Man, I wish their were some nefarious conspiracy involved. That would make me feel a little better about the state of the human race. I think it is all gluttony and lazyness. The closest thing you have to a pushing for obesity is the profit driven junk food industry and fat acceptance. I guess it would be a good plan for the higher ups, fatties can't effectively revolt or fight back. The hole in this logic is the people at the top are also fat fucks.
