I wouldn't care about it if you did.So if I decided I no longer identified as fat, and now identified as thin, I would be thin?????
I have known people with weight problems who sorta did that. Part of their plan to reach a goal was to visualize themselves as thin, and perceive themselves as a thin person with too much weight. This as opposed to a fat person on a diet. This mental exercise apparently does often help people stay on track towards a goal of better health.
