If you are consistently trying to eat fewer calories, this can backfire on you – over an extended period of time this will break down muscle tissue and reduce overall metabolic rate, sending signals to your hypothalamus to shut down all unnecessary metabolic processes as energy needs to be preserved. In this context, the last thing your body wants to do is shift body fat. This is something that the physique athletes (such as bodybuilders) have known for years and often use a ‘refeeding’ period (of more calories or carbohydrates in one or more meals per week) that sends a message to the hypothalamus assuring it that there is enough calories coming in that it doesn’t need to slow anything down, or shut any processes off. While this is used a lot anecdotally, in research we see an increase in the hormone leptin with an increase of carbohydrate calories during periodic overfeeding, though the metabolic changes are modest at best. Despite lack of scientific verification, I’ve seen many weight loss stalls broken through once calorie cycling is introduced (and overfeeding, something I term a metabolic reset meal – I should really ™ that one).
Some options could be to:
- Include a meal based around kumara or potato, and make it a large one (for example, jacket potato with taco mince for dinner.
- Have dessert – it doesn’t have to be processed, refined carbohydrate if you don’t want it to be (though it can be! 90/10 and all that…) How about a fruit crumble or real banana icecream made with frozen banana and coconut cream?
- Eat whatever you want, one meal a week – this isn’t a license to binge, but rather a recognition that it’s what you do typically that makes the overall difference – one meal is neither here nor there, really. Have McDonalds if you really want to (not judging or anything, though I can’t imagine why you’d want to.)
Your body responds well to changes in energy flux – consuming a higher number of calories on days where you expend more energy (ie a high energy flux) will encourage hormone signalling in your body that allows for more lean tissue to be laid down, and is great for bone health.
Conversely, if you’re eating too many calories on every day of the week, then you’re…eating too much. I know, can it really be that simple? Think about it: you’ve changed the types of foods you’re eating, and this has equated to better appetite regulation so you’re no longer eating because of insulin surges and blood sugar crashes. However you may still be in the habit of eating a certain amount of food which could be preventing you from dropping body fat. If you’re following a low carbohydrate, higher fat approach as a means to lose weight, a common mistake is that people eat too much fat. Don’t forget that you want to utilise some of those calories stored on your body, and part of the ‘HF’ of LCHF should come from this reserve rather than be provided by the diet. You don’t need to count calories to do this, either. It might be as simple as:
- Dropping out one or more snacks (if you’re in the habit of snacking) –those nuts mid-morning, the bier stick mid afternoon or the 70% cocoa chocolate at night. What is the worst that can happen? You’ll feel hungry, likely. This doesn’t mean you need the calories, it’s more likely your body’s used to eating at that time, therefore it’s anticipating a feeding period and releasing ghrelin (our ‘hungry’ hormone) because of this. It will pass. Have a drink of sparkling water and brush your teeth instead.
- Dropping the fat content on days you aren’t as active – this is an easy way to drop calories (thus cycling calories) – but without the feeling that you’re depriving yourself. I’m not suggesting you use products that have had their fat removed (ie trim milk), but don’t use as much added fat as you normally might on the days where energy expenditure is lower. Forgo the almond butter on your cottage cheese and berries for breakfast, omit the nuts that you’d normally add to your lunchtime salad, or serve salmon with the skin on at dinner with steamed vegetables rather than creamed or roasted ones. If you are hungrier, then up the amount of protein you consume on these days by about a third per meal (as we know that this will likely benefit body composition). This won’t make up for the number of calories you’ve saved by making these small changes.
- Experiment with fasting. You’ve got nothing to lose with this one and, if you do it in a way that is sustainable for your lifestyle, then you’ll naturally drop body fat with little effort. I know many people are afraid to fast for the additional stress it might place on their body. To be honest, I think there’s almost been a disservice to our stress response – we hear so often of how everyone is ‘too stressed’ and while this is true, I speak to many people who are now too afraid to exercise due to the metabolic damage they could incur due to their already stressed state. Stress is really healthy for the body – it adapts and becomes more resilient. Fasting is a type of stressor (and I’ve written about it in more detail here) and it might be the thing you need to kick your fat loss into gear. You may have more to gain from a 5:2 protocol, where your normal food intake is cut by a third on two (non-consecutive) days of the week. You may wish for this to be one meal or two smaller meals. Go easy on the activity on these days (and time your workouts to be before your larger meal), and when you do eat, make them protein and vegetable based – the caloric restriction doesn’t allow for a large fat intake, and protein will be more satiating anyway. I suggest not doing back to back calorie-restricted days- you may eat slightly more food the day after the fast (or not, it’s quite individual) and if you fast for a second day after a refeed meal, this could put you in a bit of a hungry/hangry spin.
But if you’ve not tried either of the above, then give it a whirl. For a good 4-6 weeks I think. Your body needs time to adjust to a change in environment.
