If people lose a lot of weight, do their bodies fight to regain it?
Sixteen obese contestants on NBC’s “The Biggest Loser” lost an average of 128 pounds after an intensive seven months of dieting and exercise in 2009. That amounted to shedding an average of 39 percent of their body weight.
Could they keep that weight off? Researchers at the National Institutes of Health set out to find out from the 14 contestants who agreed to be studied.
