For me at least ... and I'm learning that nothing I feel is new or unique when it comes to my body ... pride has a huge influence. "I caused the probelm, but I have overcome!"
Although I would like to take credit for overcoming ... it is a comfort to know that perhaps it wasn't all my fault. If I have to battle to stay slim, at least I know I'm not just battling a willpowerless me.
Is there a difference in how this factor is viewed by those how have lost weight as opposed to those who are actively losing?
Eat good food. Move yourself. Lift something.
You'll be surprised how much you don't miss grain.
