There is absolutely no doubt that calories are cheaper and easier to come by than ever before in history. Our 'rubenesque' bodies would be enviable by the peasants of the old countries. Only nobility would have the life of leisure and access to excessive calories to get as fat anyone can today. Inuit (eskimos) have traditionally eaten very fatty whale blubber as it is high calorie, yet didn't become obese. Why? They were active and whales weren't easy to come by. Now they can get all the calories they need to exist from one Big Mac meal without having to work up a sweat.

Problem is several fold: not all calories are nutritious. if there is a glut of available calories self restraint becomes a huge factor. fruit and veggies are still more expensive than processed carb calories. we don't have to do any physical labour to get our food. genetic disposition. LIFESTYLE.
