Remember how fascinated we were with The Biggest Loser tv reality show? We cheered their weight loss success and then subsequently mourned as they gained the weight back. In fact, in some instances they gained back more weight than they lost. You may remember when the shocking study was published in 2016 revealing the extreme metabolic adaptation (when your resting metabolic rate is less than predicted) that occurred in the contestants of The Biggest Loser show. After 6 years, their metabolism still hadn't recovered to predicted levels. In fact, the average RMR was almost 500 calories lower than expected!
We mourned for all the weight they gained back of course, but mostly we mourned for our own weight loss experience because if the contestants, with their army of doctors, nutritionists, and psychologists gained the weight back and then some, how are we any different? Why even bother to try to lose weight if weight regain is inevitable? Is weight maintenance after weight loss a hopeless, losing battle?
Nope!
Interestingly, since that discouraging and very publicized 2016 study, many follow-up studies have tried to replicate the same results without much success. The truest thing to say about metabolic adaptions during and after weight loss, especially persistent metabolic adaptation is that we just don't have a lot off answers. But here's what we do know:
Is there any explanation for the extreme metabolic adaptation experienced by the contestants of The Biggest Loser? Nothing definitive, but certainly a lot of speculation. One hypothesis is that the weight loss methods employed on the show were so extreme it permanently wrecked the contestants' metabolisms. Another is that they had so much help and so much structure during the filming of the show that when left to their own devices they were unable to replicate the conditions to maintain weight loss. Both theories probably play into the disappointing weight maintenance results. However, that does not mean your weight loss efforts are doomed. Far from it, by employing long-term, sustainable lifestyle changes YOU can maintain your weight loss.
