How Caloric Over-Restriction Makes Binge Eating Inevitable.

Just a little something I’ve been working on.

Here’s the thing with caloric deficits and binge eating. 

I put these numbers together as a hypothetical case study on a female of average height and a certain undisclosed age. Suffice it to say, if you’re taller than average these targets would be overly conservative. If you’re younger; also overly conservative. But the factor that really makes the biggest difference and which tends to be entirely neglected by most people writing about CI/CO and IIFYM style approaches is level of proficiency and productivity at training.

So, for a beginner who has a fat loss goal, we would start out in deficit. According to a lot of social media posts and infographics, all that matters is that you are “in deficit”, and so long as you are in deficit you lose body fat, and if you’re not losing body fat you’re not in deficit. 

Well, that's actually garbage.

Somewhat insufficient and unsustainable levels of energy intake can be an appropriate strategic move at times, but only for short periods and with the understanding that is not really enough, and the anticipation that an increase will be required within a predicted duration of time.

So in this example the client is instructed to begin at 1400 calories which should be considered an overly conservative estimate of her requirements. As part of an intelligent strategy, the reason for doing so might be to learn to recognise and respond accordingly to hunger signals... however in this case, it is simple caloric restriction in order to be at a significant level of deficit. While the client is told "you'll see fat loss due to being in deficit", this is only half of the truth, and what also happens is that the body adapts by compromising energy expenditure at training, at rest, and at activity outside of training as well.

At a certain point fat loss will cease to occur, and what the client is likely to be told according to the many infographics doing the rounds of late, is that she is "no longer in deficit" and must either cut caloric intake further or increase energy expenditure via extra training sessions or more deliberate activity outside of training. However, at this point all she is really doing is training the body to manage, and for that matter to require this increased level of work load at this level of energy restriction... and this cannot and will not result in improvements in athletic condition.

Now, the further we instruct the client to restrict intake further below this already insufficient level of energy provision, the greater the magnitude of the inevitable binge eating episode that will follow. 

Reiterating & understanding the situation correctly at this point.

This level of restriction will preclude any improvements in lean athletic condition, as the resources are simply not available to recover from and adapt to training, other than with the adaptations necessary to cope with (rather than benefit from) the workload. Since we have attempted to restrict even below that amount, the inevitable binge episode will be of a magnitude to bring average intake to a level that is merely sufficient to do so and maintain weight.

So, this means the client is no longer in deficit?

Nope.

This is a conversation I have had a few too many times, where I'm attempting to explain this situation and citing examples of clients who've been a lot happier and seen major improvements in performance and condition by increasing towards more optimal levels of energy intake in accordance with my instructions. "But Dave, what you don't understand is that she hasn't mentioned that she is binge eating, so that's why she's not in deficit". Wrong you stupid motherfucker. I am well aware that she is binge eating, as that is the problem she has come to me desperate for help with. 

What you can see in the chart above is some estimates of what might be the maximum amount this client could benefit from or otherwise expend on a daily basis at different levels of proficiency at training. The greater your consistency and proficiency at training, the higher the amount you can put to use and benefit from. The more severe the level of restriction on a daily basis, the more mathematically improbable it is that a single (or even a couple of) binge eating episodes on a weekly basis could "erase the deficit" and result in a caloric surplus so as to preclude fat loss.

Rather, the situation is that even taking binge episodes into account, total intake is still only to a level that allows the body to manage / cope with the workload, but not to a level that facilitates improvements in performance and condition. To benefit from training you require a certain level of energy intake and other nutritional resources, in order to recover from and adapt favourably to the level of stress you are subjecting your body to.
