Capitalism is why people are that fat today.  Corporations put financial profit over any consideration, including health.   Companies put out bad studies to sell food along with funding movements like HAES and the crappy government sponsored dietary guidelines.  The elites want you fat, sick and unhappy so you are constantly looking for the next great product that will cure your problem.  For most, their major problem is actually the consumption of too many calories, but telling people to consume less is not good for business.  Instead they will sell you yet another pointless pill or gadget when doing nothing is what people actually need.
