i think what bothers me the most is that they emphasize that the contestants consistently lose, no matter what. there's no understanding that weight loss is not linear, and certainly not consistent from week to week. contestants who happen to pause or gain a little bit one week are chastised and accused of cheating... even when they've stuck to the exercise plan and (albeit horrible) diet rules they're given.

it's unfair and unrealistic to expect anyone to continually lose 5-7lbs per week, not to mention unhealthy.
