If you ask many GPs in the west they will tell you that a majority of illnesses they address are related to weight and diet. With an aging, increasingly overweight adult population alongside a sharp rise in child obesity come big consequences for health care over the next half century.
Im not saying its an easy task you can just throw money at, but if trends continue as they are now the health and economic impact on society will be huge.
Bar some sort of national catastrophe (for e.g. war, famine, disease) is it a crazy idea to think we could see a reduction in obesity levels? Are we simply resigned to the fact that we will just get bigger and bigger in the future?
