Most people have heard of reverse dieting by now. But for those that don’t know what it means, reverse dieting refers to the process of slowly increasing calories following a prolonged period of low calories (such as a competition prep), when metabolic rate is slightly lower (mostly due to a lower body size). Lots of competitors do this following a competition, but others who have tried to diet for months and/or years on consistently low calories may also aim to reverse diet their way back to a higher maintenance of calories again. The overall aim of reverse dieting is to achieve a relatively higher maintenance intake, so that the individual can eat more food and/or undertake less cardio, on a daily basis. Long-term, this should allow the person to diet down again, without having to diet on such low calories as before.
Does it work?
There are lots of ways to judge whether a reverse diet has been successful or not, some better than others. For me, there are 2 main outcomes:
– Does the person have a better relationship with food?
– Can the person eat a more comfortable and sustainable amount of food without excessive fat gain, compared with dieting?
How do you define success of a reverse diet? You might slowly gain a little muscle, a little fat, and on the outside, avoid a huge ‘rebound’ that we see so frequently in competitors and in those who have undergone a strict calorie restricted diet (Juice diets anyone?). But what about what we don’t see? Those people, they may appear to have found themselves back in a comfortable place, after following a slow reverse, training hard and increasing their calorie intake. But in my experience, and from reading around the area, most people that reverse diet, fail. And I don’t mean that they fail to hit a maintenance without unnecessary weight gain, I mean they fail because mentally, they are in serious trouble. These people tend to be binging behind closed doors. Because they are hungry and goalless. Those people who never had trouble with food before, or perhaps did, and that’s why they found the dieting/tracked intake life in the first place, are now stuck in a binge-starve cycle. Some may develop bulimia. Sound extreme? Absolutely. But unfortunately, it is all too common.
Reverse dieting and your relationship with food
You’ve probably heard people say they have ‘metabolic damage’ after some silly coach put them on an excessively low calorie intake, then they gained loads of weight and said they must have metabolic damage. Or, they’re still on an excessively low intake but just can’t lose weight. The term ‘metabolic damage’ is used to describe the phenomenon that after eating under maintenance calories for a prolonged period, you’ll undergo negative metabolic changes that will lead to a lower resting energy expenditure, even after you’ve gained weight back that you have lost i.e. you will have to consume less calories at the same weight, in order to maintain that weight.
Any change in your metabolic rate is in line with body composition. You know those people who look lean and muscular and can put the food away, the bottomless pit people? Lean body mass has the biggest effect on your metabolic rate. That’s why weight lifting, and improving your muscle mass, is so useful when you’re trying to reduce your body fat.
Lots of research has looked at the phenomenon of metabolic damage, and whether it does even exist. Years and years ago, some crazy people volunteered to starve themselves for 6 months (way harder than a bikini prep I can imagine) as part of the Minnesota starvation experiment. They were then refed and regained their body weight, and alas, there was no reduction in their metabolic rate. You’ll see something similar in anorexia patients – they don’t have any reduction in metabolic rate once recovered. Yes, if you’re lighter and have a lower fat and lean muscle mass, of course your metabolic rate is slower, you have less of the body mass that determines metabolic rate. Put this back on, and it appears your metabolic rate will reestablish itself.
What can happen though, is that if you stay in a super lean state for a long time, this reduction in metabolic rate goes further than just being lower due to lower body mass (adaptive thermogenesis). Hence one of the reasons why you don’t want to stay crazy lean year-round (and it’s also cold. And boring. And your ass is small).
Reverse dieting vs. an immediate return to maintainance
There are people that use ‘reverse dieting’ as a throw away phrase, a phrase of disgust alongside ‘flexible dieting’ (you know the type that swear IIFYM is an excuse for lazy people to eat pop tarts every day), who might go straight back up to maintenance calories after prep, or even a surplus in calories, to ‘make the most of the rebound’ and/or get the most out of their limited time of growth of an off-season. And that’s ok too…
There’s not much to suggest that slowly returning calories to maintenance vs. immediately upping them after prolonged restriction, will result in much difference to your metabolic rate. So if body mass (mostly lean body mass but fat mass too) predominantly set your metabolic rate, why not get there as quickly as possible to get your metabolic rate back there faster?
Competitors: If you revert back to your previous maintenance intake, then remember that it is no longer the same as your previous maintenance i.e. if you consumed 3000 calories pre-prep at 65kg, then you’re a lower body weight and probably lower lean body mass post-prep, so your maintenance is not going to be as high as 3000 anymore. You have to take in to account these changes in your body composition.
What this usually means, is that you start with a more drastic increase in intake back to maintenance after prep (but still maintenance calories as calculated for your now lower body weight), then following this you increase more slowly. Doing this will allow you to maximise your potential for muscle hypertrophy in your limited off season period (a much slower reverse will simply limit your time for growth – focus on your long term goals here).
Now that I’ve decided to take a break from competing, my goals are to gain some muscle mass without gaining huge amounts of fat (I want some, I miss my booty). I also don’t want to track, but for me, I’m aware of the macros in most of my foods, inadvertently. So for me, a slow reverse diet is appropriate. I’ve bumped my calories up to just below maintenance since coming off prep, for me a sustainable amount without making me so hungry that I end up binging (I’ve spoken about this before). I’m roughly aware of my calorie intake, but without tracking I can’t be sure. I’ve done this without my fitness pal daily tracking (I plan to write my next blog on learning to move away from tracking every meal), and without binging 95% of the time. I plan to conservatively increase this intake and remain in a slight surplus in calories, to allow some lean body mass increases (and yes, a little fat). This works for me. I’ve tried a strict tracked reverse diet, and I avoided fat gain, but also minimised muscle gains in my previous off seasons and it took months to make a full week without binging. This has been the fastest that I have ever recovered after competing, so for me, I can judge this to be the most successful ‘post-diet diet’ yet…
