Loosing weight quickly can be dangerous. But I know a way to lose 1 pound a week. First multiply your weight by 15. Then just subtract 500 from your product and that is the number of calories you should eat a day. So if you're 200lbs you multiply that by 15(200*15=3000) and subtract 500 (3000-500=2500). That' the amount of calories you should eat a day. As you lose weight you'll have to adjust that number. Drinking water will help food cravings and start light exercise. Good luck!
