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.
Definitions of Activity Level
Inactive: little or no exercise
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
Extremely Active: very hard daily exercise or sports; or physical job or 2X day training
Increasing your activity level will boost your metabolic rate. To lose weight, decrease calories consumed and/or increase calories used by about 500 calories per day.
