Americans got fat because portion sizes and the availability of cheap high calorie density foods increased while levels of physical activity decreased. There is nothing inherantly obesogenic about carbohydrates, indeed most of the worlds population eats a high carb diet without getting fat, so to single out carbs as the sole cause of Americas epidemic levels of obesity is a gross oversimplification of the problem.
