Overweight: BMI 25–29.9
Obesity Class I: BMI 30–34.9
Obesity Class II: BMI 35–39.9
Obesity Class III: BMI 40 or higher

Body Fat Percentage

Body fat percentages for men:

Waist Circumference

Abdominal fat poses higher health risks than fat distributed elsewhere.

Men: Increased risk at >94 cm (37 in), substantially increased risk at >102 cm (40 in)
Women: Increased risk at >80 cm (31.5 in), substantially increased risk at >88 cm (34.6 in)

Waist-to-Hip Ratio

WHR helps identify apple-shaped vs. pear-shaped fat distribution:

For men: >0.9 indicates increased health risk
For women: >0.85 indicates increased health risk

Waist-to-Height Ratio

Your waist circumference should be less than half your height. A ratio greater than 0.5 indicates increased health risk.
