BMI for Asian Adults: Why the Cutoffs Are Lower

Who Was the Standard BMI Built For?

The familiar scale — 18.5 to 24 normal, above that overweight — comes mostly from European and North American data. Research shows that at the same BMI, Asian populations tend to carry more body fat, more visceral fat around the organs, and face higher risks of type 2 diabetes and heart disease at lower numbers. That's why the WHO publishes a separate set of cutoffs for Asia-Pacific.

Asia-Pacific BMI Categories (Adults)

Compare that with the global scale: the overweight line drops from 25 to 23, and obesity from 30 to 25. A person with a BMI of 24 reads as "normal" internationally but sits in the intervention zone under the Asia-Pacific criteria.

What to Check Beyond BMI

• Waist circumference: at or above 90 cm for men, 85 cm for women (Chinese criteria) signals abdominal obesity and predicts metabolic risk better than BMI alone
• Body fat percentage: above 25% for men, 30% for women is considered high; fit people often have a normal BMI with elevated body fat
• Waist-to-hip ratio: easy to measure and strongly tied to visceral fat
• Metabolic markers: healthy blood sugar, lipids, and blood pressure say more than the scale

Two Cautions Even with a "Normal" BMI

First, normal-but-high isn't risk-free. An Asian adult at BMI 23 with a sedentary desk job and a refined-carb-heavy diet still carries metabolic risk. Second, muscle inflates BMI. Strength athletes routinely read as overweight on paper; for them, body fat and waist size tell the truer story.

FAQ

Is a BMI of 24 overweight for Asian people?

Under Asia-Pacific criteria, overweight starts at 23. At 24, look at waist circumference and body fat alongside the number.

Should I use the Asian BMI scale?

Depends on your goal. Use the global scale to compare with international data; use the Asia-Pacific scale to judge health risk for Asian bodies.
