Do fat people only think of food?  

i dont think so .. i think ,they think about how to be slim ;when they become fat. i have gained some weight n now i always think about to reduce

For one fat people are just like everyone else so you shold be respectful. Not alll overweight people are the same just like all skinny people are not the same. Sometimes people become overweight because they use food as comfort. Perhaps the person asking thouse questions may not have much else to look forward to. I would try to engage then in a fun activity so they are not just waiting around for the next time to eat. Maybe they are bored.

nope not at all. there is nothing like that. fat people are some time more creative, hard worker than thin or slim people. i have seen a lot of people who are very thin but talks about food only and fat people who hardly eat much. so he might have some psychological problems too.
