Calorie Calculator

Daily calorie needs vary by age, sex, height, weight, and activity level. On average, adult women need 1,600 to 2,400 calories per day and adult men need 2,000 to 3,000. Use the TDEE result from this calculator as your maintenance level, then adjust for your goals.

To lose approximately 1 pound (0.45 kg) per week, create a daily calorie deficit of about 500 calories. This adds up to 3,500 calories per week, roughly equivalent to one pound of fat. Most guidelines caution against going below 1,200 calories per day for women or 1,500 for men.
