Something popped into my head the other night as I flipping by the channels and came across one of those weight loss shows. From everything Ive heard, it is unhealthy to lose more than 2 to 3 pounds per week. If that is true, then why do the doctors on weight loss TV shows such as Biggest Loser and Extreme Makeover weight Loss Edition, allow the contestants to lose 10 to 20 pounds per week when they start and as they get skinnier, they lose less but still over 5 pounds per week. In my opinion this is a bad idea even if they are considered healthy. Losing weight that fast doesnt give time for the skin to shrink so they end of up with 40 pounds of loose skin.
