You better start appreciating how you look now, because taking diuretics will lead to a superficial temporary weight loss, but then you will regain and possibly gain more. If you dislike how you look now, you won't like your body when it is 5-10 lbs heavier than now.

Better be reasonable, eat and do a combo or cardio and resistance to make the body look and feel better at the current weight. It is a much safer approach, in terms of reducing the risk of gaining more and yet more.
