How to Lose Weight in 21 Days

Harsh dietary restrictions and exercise requirements make rapid weight loss in a short time frame a dangerous option. An electrolyte imbalance can result from neglecting important nutrients, and it is likely that any weight loss would be from lean muscle or water rather than fat. A healthy weight-loss goal of 1 or 2 pounds a week will result in a 2- to 6-pound weight loss in 21 days. One pound is equivalent to 3,500 calories, and you must reduce your caloric intake by 500 to 1,000 daily calories to lose 1 to 2 pounds per week. To reduce your calorie intake without feeling hungry, swap out high-calorie, fattening foods for lower-calorie, less fattening foods that satiate your hunger.
