I'm trying Tim Ferris' "slow carb diet" from his "4 Hour Body" book. I can only eat legumes (for carbs), vegetables and protean plus I get to binge on whatever I want 1 day a week (fruits, milk/lactose, grains ect..). I feel great and I've been losing weight (10lbs in 3 weeks with no exercise or portion/calorie restrictions so far). It's a little tough to do this diet as a vegetarian but it's much easier than attempting to balance eating grains and dairy (& fructose) while trying to lose weight or trying to fall asleep when your stomach is growling.
How is the section on the sleep diet in that book? I was curious about that.
