How to learn to respect your body?

You need to remember about genetics and heredity. For example, if you are naturally 165 cm tall with broad shoulders and legs that are very average in relation to the torso, then you will never get a thin and long figure of a classic catwalk model, even if you refuse to eat at all. Love yourself at the weight that you are at the moment - then it will be easier for you to work on the body from a point of love, and not shame or self-hatred.
