[quote=Anonymous][quote=Anonymous]Back in the day in the diet world you always heard about messing up your metabolism if you fasted and about losing weight too quickly. Is that not a concern any longer with IF?[/quote]

There really is no evidence that the speed at which you lose weight, or how you do it, has anything to do with messing your metabolism. What DOES change your metabolism is getting fat, and staying fat. Gaining and losing the same 10 pounds on 6 monthly cycle is probably fine, but gaining 30 lbs and keeping it on for 10 years and then trying to lose it is going to be hard, because your metabolism had adjusted to the weight. As you try to lose weight your metabolism slows to hold on to the fat. The more you lose, the more your body slows. This is what happens to all people who lose a significant amount of weight after being heavy for a time. But it has nothing to do with fasting or losing too quickly. In fact, there is evidence that you should lose quickly because people lose motivation to lose slowly, and give up. There are long term studies of people who have maintained weight loss (I am in one of those studies) and they find that losing weight isn't really the issue - any diet that works for you is fine - the issue is maintaining. That is even harder.[/quote]
