Re: When fasting, are the metabolic changes permanent?

I would be more inclined to believe that it goes back. Thousands of people, including myself, have fasted for long periods of time, losing lots of weight, and then went on to a healthy Diet only to gain a few pounds back. Don't worry about it, if you break the fast properly and then move on to a healthy Diet you will not gain the weight back and your metabolism should balance itself out. There will be no damage done.
