Well of course they did. That show had them losing a POUND PER DAY - that's insane. You'll never be able to maintain that kind of metabolism and calorie burn, it would be a full time job and then some. I spent the last year losing a pound per week and that was challenging enough. I still can't touch more than 2000 calories per day or I will gain weight and I run every morning.
