How to lose 10 lbs: The only way to lose weight is to use more calories than one is eating or drinking in. Losing 10 pounds should take 10 weeks, and can happen if a person eats or drinks 500 calories less than he uses each day. For example, eat 1300 calories a day but use up 1800 each day. That means one can eat many calories, as long as he uses 500 more than he eats every day.
