Understanding Your Calorie Needs

Your daily calorie needs are determined by your basal metabolic rate (BMR) and your level of physical activity. The BMR is calculated using your age, gender, weight, and height.

Multiplying your BMR by an activity factor gives you your maintenance calories—the number of calories you need to maintain your current weight. Reducing this number by around 500 calories per day can help you lose weight gradually.
