A lot of lean protein and vegetables; eggs (3 egg-whites + 1 whole egg is a common combination for me), chicken, fish, broccoli, etc. I wasn't trying for low-carb, but low-carb made it easier to stave off cravings. I was paying attention to calories more than anything else.

I do drink, however, straight liquor. Rarely to excess, but also rarely fewer than 2 drinks (almost always 2-3 drinks an evening).
