This is mostly western phenomenon, though. There is poverty all around the world, and those people are hardly obese. If you consider what resources you need to grow vegetables and what resources you need to get a steak, the vegetable diet with occasional meat that most poor people in the world consume is obviously cheaper then the diet that poor people in the west consume. I would hazard a guess that obesity in the west is not really caused by poverty but by the policies of countries and fast food and food companies.
