Why Is Recomping So Much Better than Normal Weight Loss?

Why Is Recomping So Much Better than Normal Weight Loss?

Last week we talked about the potential dangers of losing weight without exercise and the dreaded Fat Overshoot. If you missed it, you can check that out HERE!

Furthermore, it looks like the more muscle you lose on a diet the more likely you may be to experience weight regain after the diet [1].

What's a solution to this mess?

Recomping or gaining muscle while simultaneously losing body fat.

This week we are going to cover why Recomping is potentially so much better than more normal weight-loss philosophies.

With Recomping, because we are gaining muscle mass while shredding body fat we likely don’t get the more prototypical downsides of weight loss:

  • muscle loss
  • a decrease in resting metabolic rate (RMR)
  • an increase in muscular efficiency (muscles burn fewer calories for the same amount of work)
  • and a potential Fat Overshoot.

Recomping potentially allows us to maintain or even increase our RMR while losing significant amounts of body fat [2-5].

For example, given that muscle burns about three times more calories per pound compared to adipose tissue [6], if for every three pounds of body fat you lost, you gained one pound of muscle your RMR would theoretically be the same in a significant body fat reduced state. (*These are almost the exact body composition results that were found in the famous Longland et al. Recomp study [7]).

Although these small potential changes in RMR are hard to estimate in practice and probably not of much practical importance to those using counting methodologies around food such as macros [8], I would wager that your total daily energy expenditure or the number of calories you burn in a day may even INCREASE with Recomping [9, 10].

In theory, this would mean that people could potentially eat MORE calories at a lower body weight, and given that an increase in appetite is one of the largest potential contributors to weight regain [11, 12] this could be monumentally important for successful long-term weight loss!

Although it isn’t a recomp study, as an example Bryner et al. [5] found that even in a severe energy deficit without sufficient protein, when subjects performed a decent resistance training regimen three days a week for 12 weeks they lost 31.6 lbs of fat, maintained their lean body mass, and had a 63 calorie jump in their resting metabolic rate after 12 weeks.

They also got 23 to 48% stronger on all the tested lifts.

Whereas, the aerobic exercise and diet group lost 28.2 pounds of fat, lost 9.0 pounds of lean body mass, and their resting metabolic rate decreased by 211 calories!

Pure and simple, friends don't let friends lose significant amounts of muscle on a diet and if you are looking to lose body fat and keep it off - Recomping is likely your best play.

TL; DR - Recomping decreases and maybe even eliminates the majority of the downsides of conventional weight-loss strategies. Given the preponderance of data showing the multitude of positive effects, in my opinion, friends don’t let friends diet without resistance training and every study showing a significant body recomposition effect has had a resistance training intervention.
