Their poor memory along with not having even a vague idea of nutrition and caloric intake makes then retarded. I wish I had the money and time to make a fat challenge. Have someone bet a $1000 or some shit that they defy physics and have found a way to create energy out of thin air.  The bet being that they will not lose weight eating less. Go beyond secret eaters and actively follow someone all day every day for a week closely controlling every calorie they stuff into their lard bodies. End of the week if they lose weight they donate to a charity.
