Try to remember that he may not experience the same negative reaction to being fat that you have had. You grew up being fat when you were younger and less able to stick up for yourself, but he is wanting to become fat as an adult and will hopefully have the confidence to ignore any negative reactions he may receive.
He wants to deliberately become fat because he can see the beauty and sexuality in it and this may help you to overcome your own negative feelings. Try to enjoy it together with him, make feeding and name calling fun and see how horny he gets. Let his positivity about it rub off on you and you may start to feel more positive about your own body and see that all those name callers in the past were just ignorant idiots.
