Calorie Calculator helps you estimate personalized daily calorie targets for weight loss, weight gain, or weight maintenance based on your body data, activity level, BMI, TDEE, and weight goals. See how your weight may change over time and better understand your daily calorie needs.
Calorie Calculator is built on a science-based dynamic body weight model developed by Kevin D. Hall and colleagues. It makes calorie and weight loss estimates more realistic by considering that weight change is not perfectly linear — and that your metabolism, energy expenditure, and daily calorie needs can change as your body weight changes.
Many weight loss calculators still rely on the common 3,500-calorie rule, which suggests that cutting 3,500 calories equals one pound of fat loss. In reality, weight loss is more complex. Calorie Calculator uses a more dynamic approach to help you create clearer, more personalized calorie plans over time.
