The do the Michael Thurmond 6 week makeover. It does drop weight quickly, but has a fairly low tolerance rate for the long term. I tried it a year ago and lost 20 lbs very quickly (about 8 weeks I think) but watched their forum for posters just dropping out like flies. It's basically a moderate protein, moderate carb, ZERO added fat, ZERO added salt, ZERO added sugar diet. With the zero fat and salt it may possibly be the blandest WOE you have ever encountered.

I lasted about 9 weeks then my body began screaming for relief.

Not once since I began Atkins have I craved anything very much. It's the tastiest food I've eaten for years. I'm losing more slowly but I could eat like this forever
