Except it doesn't sound like that, it sounds a study to better understand why people are overeating so much, and maybe find some new ways to address the problem other than sticking our fingers in our ears and shouting "STOP EATING SO MUCH!" Everyone knows overeating is the problem, and that if overweight people simply ate less calories than they expended, they wouldn't be overweight. Amazingly, this knowledge has not solved the obesity epidemic, nor does it typically help individuals struggling with obesity.
