Losing weight on an empty stomach means cutting off fat, but you should stick to losing weight for a long time. And at the same time of hunger strike, do some aerobics appropriately, that is, simple movements often recommended by websites and magazines. Doing it repeatedly can consolidate the weight loss effect, tighten the skin, and make the skin not loose because of weight loss.

If you just lose weight by not drinking water, you cut off the water and it is easy to rebound.
