What is a healthy BMI?
A BMI between 18.5 and 24.9 is considered healthy for most adults. Below 18.5 is underweight, 25–29.9 is overweight, and 30 or above is classified as obese.
Is BMI an accurate measure of health?
BMI is a useful screening tool but has limitations. It does not distinguish between muscle and fat mass, so athletes may be classified as overweight even when very lean. Use BMI alongside other measures like waist circumference and body fat percentage.
What is the difference between BMI and body fat percentage?
BMI is a ratio of weight to height and is quick to calculate but imprecise. Body fat percentage directly measures the proportion of fat in your body, giving a more accurate picture of body composition.
Does BMI apply the same way to athletes?
Not always. Athletes with high muscle mass often have an elevated BMI despite low body fat. For athletes, body fat percentage and DEXA scans are better indicators of health and performance.
