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 of 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 over 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 this point 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 manage (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 be 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 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.

Intuitive Approach vs Metabolic Capacity Approach to Sports Nutrition


Your metabolic capacity is an amount of energy that you would benefit from, put to good use, or otherwise expend in a day if it was made available.

As described in the video and elsewhere on my blog, a lot of the time people are restricting to an insufficient amount, not getting anywhere, and are mislead into believing that that amount is their "maintenance" and that since they're not seeing fat loss on that amount, they have no use for any more.

This is incorrect.

You may be restricting to an insufficient level of fueling and your body may have found a way to adapt and manage it's workload on that amount of energy, but the only reason you aren't burning more is because more has not been made available. What we're talking about here is the difference in approach between being interested in an amount that you can restrict to and get by on vs fueling to the amount that you can benefit from.

On an individual basis, we have a couple of options of approaches that might the most appropriate depending on the circumstances. In reality there is a wide grey area and some over lap between the two, and for most people the best strategy will be somewhere in the middle but perhaps leaning a little towards one or the other. Unfortunately, what most people are doing elsewhere is an anorexic approach based continually reducing levels of energy intake while increasing levels of energy expenditure.

Flexible Fueling Towards Intuitive Eating.

All of a sudden I'm wondering to myself, are we talking about an intuitive approach to sports nutrition, or a sports nutrition approach to intuitive eating?

Either way.

A successful approach to intuitive eating will result in simply having consistently appropriate eating habits that meet your nutritional requirements without exceeding your energy requirements. In other words, eating habits that leave you satisfied, but not stuffed. If you run a little late for a meal or a little short on calories, you get a little reminder in the form of hunger signals, and you respond accordingly.

Without repeating too much of literally every other post I ever published and being redundant, the method is simply to calculate a conservative estimate of a barely adequate energy intake, set whatever meal schedule seems most appealing, and plan accordingly with a selection of foods both of the delicious and the nutritious varieties.

Being of conservative estimate of barely adequate, we anticipate that if training is consistent and as proficiency improves, we anticipate that increases will be required, and assess progress and hunger signals for signs that it is time to do so. If they are not forth coming, perhaps we start dropping a few hints to give the body the idea "there is more here if you can use it, just ask".

Flexible Fueling Towards Metabolic Capacity.

For more advanced and elite athletes and in particular for those where a history of eating disorder or body image issues are less of a concern, this approach would entail calculating a conservative estimate of Metabolic Capacity, deciding upon the appropriate increments and the schedule upon which to increase intake to that amount, and then simply following the strategy diligently.

Once that conservative level has been achieved and maintained for a suitable duration, the situation can be assessed with a view towards increasing further still to a less conservative, or even a more adventurous estimate of the greatest amount that the athlete can utilise and benefit from.

Sports Nutrition For Serious Fitness Enthusiasts

Diet culture really has no place in the world of fitness enthusiasts. Your nutritional habits do have to be appropriate at the very least, or more optimal if you are ambitious &/or competitive.

Unfortunately what most people are instructing or advocating on their social media pages is actually an anorexic approach. All of those infographics we've seen lately, instructing people to get into deficit and continually slash intake further and further any time progress stalls while also increasing energy expenditure... literally those are anorexic and bulimic messages and approaches. We must reject them, and we must practice sensible, sustainable and appropriate sports nutrition strategies to actually meet our energy requirements to produce our best athletic performance and condition and our best quality of life.

Calories In, Calories Out; Maintenance or plateau?


A little infographic I whipped up, talking about Calories In / Calories Out, "maintenance" calories and weight loss plateaus.
It is a lot more complicated than people seem to think, too complicated to cover all the basis in a simple infographic but I tried my best.
Conventional thinking seems to be that if your weight is neither increasing nor decreasing, then whatever you happen to be doing now is "your maintenance" level of calorie intake. Whether that is working to / restricting to a particular calorie limit, or otherwise. If you're not losing & not gaining weight you're "at maintenance".
This can be problematic in cases where you have active people who are working to calorie limits and not seeing progress. Whether that is "weight loss progress" per se or whether they are already at around an appropriate goal weight but perhaps not at goal condition. The conventional (lack of) wisdom dictates that if you're not seeing fat loss progress, you're "at maintenance" and need to cut lower to get back into deficit.
Not necessarily so, and in my opinion, observations & experience not even the most likely explanation.
In actual fact, "maintenance" is not some pin point specific amount above which you'd gain weight and below which you'd lose fat. In actual fact there may be quite a wide margin between where (at the higher end of the spectrum) your intake is not high enough to gain weight, but is too high to draw from fat stores, and (at the lower end of the spectrum) your intake is insufficient to facilitate improvements in condition via prioritisation of lean mass, and your productivity & performance at training as well as your Non Exercise Activity Thermogenesis is sacrificed in preference to drawing from fat stores.
Somewhere in between is an optimal range of calories where you can expect improvements in performance, energy & resources to be used to support increases in lean mass (at best) at the expense of fat stores or at least while not adding to them.
TL;DR it's like I've been saying for YEARS now and a few other people are starting to catch up to; you require an adequate but not excessive amount relative to your requirements as primarily determined by your amount of & level of proficiency at training, amongst other things. When you cease to see progress you must assess the situation accordingly rather than just assume that you need to eat less. And you do have options other than "bulk w/ fat gain via calorie surplus" & "cut w/ lean mass loss via increased calorie deficit".
