How can you lose weight fast without exercise?

The best way to lose weight quickly without the need to exercise is to restrict your daily calorie intake, states WebMD. Although calorie restriction is an effective weight loss tool, excessive caloric restriction can do more harm than good.

If you wish to lose weight without exercising, the best method is a healthy, well-rounded diet that is within a healthy daily calorie intake. WebMD recommends a weight loss goal of 1 to 2 pounds per week as the healthiest course of action. In order to do this, simply eat 500 less calories per day than you burn naturally. It takes a loss of about 3,500 calories to lose 1 pound.
