What Is BMI?
Body Mass Index (BMI) is a simple calculation using your height and weight that helps classify adults into weight categories. It's used by health professionals as a screening tool to identify potential weight problems in adults.
BMI Categories
- Under 18.5 — Underweight
- 18.5 – 24.9 — Normal or Healthy Weight
- 25.0 – 29.9 — Overweight
- 30.0 and above — Obese
Limitations of BMI
BMI is a useful screening tool but has limitations. It doesn't directly measure body fat, and it may overestimate body fat in athletes and muscular individuals, or underestimate body fat in older adults who have lost muscle. BMI is also not suitable for children, pregnant women, or people with certain medical conditions.
Maintaining a Healthy Weight
If your BMI falls outside the healthy range, small changes can make a big difference. Focus on balanced nutrition, regular physical activity, adequate sleep, and gradual, sustainable lifestyle changes rather than extreme diets.
