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.
