Why do you gain back so fast?
I've been really curious about this... also kind of nervous. I keep hearing how when you stop this diet, you gain back A LOT and fast. Some have said "Well yeah, if you stop eating healthy and start your old habits, it will come back". But I remember someone saying they stopped and went to Weight Watchers, so still eating healthy, just not low cal/fat/carb.
What is the difference in stopping IP and stopping any other diet that makes the weight come back on so fast? I do intend to go through all phases, but it terrifies me that I may lose weight and a bad day or week could royally screw me and set me back so much.
