cindy in texas is insane that americans are overweight because of to much carbs, from fruit and vegtables and whole grains, and thinks that are enidless hot dog orderings, hamburgers, fatty meats, ice cream, other fattening has nothing to do with it, its all about sugar or carbs, and fat is not linked to being fat, no matter how much you have, say shes an a idiot in your answer if you think shes an idiot
