I bet it's half and half. Most people don't realize the problems that come with being overweight till they have carried it a long while. I'm personally a string bean and always have been, but I was pre-diabetic with an A1C of 5.7. I can't say I'm unhappy, but man I wish I could just eat anything I wanted. I severely limit carbs and sugars.... Def happier eating with friends and family.
