They probably know they are obese, they don't need other people making it worse for them. I've been mocked about my weight and it hurts so I understand how it feels. I've lost a couple of stone and I like to eat the best I can but still don't want to judge people. I've been through the same stuff. They are still people with feelings. Anyway why do people really care about someone's weight? It's their body, not yours. If you are fit and healthy, good for you. Some people are dealing with their inner demons. You don't have to deal with their troubles.
