Body for Life. Six small meals a day, protein and carb. Portion is the size of your fist or your palm. Food choices from list of usual suspects, incl. boneless chicken, lean meat, fish, etc., egg whites (I eat yolks anyway), veggies, unbuttered baked potato, etc. The book pushes a brand of meal replacement protein shakes, which is not necessary. BBQ, pizza, mac and cheese, choc. layer cake, all verboten. Occ. glass of wine is ok. Plan also has you do workouts, weight days alternating with cardio days, six days/week. But seventh day is free day–eat whatever your want, skip the workout.
I have lost tons of weight on this plan, but I really love food, and when I stray, the weight comes right back.
