Advanced BMI & Health Calculator

BMI is a general screening tool and may not account for muscle mass, bone density, age, and other factors. Athletes may have higher BMI due to muscle mass. Use BMI as one indicator alongside other health metrics.

We use the Mifflin-St Jeor equation, which is considered the most accurate formula for calculating BMR. It takes into account weight, height, age, and gender.

To lose weight, aim for the "Lose Weight" calorie target (typically 500 calories below TDEE). To maintain, eat at your TDEE. To gain weight, aim for the "Gain Weight" target (typically 500 calories above TDEE). Always consult a healthcare provider for personalized advice.
