Has anyone ever heard of this or tried it? If so, I was just wondering what you thought about it or if you found it to be a good thing to do. I was reading about it somewhere - it's where you do a 24 hour water fast, and then for 2 -3 days, you pick one food and eat lots and lots and lots of it - almost reminds of doing the egg fast...and then after those 3 days, you see where you are and whether what you ate was a feel good/lose weight food or perhaps, it was a feel lousy/gain weight food...I just thought it was interesting to read about this...I guess that could be a good way of finding out what works for someone and what doesn't...I'm not so sure I'd want to try it but just wanted to know what other people might have thought about it. One lady that did that said she couldn't eat mayonaise without it making her feel lousy...I wonder, is that all she ate during those 2 -3 days? Eeek!
