If your weight is part of the heredity factor then there is nothing to worry. Your body mechanisms know how to handle it. If your body weight cannot be attributed to heredity then there is a need to investigate for any underlying factors especially endocrine. Either ways worrying about it and centering your life around the physical body is the worst way to handle it. Turn your mind towards other much more important things than the body. It is enough if the body is given regular exercises so as to remain fit. I have met some very beautiful obese people who were loved by everyone because they exuded positivity and love and joy. There have been, on the other hand many who look very beautiful but are extremely difficult persons who turn life into a veritable hell. So while physical fitness is important, let it not preoccupy your mind space tol much. Do regular walking and exercises and avoid weight reduction medicines or surgeries that were designed for places and people for whom the body is everything.
