Interrupted Energy Restriction Strategy

Interrupted Energy Restriction Strategy

Brand new for 2018, a new variation on the Flexible Fueling system inspired by the recent MATADOR (Minimising Adaptive Thermogenesis And Deactivating Obesity Rebound) Study showing that greater weight loss results were achieved with a “two weeks on, two weeks off” approach to dieting compared to continuous energy restriction.

I want to try to skim over a couple of things that have been covered previously and get on to what’s new. My Flexible Fueling approach (in fact, even before I started calling it Flexible Fueling) has always been about getting people OUT of that restrictive, further and further into deficit approach to IIFYM and getting them confidently enjoying a variety the delicious & nutritious foods that suit & appeal to them, to a total energy provision that is adequate, but not excessive.

Flexible Fueling Towards Intuitive Eating

I covered this in more detail recently, but suffice it to say that for many people it’s enough just to get out of dieting, practice regular eating habits to ensure that they meet at least a conservative estimate of their minimum requirements, leaving a reasonable margin for error or variance so that they don’t have to feel anxious about a social engagement where they may indulge a little… and to understand that as this is a conservative estimate of minimal requirements, before long they’re likely to experience some hunger signals, which they should respond to accordingly with an increase to a more appropriate level of daily energy intake.

Flexible Fueling Towards Metabolic Capacity

My experience as a professional coach is that in the vast majority of cases, people’s problems stem from attempting to restrict to an insufficient level of energy intake relative to their requirements. In the case of more experienced, more proficient, serious fitness enthusiasts and competitive athletes this is a serious problem. Particularly with a younger, taller, more active client with a more advanced level of prowess at training it is imperative to increase steadily towards a target representing the highest level of energy intake that can be put to good use and produce a benefit in terms of athletic performance and condition.

This does not mean a “bulk and cut” strategy.

Serious fitness enthusiasts and competitive athletes as described above have a high energy requirement and potentially massive capacity for energy flux AKA the amount of energy that could be expended or otherwise utilised. As you increase towards this amount, a leaner and more athletic condition will be the result.

If you’ve been following me for a while you’ll know all of this already, and you’ll know it’s what I’ve been talking about for years and everyone else is slowly starting to catch up to, including a bunch of suck ass motherfuckers who’ve argued with me in the past. PROLONGED & EXCESSIVE LEVELS OF RESTRICTION CAN ONLY BACKFIRE AND CANNOT RESULT IN MAINTENANCE OF A LEAN ATHLETIC CONDITION. Rather, that sort of nonsense is only conducive to a regression in physical condition and the development of an eating disorder.

So much for the “skim”. Let’s cut to it.

The Flexible Fueling Punctuated Periodisation Protocol

What we’re doing here is inspired by the MATADOR study, but it’s a little different and also I don’t like to have anything to do with the notion of “restriction”, so I had to come up with a cool name of my own for this variation on the strategy.

Refer to the graphic below, and I’ll explain how it works.

For the first two weeks, we start at the most conservative estimate of absolute minimum requirement. Often this is still more than the amounts people are attempting to work with when they come to me. I drew this as a curve, as we’re likely to find that it does in fact turn out to be overly conservative and that we need to come a little higher, towards a more reasonable, more workable reflection of our minimum requirement.

For the next two weeks, we work to a conservative estimate of Metabolic Capacity.

In theory vs in practice.

In theory, so long as you’re in caloric deficit¬†your body will draw upon fat stores to make up the difference, right? And the further into deficit, the more fat loss, right? And if you’re not seeing fat loss, you’re not in deficit, right?

Bull. Shit.

Real quick… what a lot of these fucking imbeciles out there don’t quite have the brain capacity to grasp is that there is a difference between for example a 90kg male aspiring body builder who has just done a “bulk” on say 3500 cals per day, and a female athlete on 1400 calories per day or an overweight mature age female with a decades long history of extreme crash dieting. The male could cut to 2500 calories and see fat loss due to being “in deficit” and may find at some point that he needs to cut further to keep leaning out. That’s not how I’d do it because I’m smarter than that, but that’s why they think “if you’re in deficit you lose fat, when you’re not losing fat cut further into deficit”. The female athlete can’t possibly cut any lower and should never have been instructed to cut that low to begin with, YOU GET ME?

So, in pursuit of your goals you need more than just “restrict, restrict further and keep on restricting indefinitely until you hate your fucken life”. You need a system where you work to intelligently calculated targets, and assess your response to those targets until you find what feels right and works right for you, allowing you to enjoy life and enjoy your best and most sustainable results from training.

Assessing the response and revising the strategy.

In theory you should see fat loss and therefore weight loss in that two week period at minimal intake. Interestingly though, some people will not see weight loss at that phase, but will see fat loss during the next two weeks while working to higher intakes. In which case, the question is whether the period of restriction is unproductive or whether it is necessary as the fat loss is a response to coming out of deficit. There’s only one way to find out. If the period of restriction proves unproductive then it makes sense to find the lowest productive level of intake and consider that the new minimum.

If there is no fat loss at either level, you may decide to repeat the period and give it a little longer to see if it kicks in. Or you may logically conclude that since you can’t go any lower, and since a conservative estimate of the most you could benefit from didn’t do the job, you can only conclude that intake is still not high enough and a further increase to a less conservative estimate is required, as indicated on the chart at Week 7 & 8. In fact… if fat loss is apparent I’d still be likely to conclude that our conservative estimate is indeed quite conservative and I’d be optimistic that an increase to a less conservative level will prove productive.

At the very worst if we do overshoot that maximum level of intake and see an increase in weight beyond what would be explained simply by having more food passing through the digestive system, we have two weeks back at minimal intakes just around the corner that will resolve that, and we know to set our higher target more conservatively next time.

More likely though especially in the younger, the taller, and especially the more active people with a higher level of athletic prowess, everything works out better than expected and by the third cycle of the strategy we’re confident and enthusiastic to get more adventurous with our higher targets.

Beyond Twelve Weeks

Having worked to different levels we’ll have learned what’s the least we can expect to last a few days or a week on, what’s the most we can currently put to use while producing a leaner condition, and what’s the optimal level of fueling relative to our requirements. We can then make an educated decision how best to proceed, either eating intuitively in accordance with our new habits and the healthy appetite we’ve developed, or by working to an optimal target for an extended period, or by continuing with the Punctuated Periodisation Protocol.

It’s about enjoying life, enjoying the intellectual stimulation of working to a strategy, enjoying the physical stimulation of training, and enjoying the best and most sustainable results in athletic performance and condition.

Of course… such a complex and convoluted approach is not for everyone, which is why Flexible Fueling works on a spectrum between the “towards intuitive” to the “towards capacity” approaches, with this being somewhere in between. And it goes without saying that there’s only ONE person capable of coaching this approach. Other people calling themselves “IIFYM” or “Flexible Dieting” guys and girls can’t even begin to grasp this stuff. They literally just think “keep eating less, you must be lying to me and eating more than you say you are” is what passes for coaching.
