You don't have to eat EVERYTHING they give you on the plate in ONE eating.
When I go to a restaurant, they are usually giving me anywhere between 3-4 servings.
I eat one serving, and get the rest to go along with regularly exercising.
I used to be obese myself, and I lost all my weight by just watching my portions and how many calories I was in taking along with exercising regularly which just consisted of me doing some pushups/situps and walks.
The problem is people have become too lazy. That is their problem and not HFCS. What's next, legislating the portions of food because people are too dumb to do it themselves?
