People who are over weight look at food in a differnt way than skinny people. Food for fat people is VERY much like drugs for a user. The mental ties to the food are very hard to over come. Must of the time one can pull enough will power together for a short period however between your mind craveing things, tv comm., a busy work schedule, and other things it is very hard to stay on a diet plan. For fat people to "just don't eat that much" is like if we told you to "just don't eat at all" becouse it is that hard to over come.
Now on a second note I do get bothered with the people that look for "The pill". People think that they will be able to take a pill and puff they are thin. They think they will not have to earn nutrion(sp?) and over come there eating disorder.
