On fatness, I have never met a fatty (with or without a doctor's note) who avoided sweets, white carbs, restaurant junk, and processed foods, and who did at least a little exercise a couple times a week.
I have sympathy for those who have injuries that prevent them from walking, because it means they don't enjoy (or need) the pleasure of eating much.
I'm convinced that obesity is 80% diet, 19% exercise, and 1% medical luck.
If anyone wants me to believe that “metabolism” or hormones change the laws of science, explain how humans came to extract all nutrition from their food, while the special cases somehow extract more nutrients than there is in food, so they can store it as fat. The reality is that your ailment makes you choose to overeat and not exercise, but you can still choose (no matter how hard) to take control.
Yes, one still chooses how much one eats and can control that and the exercise (or lack of it)
