Frequently Asked Questions

What is a healthy BMI?

A BMI of 18.5–24.9 is considered normal weight. Below 18.5 is underweight; 25–29.9 is overweight; 30+ is obese.

Is BMI an accurate measure of health?

BMI is a useful screening tool but does not distinguish between muscle and fat. Athletes may have a high BMI but low body fat.

How is BMI calculated?

BMI = weight (kg) ÷ height² (m²). For example, 70kg ÷ (1.70m × 1.70m) = 24.2.

What should I do if my BMI is in the overweight range?

Consult a healthcare provider. Lifestyle changes like a calorie-controlled diet and regular exercise can help. The Oatmeal app can help you track.
