BMI or Body Mass Index is a measurement of a person's weight with respect to their height. It is more of an indicator than a direct measurement of a person's total body fat.

How is BMR different from TDEE?

BMR (Basal Metabolic Rate) is the calories your body burns at complete rest. TDEE (Total Daily Energy Expenditure) is your BMR plus the calories burned through physical activity.

Medical Definitions

Body Mass Index (BMI)

A screening tool used to identify individuals who are underweight, overweight, or obese. It is not a diagnostic of body fat percentage but a useful general indicator.

Basal Metabolic Rate (BMR)

The minimum amount of energy required to keep your body functioning at rest (breathing, heart beating, cell production).

Frequently Asked Questions

How accurate is this BMR calculation? ↓

We use the Mifflin-St Jeor Equation, which is currently considered the most accurate predictor for healthy adults without specialized medical equipment.

Does BMI apply to athletes? ↓

Athletes often have higher muscle mass, which is denser than fat. This may result in a 'High BMI' even if their body fat percentage is very low.
