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.
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!
- 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?
- 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).
- 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.
- 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.
- 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.
- 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.
- 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).
- 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’.
- 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?
- 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.
- Get rid of most foods or snacks that come in a package with ingredients you don’t recognise.
- Eat real food. Base your snacks around hardboiled eggs, cheese (for the dairy tolerant), vegetables, leftover meat, macadamia nuts, egg muffins.
- Drop the nut flours. Just because they’re low carb does not mean it’s a free for all with these processed flours.
- 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!
- 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 😉
