Heavy and Bloated

I feel so heavy and bloated. I gained at least 10 lbs in just three months. I used to be very strict in my food intake, no sweets and soda. But for some reasons I always crave for chocolates recently and would have a few servings of root beer during snacks. I should rather take natural diuretic food like beets, oats and cabbage instead of sweets. There are also natural diuretic supplements that can help to lose weight and help eliminate water retention. My problem area is my tummy but my face and arms are now getting noticeably bloated. I wish I could find some supplements that would give an instant effect of weight loss.
