Those are ridiculous!!! Ahhhh!!! It would be interesting to see what diets of today end up on there...I can think of a few...
The worst diet I have ever been on (which I DON'T recommend!) was the 2-4-6-8 diet. It was extreme calorie cycling with 200 calories the first day (yes, DAY), then 400 the next, then 600, 800, and back around to 200. Yes, of course I lost weight, but it totally wasn't healthy! Those 200 cal days were painful. I remember on the 800 calorie days I was always baffled as to how I could possibly eat that many calories - LOL!
It's amazing what people will do to be thin, huh? I think I'll take healthy and fit over skinny and miserable any day!
