Why a skinny waist on a heavy person might be riskier than BMI
Weight-adjusted waist index outperforms other obesity indices for cardiovascular disease prediction in cardiovascular-kidney-metabolic syndrome: insights from UK biobank

Surprising Findings
WWI outperformed waist circumference — the gold standard for abdominal fat — despite being simpler and cheaper to calculate.
For years, waist circumference was considered the best simple measure of visceral fat risk — but this study shows combining it with total weight makes it far more powerful.
Practical Takeaways
Calculate your WWI: Waist (cm) ÷ Weight (kg). If it’s above 0.55, talk to your doctor — especially if you have diabetes or high cholesterol.

People with a large waist relative to their body weight are more likely to have a heart attack or stroke later on, even when you account for other health problems like diabetes or high blood pressure.
WWI is especially good at spotting heart disease risk in younger people and those who already have diabetes, high cholesterol, or metabolic syndrome.
Waist circumference demonstrates superior predictive validity for metabolic disease and all-cause mortality compared to body mass index in adult human populations.
A measure combining waist size and blood fats (CMI) predicts heart disease risk—but only up to a certain point; beyond that, higher values don’t mean higher risk.
Measuring just waist size or blood fat levels alone isn’t as good at predicting heart disease risk in people with metabolic problems as using a combined measure like WWI.
