Once I cut out the carbs, I started sleeping better. Plus, I stopped waking up "hangry". My diet right now is high in fiber and protein, and less than 1200 calories per day -- that's less than 400 calories per meal. No diet sodas or other "diet" drinks, either; not even Gatorade (or anything like that); just water or black coffee.
It's just the old "Eat Less / Exercise More" diet -- no fancy foods or esoteric (and expensive) supplements.
I've lost 15 pounds in about 6 weeks.
