There was a recent N.Y. Times article about several former “Biggest Loser” contestants who have gained most or all of their weight back. After some tests, it was found that many of them had a slower metabolic rate than would be expected from a person of their current size.
This has many wondering if the extreme approach taken by the show is the cause of the metabolic slow down. Is it possible that the their weight set point in the brain hasn’t caught up with the body and their bodies are trying to regain the weight for fear of starving? This MAY be a factor but for now, even the doctors aren’t sure what has the metabolisms of many of these “Biggest Losers” as much 200 to 500 calories a day slower than they should be.
