I think its easier to pick at body imperfections. I do it all the time, especially since I'm bigger than most of my friends. (They are all 110-120 twigs)

It has helped me to look at myself and think of my body positively. I don't feel terrible being at my weight anymore and know that as I gain more courage I will be able to stick to fitness/diet plans.

Try to eat some healthy but fatty foods. Things like nuts (if you aren't allergic to it) can help. Also eating more meat than you actually need. (Anything deep fried but that isn't healthy...)
