I follow a very simple diet, which is similar to a diabetic diet and from what I've, seen, weight watchers. It is based on portion sizes of any food. It is easy to follow, and was easy to stick to. Took me from 208 lbs down to 125. As of late, I'm trying to introduce new foods & methods, such as protein drinks, carb cycling, and such. The only reason for this is to try to put healthier food into my diet, not just calories.
