less excessive hunger, and can go for longer at a higher given intensity without an increase in their heart rate or perceived effort. Most have also experienced improved body composition due to these reasons. My recommendation is to have ½ sachet of the ketones and you can include 10g of MCT oil powder with it prior to your session.

During training:

 Shorter training up to 2h, low-mod intensity

Nothing – perhaps water, or an electrolyte fluid (no carbohydrates required*)

 Medium length from 2-3h low-mod intensity

Evaluate how you feel, take some MCT mix (see below), Superstarch (30g/hour in 750 ml bottle), ketones as below (sachet in 750ml bottle, 1/3 bottle hour), otherwise just electrolyte fluid.

Longer training: over 3h

36g MCT oil powder + 20g BCAA + ¼ tsp salt in 750 ml bottle OR sachet ketones, 18g MCT oil powder + 20g BCAA in 750ml bottle – ¼ bottle per hour AND every 45 minutes have something small, solid, food based: ¼ – ½ Cliff bar, 30g cheese, hardboiled egg, small handful cashews, ½ UCAN superstarch bar, homemade bar (such as apple pie blondie).

If including high intensity intervals

Try carb rinsing: 5-10 minutes before starting effort, have a glucose tablet, thereby trickling in carbohydrate – this method tells your brain you’ve had carbohydrate onboard without taking anything on. OR have sachet ketones in drink bottle as above.

*may need something if getting into it for first time, and suggestion is the ketone supplement here to help aid the fat oxidation pathways.

 Post-training

If body composition improvements are a goal, train around your meals so you don’t need to eat in addition to them, also can create a ‘train low’ environment by withholding food for around 45-75 minutes to further enhance fat oxidation. If higher intensity effort, include 10g BCAA powder in water post-training to preserve muscle mass.

If happy with body composition, then you can do as above or add in a protein shake with around 25g protein, use unsweetened almond milk to help provide calories and preserve muscle mass. Having the other ½ of your ketone sachet here can enhance recovery. Include 10g BCAA in water post-training to preserve muscle mass.

If you struggle to maintain your weight (or you are training hard again in next 8 hour period), then adding in the protein shake as above, plus serve of good quality carbohydrate such as kumara, potato, a piece of fruit can provide calories plus easily digested fuel to support recovery. Including the other half of your ketone sachet here can enhance recovery and include 10g BCAA in water post-training to preserve muscle mass.

In all instances, if the training is long, then I think the benefits of post-workout fuel outweigh ‘train low’, especially if you have a heavy or longer session the next day as a lot of ultra runners or triathletes do.

This isn’t definitive, and someone else will have a different approach, however these are generally the guidelines I have used that work with clients and that may work with you.

Remember, though, the best way to get fat-adapted is to adopt a daily diet that supports fat metabolism – click here to sign up to my plans and use the above guidelines to support your training.

The fuel I used pre-half marathon at the beginning of my marathon training program: 1/2 ketone sachet, MCT oil powder, coffee and PB.

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.

LCHF…why isn’t it working for me? (Part 2)

Last week I posted three reasons why many people undertaking a LCHF diet stall with their success or never get it off the ground to begin with. The following delve a little deeper into the less obvious reasons why people struggle with their diet, and offer some options to help troubleshoot.

  1. Fat doesn’t fill you up. For some people, they don’t feel satisfied when swapping out their carbohydrate for more fat. If it takes a few handfuls of nuts or half a block of cheese to feel satisfied, then there can be some serious increase in calories that isn’t compensated for by an appropriate increase in satiety from the meal. Yes, cheese and nuts contain protein, but to be honest I treat them more as sources of fat than I do protein. If this is you, then.
    1. Increase the portion of protein you are consuming with your meals. I know many people are scared to consume more protein because protein can be broken down into glucose in the absence of carbohydrate, therefore pushing up their blood sugar levels. For people on a ketogenic diet (where 80% of their calories should come from fat), or those metabolically damaged (whereby there is a dramatic change in blood glucose response from a protein-rich meal), this may be a problem. For most people though? upping protein by 1/3 of a serve is no biggie. Still hungry? Up the protein some more.
    2. Drop out some fat –make room for the added protein by dropping out some of the fat – you could start with ½ – 1 serve and see how satisfied you feel when you do that. A serve of fat is typically 1 tablespoon of oil or butter, or ¼ avocado.
  2. You’re eating too much in one meal. A lot of people move from three meals a day, to two a day, to a ‘minimal food during the day’ approach, to sit down to a large meal at night, especially if they’ve been in the LCHF way of eating for a while and are further tweaking it. This may be awesome for some people, but not all. Eating most of your calories in one meal can, though, wreak havoc on your metabolic blood markers (such as blood glucose levels and insulin), increase fat gain, inflammation and reduce your day-to-day energy if this eating pattern doesn’t suit you. You’ll know if this is you, and if it is then:
    1. Spread your food intake out across 2-3 meals to lighten the caloric load and see if this makes a difference to your energy or other more objective markers mentioned above.
    2. Remember you’re still a rockstar even if you have to eat more often.
  3. You’ve got a high intake of dairy or nuts. Some, especially women, are not suited to high amounts of dairy or nuts, and when the begin to include more of these foods – ones they’ve avoided for years due to their fat content – they have a weight loss stall they can’t move past or, worse, they begin to store fat around their middle. While some suggest cheese is a food akin to crack, research investigating the addictive properties of the protein in cheese have not found this to be the case. Of course, if you personally can’t stop at one slice and find you’re eating the block, then perhaps it is for you. Nuts can also be trigger foods for some people, and they find it difficult to stop once they’ve started eating them. Ditto with a jar of peanut butter. What to do?
    1. Omit dairy for 30 days – sometimes it’s not the dairy per se, it’s the amounts that you’re eating it in that need to change. Removing it entirely will allow you to change your habits and then reintroduce it.
    2. Omit nuts and/or nut butter as per above in #6a.
    3. Swap snacks to those that are predominantly protein-based rather than fat based – despite the satiating effects of fat, for some, it’s just not like having protein. A hardboiled egg or some leftover chicken wrapped in lettuce or nori sheets (my current obsession) may satisfy you more.
  4. Genetically this isn’t the diet for you. If metabolic markers such as cholesterol, blood sugar or inflammatory factors go skewiff then it could be the LCHF approach doesn’t suit you. Genetic variation in the ApoE gene (ApoE4) is associated with LDL cholesterol not being recycled very well, and therefore it’s more likely to hang around the bloodstream and increase the chances of it becoming either oxidised or being transformed into smaller LDL particles, both highly atherogenic. Variants in the gene FTO can increase risk of obesity in the context of a high saturated fat and low polyunsaturated fat intake and may increase risk of high blood sugar and diabetes in individuals already overfat. The PPAR genes plays a role in ketogenesis (the oxidation of fat for energy) and storage of fat by activating genes associated with fatty acid transport and metabolism. Variants of this gene (particularly PPARa and PPARg ) are associated with increased risk of high triglycerides, total small dense LDL cholesterol and type 2 diabetes in the context of high saturated fat to polyunsaturated fat intake. Further, individual glycemic (blood sugar responses) vary considerably for the same amount of carbohydrate in food, suggesting there are a lot of factors to consider when determining the best diet for you (such as genetics, gut microbiome, activity level, stress etc), not just its macronutrient content. How to figure out if LCHF is not the diet for you? A few things to consider:
    1. Are you losing weight? If so, then wait until your weight stabilises and then retest your numbers – your body recycles triglycerides that are released from adipose (fat) tissue, therefore your triglyceride levels can appear high, but it is transient.
    2. Don’t get your cholesterol levels measured if injured, if you haven’t slept properly or you’ve been under significant stress. Cholesterol levels can change easily based on environmental triggers.
    3. Some people notice their cholesterol increases specifically in response to dairy fat, others to coconut fat – experiment for 6-12 weeks by dropping these out of your diet and get your cholesterol levels retested to see if this brings a drop in your numbers. Replace it with foods that have a more balanced fatty acid profile (such as lard or beef tallow) and foods high in monounsaturated fat or omega 3 fats, such as avocadoes, olive oil, nuts, seeds, salmon, mackerel, sardines.
    4. Here’s one I prepared earlier (and by ‘one’, I mean, ‘post on reducing your cholesterol naturally’. And by ‘naturally’ I mean ‘without Flora Pro Activ’).
    5. Get more in-depth testing of your cardiovascular disease risk profile – cholesterol is one measure and possibly not the most important one. CRP, fibrinogen, LDL particle size, number, oxidation and patterning can all give you more information than the run-of-the-mill lab test can. Contact me as I can help you arrange this testing which, for the most part, your doc might not even be aware of.
    6. Consider getting tested to find out your genetic predisposition (either through your doctor, or I can assist via Fitgenes gene testing).
    7. Consider dropping your fat intake, upping your protein intake and perhaps your carbohydrate intake too – ala the Zone diet approach. Despite its gimmicky name, it’s proven itself to be very effective for blood sugar stabilisation and blood cholesterol management. Some people just aren’t meant to eat a higher fat diet.
  5. You’ve got an intolerance you didn’t realise you had. Going LCHF means, for many, significantly increasing fat content in the diet from the obvious choices: cheese, nuts, seeds, avocados and coconut products. However, while these are awesome in terms of the nutrients they deliver, they can cause digestive issues in a number of people. Avocado, coconut, nuts and seeds are moderate-high in FODMAPs – a type of carbohydrate that can cause bloating, abdominal pain and other irritable bowel symptoms in many people. Further, the inclusion of larger amounts of cream, cheese or full fat yoghurt can be problematic due to an intolerance to the dairy protein or fat which can result in similar IBS in susceptible people. If you’ve been following a low-fat diet for many years, enzymes that help digest the fat and protein may be downregulated, so your body might not cope with the additional amounts. Sometimes it is a matter of backing down and building up, and sometimes it is that these foods just don’t agree with you. What to do? One of these tips may help:
    1. Follow a lower FODMAP approach to see if removing these foods settles down your discomfort. Doing this for at least 21 days and reintroducing a different food one at a time can pinpoint which one in particular might not agree with you.
    2. Introduce fermented foods as per #3e above to re-establish healthy bacteria in your gut.
    3. Replace dairy fat for alternative fat choices: nuts, seeds, avocado, coconut oil, beef tallow, lard.
    4. Ensure you chew your food properly at each meal to break it down, include lemon juice in water in the morning, and apple cider vinegar with meals to stimulate your digestive system, and consider ox bile supplement or a digestive enzyme that has lipase and/or pepsin enzymes to help you break down the fats and proteins.
  6. You’ve upped your alcohol intake because red wine and white spirits are “allowed” on LCHF. This might not even be intentional, but dropping your carbohydrate intake can lead to increased alcohol cravings, especially if your fat intake is too low, or your food intake is too low, or your stress levels are chronically too high. Or perhaps, you enjoy a moderate amount of alcohol but are continuing to gain weight on the LCHF diet.
    1. Be honest about how much you are drinking. Regularly consuming a ‘large’ as opposed to a ‘standard’ pour at the pub? Cracking open a bottle one night and then drinking to finish it off? Your plan to be alcohol free during the week has reduced to being alcohol free Monday – Wednesday? Evaluate if this is a problem for you … or not!
    2. Go alcohol free 5 nights a week, and enjoy a glass of whatever you fancy on the other nights. Ideally not those lolly water vodka mixes, but if you don’t like red wine, then choose something else. It’s not a deal breaker.
    3. Eat enough during the day so you’re not craving alcohol in the evening. This may mean including some additional starchy carbohydrate in your lunch meal – it doesn’t mean you’re not ‘low carb’ – as that in itself is a spectrum. This can really offset your cravings. Try it for 14 days to see if there is an effect.
    4. Lighten the load by choosing to have a low-fat meal if you drink. Old Skool 90s ‘dieting’ approach – those fat calories will only be missed by your adipose tissue, which is where they will be directed to when consumed with alcohol (which is processed first and foremost).
    5. Drink to ensure you are hydrated before you have your first alcoholic drink. This is like 101 really – we always drink more when we are thirsty, and then when we drink more, we become uninhibited and then all hell can break loose, right?
  7. Food timing: If you’re beginning your day with breakfast at 7am and winding down with a cup of tea and some dark chocolate at 10pm, you may be doing yourself a disservice. Eating over a time period of more than 12 hours can be deleterious to health. Recent research has found that restricting the eating period to 12 hours or less can improve insulin resistance and glucose tolerance, and reduce breast cancer risk even when the calories remain the same. Anything you consume that requires processing of any sort by the liver – including black coffee or herbal teas – will begin the metabolic process. When we eat is also important as our appetite hormones are on a circadian rhythm (food being an important signalling molecule for hormones), and eating late at night – even if overall eating window is short – can be problematic for your liver. The benefits derived from intermittent fasting (such as these) can still be realised if your version of fasting includes coffee in the morning, however it appears actual fasting (nothing but water) for at least 12 hours is most beneficial for metabolic health.
    1. Try to keep within a 12 hour window for consuming anything other than water. If you struggle with remembering to do this, there are apps that can help. It’s not as hard as it might seem – if you have breakfast at 7.30am and are done eating by 7.30pm then you’ve nailed it.
  8. You’ve focused entirely on diet without giving pause to consider other aspects of your lifestyle that contribute to your wellbeing. Lack of sleep, chronically elevated stress levels, over or under activity can all contribute to some of the common complaints people attribute to diet which have nothing to do with the food.
    1. Evaluate your sleep – are you getting to bed at a reasonable hour? Able to sleep through the night with ease? Feel refreshed waking up?
    2. Evaluate your physical activity – are you doing enough? Are you doing too much?
    3. Evaluate your stress levels – are you trying to do too much? Feeling overwhelmed? Or conversely is there not enough stress to keep you stimulated and motivated?

Of course these factors contribute to how your body responds to the food, but it isn’t the food per se. As I said last week, this isn’t a definitive list, however if any of these resonate with you then try some of the ideas I’ve listed, or enlist the help of someone like me to guide you to the best approach for you.

PS: I have organised a few talks over the next couple of months to talk about making a real food (aka LCHF) approach work for you. At the moment I have:

LCHF…why isn’t it working for me? (Part 1)

It’s about this time of year that I start seeing people come through my doors needing some minor (or major) tweaks to their LCHF eating approach. There are usually one of two scenarios.

Scenario #1: When they embarked on LCHF they saw ALL of the benefits they heard about, effortlessly shedding body fat, boundless energy (in training and afterwards), improvement in skin tone, hair condition, sleep and digestive problems. But lately the opposite is true. Despite seemingly nailing this LCHF lifestyle, they’ve noticed they are lacking energy, gaining weight (especially around the middle), latest blood tests have seen their cholesterol levels have shot up (and perhaps triglycerides), they are unable to sleep… … yet if anything, they’ve instigated (and nailed) the hacks they’ve read to optimise their LCHF eating approach. What gives??

Scenario #2: They’ve given it a good go on their own for the last 5 weeks, following it to the letter and despite this, it’s ‘not working for them.’ Worse, their husband/workmate/training partner has taken to it with ease.

Frustrating, much?

While we are all individual as to what is going to work for us, the LCHF approach is a really good one for most people, most of the time. Despite that, there are small things that can derail your best efforts to improve your diet, so I want to cover off the basic (and more nuanced) reasons people don’t fare well on a LCHF approach, and some tips on how to overcome them. I’ve ended up splitting this post into two parts as it was so long!

  1. Too low carb. The internet is a wonderful and terrible thing – information is everywhere, everyone is an expert and the version of paleo/LCHF/JERF that you’ve adopted based on what others are doing may well be too low carb for you. LCHF is a spectrum, and what is low carb for one person may well be higher carb for someone else – generally speaking, anything up to 200g of carbohydrate/day could be low carb. It all depends on context. I see a lot of people who are trying to stay strictly below 25g of carbohydrate a day – too strict (and unnecessary) for most people. Even Prof Tim Noakes, staunch advocate of a LCHF approach to eating (“banting”) has loosened up on this. The people who really benefit from a diet this low would be those embarking on it for therapeutic reasons: diabetes (both types), epilepsy, cognitive health (Alzheimer’s, for example). That’s not to say that others out there can’t make this level of carbohydrate work for them. But if you’ve noticed fat gain (especially around the middle), irritability, hormone imbalances (such as a missed menstrual period), lack of energy (past the initial phases of the LCHF approach), irregularity of bowel motions, sleeplessness – to name a few symptoms, then you may have gone too low. What to do?
    1. Track your diet for 4-5 days to get an average of the grams of carbohydrate you eat per day. If it’s on the very low end of the scale (less than 50g*, for example), then try adding back in some good quality starch to see if any of your symptoms improve. Don’t be pedantic about vegetables. Really. That includes carrots and tomatoes. To be honest, you don’t have to track your carbs if you’re not a numbers person – but it can be a good way to assess if this really is the problem. Use My Fitness Pal, Cron-o-meter, My Net Diary or Easy Diet Diary as nutritional tracking tools. (If you’re embarking on a lower carb diet, this is a good first step regardless, so you don’t make the jump from 400g a day to 60g a day).
    2. If your carbohydrate intake is in the realm of 80-100g carbohydrate, you may not be too low, it might be more of a timing problem – ensuring you have carbohydrate in the meal after a high intensity (i.e. CrossFit or F45) or long duration exercise session can help improve recovery and alleviate a lot of fatigue/irritability. If you’re struggling with insomnia, then adding in some kumara or potato into your evening meal increases production of precursors to melatonin.
    3. Is it more protein you need? Protein can help keep you fuller for longer, stabilise blood sugars (therefore has implications for focus/energy/concentration), promote recovery and help with sleep. Many people fear protein because of the potential for it to be converted to glucose in the body (via gluconeogenesis). For someone following a LCHF diet this isn’t an issue. Try upping your protein portions by 1/3 – ½ at each meal.
    4. If it’s in the initial phases, then up your intake of sodium – to levels more than you think you need. When we drop the carbohydrate content of the diet, we drop a lot of water stores too (hence a rapid loss on the scales) – this is because for every gram of carbohydrates stored, we store an additional 3g of water. Add salt to your meals, a pinch in your water bottle, make a miso drink or drink bone broth.
  2. Not low carb enough. I see this a lot. People equate carbohydrate to bread, pasta, rice and cereal and don’t think about other foods that are predominantly carbohydrate –fruit, dried fruit, ‘green smoothies’ with a fruit base, bliss balls, natural fruit and nut bars… In addition, many products are promoted as ‘sugar free’ when they contain dried fruit, maple sugar, rice malt syrup or some other type of natural sweetener. This may seem elementary to you, but I know many people are confused by this point. Regardless of what you hear, sugar IS just sugar – that one sugar is lower in fructose doesn’t mean it’s not going to influence your blood sugar levels, it’s likely to affect them more. This has to be my biggest bugbear of the ‘real food’ movement; not that these products contain sugar – but that they are marketed as not. This is no better than being told that Nutrigrain is healthy. We all know that’s not true.
    1. Again, track your numbers (as per above) via a tracking tool. A lower carbohydrate approach is not a fixed number, it’s a spectrum. But if you’re still consuming over 200g a day and not engaging in regular physical activity, then something might need to be tweaked (especially if you’re not seeing the results you’re after).
    2. Get rid of the bliss balls, the dried fruit, the paleo muffin or the smoothie from your favourite juice bar that you thought tasted suspiciously sweet for something ‘green’.
    3. Read the ingredient lists on the packages you buy. Sugar has over 56 different names. You probably don’t need to know them all, but it would be good to have an idea, right?
  3. Too many processed foods or snacks. Even if you’ve found a sweet spot with your macronutrient intake, having too many processed ‘low carb’ snacks can continue to drive your appetite hormones in a way that favours eating more than you need. Leptin is a hormone produced by fat cells that tells the body when we’ve had enough to eat, and is involved in the regulation of calories we burn and body fat that we store. A consequence of being over-fat is high circulating leptin levels in the bloodstream, and the brain stops reading signals sent by leptin that we’ve consumed enough food. Instead, it incorrectly believes that we are starving, thus we feel hungrier. Excess body fat increases Inflammation in the body, and is one of the drivers of leptin resistance, and processed food can drive inflammatory pathways in the body – even low carb processed food. And if you’re not over-fat? Well, vegetable oils and certain additives and preservatives found in these foods can drive inflammatory pathways in the body. In addition, an overabundance of processed flours may cause disruptions to our gut microbiome as they are easily digested, perhaps not even making it to the gut bacteria in our lower digestive tract. This can mean we are starving our good bacteria and instead feeding bacteria that release endotoxins, causing increasing inflammation. This can have a secondary effect of increasing your cholesterol level (see this post here). These foods are created in such a way to send signals to your brain’s pleasure centre and drive your appetite for more food that you just don’t need. One of the benefits of a real food approach (which naturally lowers your carbohydrate intake) is that inflammation reduces, insulin drops, gut bacteria can rebalance and the signalling pathways in the brain that regulate your appetite hormones can begin to normalise.
    1. Get rid of most foods or snacks that come in a package with ingredients you don’t recognise.
    2. Eat real food. Base your snacks around hardboiled eggs, cheese (for the dairy tolerant), vegetables, leftover meat, macadamia nuts, egg muffins.
    3. Drop the nut flours. Just because they’re low carb does not mean it’s a free for all with these processed flours.
    4. Increase foods that help balance out your fatty acid profile: more fatty fish (such as salmon, mackerel, sardines) and (grass fed) meat for omega 3 fats. Consider taking a fish oil or algae omega for those who don’t eat fish – and be picky about the supplement!
    5. Take care of your gut: consider a probiotic for 30-60 days (such as Lifestream Advanced, Inner Health Plus, Syntol or Prescript Assist) to help populate the gut with the good guys, but also keep them fed with fermented foods such as sauerkraut, raw apple cider vinegar, water kefir and an abundance of vegetable fibres.

I’ve got more – quite a bit more actually! – but will post that in Part 2 so as not to risk losing your attention ;-). These are three of the basics that people can get wrong (particularly in the initial phases), and the next post will cover some of the more nuanced reasons, and what you can do to correct them. If you’re not sure whether your LCHF diet is working for you, why not jump on and book a consultation with me? An expert eye can help take the thinking out of it for you and save a lot of stress long term.

*50g still pretty low actually! Again, it’s all context 😉
