Re: can one keep the weight loss post fast?

The reason you gain all the weight back post-fast is because you don't have a proper diet pre-fast. Therefore, after the fast you don't know how, or what, to eat.
I'd suggest you eat a simple cooked Vegetarian Diet to start. You may, over time, improve that to a cooked Vegan Diet, adding more and more raw foods as the years go by. The ultimate diet is a 100% Raw Vegan Diet (IMO). There is much controversy on Diet. Find one that suits you, and stick to it.
As we all know, food has strong addictive powers. Very few escape its hold......WY
P.S. Everything I've said here has been directed to myself. But maybe you can use some of it.
