You're not engaging with what I wrote. The trouble is with refraining from consuming so many calories. The fact that so many people find this so difficult is proof enough that it is not "simple" in the sense of being easily accomplished, and that environmental factors likely contribute to its difficulty. Thus attention should be focused on discovering and addressing these factors, instead of applying social pressure to the obese to eat less.
