There is nothing wrong with mas*urbat*on, and I have never heard of it being the cause of losing weight. But if you are finding that you are doing it to much for your body and its starting to hurt your muscles then try and pick up a different hobby, start bike riding or reading books or doing something to keep your mind off mas*urbat*ng. keep yourself busy.
