Lots of protein. Which, of course, could be meat, but also tofu/soy, nut butters and loads of nuts, eggs, CHEESE, various other dairy, etc. And also fish, though I don't eat fish.

I've never looked into the Atkins diet, which is low-carb, too, but apparently that's completely wack and puts people into ketosis. You eat basically no carbs/no sugar/no alcohol/no (or minimal) caffeine for two weeks, all the while eating tons of protein, "good" fats and greens to the point that you really don't want to think about food any more.

Inadvertently, due to the carb (bread) restriction, I discovered that I am wheat/gluten-sensitive and the never-flat stomach I've always had is...now flat, since I'm not trying to digest things I apparently don't really want to digest.

So, besides the weight loss, I'm feeling better overall and have more energy (after the first two weeks of near-constant sleep, which seems to be specific to me and my former all-sugar diet). My biggest problem now is trying to remember to eat and stay in the regular-meals habit, because the weight loss picks up again if I eat more food.

Oh, and after the first two weeks, you are still supposed to watch carbs and sugars, but you are encouraged to drink red wine and you can have chocolate and...

yeah, I'm a goddamn zealot.
