About This Tool
Body Mass Index (BMI) is a simple, widely used screening tool that estimates your body fat based on your height and weight. While it doesn't measure body fat directly, it provides a reasonable snapshot for most adults of whether you're at a healthy weight.
- Underweight: Below 18.5 — may indicate malnutrition or underlying health conditions.
- Normal weight: 18.5 – 24.9 — associated with the lowest health risks.
- Overweight: 25.0 – 29.9 — increased risk of cardiovascular disease and diabetes.
- Obese: 30.0 and above — significantly elevated health risks.
