I've often wondered if some of their contestants weren't going to fall over dead after being forced to do heavy exercise when just beginning to diet, while still 200-300 lbs overweight.

Have you heard that the first contestant (forgot her name) has gained back so much that she is obese again? They gave her her own show and I would watch as she instructed them to cook low-fat, high carb and think to myself, that won't last.....
