How to stop body checking

I doubt I would have stopped body checking as long as I fear weight gained and had the same goals. So working on accepting how ever the body needs to be to be healthy is one way to go about it. Another is to set new goals. Instead of the goal "be thin" have a goal of for example getting optimal health, taking as good care of the needs of the body as possible, getting strong (you feel stronger by eating enough. No need to do strength training for that.), get over fears, improve communication skills to get needs met more efficiently ( like non violent communication by Marshall Rosenberg), be more social, be more present with the inner child / the emotions and our needs on all levels of our being, have a daily meditation and prayer practise (instead of body checking you can check in on what you feel and need and use prayer beads if you need to touch something to calm yourself). 

Make a list of what is positive about weight gain / optimal weight for your body (type) for example. I can give you a list: No more feelings of stress and nervousness caused by hunger, no more extreme hunger, no more hiding my natural look and being ashamed of being fake, vain and manipulative, no more giving in to fear (of weight gain), being a body positive role model that indirectly tells others it is safe to look natural, be able to feel love instead of fear, be able to help others overcome their ED, no more dishonesty around food and exercise, finally relaxing and sleep better, less fragile.
