Weight Loss & Diet Plans

Metabolism Calculator

This calculator estimates your basal metabolic rate and calorie needs based on your gender, height, weight, age, and activity level. However, frame size, medications, health conditions, body fat percentage, and other factors can change your calorie needs significantly. If you have questions about your overall calorie requirements, check with your health care provider.

Lightly Active: light exercise or sports 1-3 days/week

Moderately Active: moderate exercise or sports 3-5 days/week

Very Active: hard exercise or sports 6-7 days/week
