Doesn't obesity preceding the HAES movement prove that HAES couldn't have caused the obesity epidemic? If you found a 50% increase in lung cancer next to major highways, would your solution be to use peer pressure to encourage everyone to take shallower breaths and then berate people for not succumbing to peer pressure? Of course not because it's obvious to us that the cause is environmental and the correct approach is regulation to reduce the cause of the disease. Treating obesity as a public health problem rather than a willpower problem is a) obviously a more sane approach and b) contrary to business interests.
