Just as the fellow above said, if you want to quickly lose weight, you should focus on getting rid of water from the body. For a week, drink a lot of water (4-5l per day) Attention! Consult it with your doctor because it could be dangerous if you have kidney problems or other health problems. And then (after week of drinking lot of water) cut off almost entirely water for two days, drink max 0.5 liter a day. The body will continue to defecate excess water and thus for a short period of time you will be able to lose a few pounds and reveal the muscles. It's a technique used by bodybuilders just before the competition to show their muscles as much as they can.
