The first thing to understand is that your body responds to food metabolically. A short fast is also responded to metabolically. We're not talking starvation. 15 hours without food is all it may take and you can be asleep for part of that. Don't do it unless it's easy and pleasurable to do it. You have to be ready. It helps if your body is adapted enough that it can handle long periods of time in a state of ketosis, or that it can go in and out of ketosis easily, because that's what the fast will do. Put you in ketosis.

The time off from eating will rev up my metabolism because hormones that don't normally get a chance to fire while I'm regularly fed get a chance to do their thing. I learned a lot of Dr. Eade's website here, especially reading the comments:

One thing I was really impressed with reading the comments was how many women, especially older ones like me, had great success with this kind of fasting. Whereas almost everywhere you read from older women having trouble losing weight on primal diets, you read lots of reports of success in losing weight and improved health on topics regarding intermittent fasting.
It's my plan to do this on purpose only once a week. Not every day. Not grit my teeth through it. If I'm hungry I will break the fast. The point is to feel great, not suffer.
Mark's got some stuff on it too but I haven't read it all yet.
