If you need to tip the balance scale in the direction of losing weight, keep in mind that it takes approximately 3,500 calories below your calorie needs to lose a pound of body fat. 1 To lose about 1 to 2 pounds per week, you'll need to reduce your caloric intake by 500â1000 calories per day.
When you gain weight, it usually creeps on slowly over several weeks or months -- not all at once in one day. Weight gain occurs when you consume more calories than you burn. A 3,500-calorie surplus -- 3,500 calories in addition to those you use every day -- will make you gain about 1 pound. Exactly how long it will take you to gain a pound depends on your basal metabolic rate, which is based on your genetics, age and gender, as well as your activity level.
