About the BMI Calculator
This calculator computes your Body Mass Index from height and weight, places it into the standard underweight/normal/overweight/obese categories, and estimates your Basal Metabolic Rate using the Mifflin-St Jeor equation. Multiplying BMR by your activity level gives your Total Daily Energy Expenditure — roughly how many calories you'd need to maintain your current weight. Use TDEE as a starting point for setting a calorie target, adjusting up for weight gain or down for weight loss.
