What is BMI?▼

BMI (Body Mass Index) is a measure of body fat based on height and weight. It helps assess if you're at a healthy weight.

What is a healthy BMI?▼

A BMI between 18.5 and 24.9 is considered normal/healthy. Under 18.5 is underweight, 25–29.9 is overweight, and 30+ is obese.

Is BMI accurate?▼

BMI is a useful screening tool but doesn't measure body fat directly. Athletes may have high BMI due to muscle mass.
