The physical transformation experienced by contestants on The Biggest Loser is nothing short of dramatic.
In a matter of months, their diet and levels of physical exercise are completely overhauled, generally resulting in the loss of a large proportion of their body weight (and many, many tears shed against a heart-wrenching soundtrack).
There’s no doubt this makes for compelling television — The Biggest Loser never fails to be a watercooler talking point — but you have to wonder what it does to the contestants’ bodies in the long-term.
A number of former TBL stars have struggled to maintain the weight they ended the show on, and according to a new research, this is not simply due to a lack of willpower, or the fact that they no longer have access to 24/7 trainers. It largely comes down to how the program impacted their metabolisms.
In a study published in the journal Obesity this week, a team of researchers examined 14 contestants from The Biggest Loser‘s eighth US season to see what had happened to their bodies six years after the show.
