How to Use the Visceral Fat Risk Calculator
Visceral fat builds up around your internal organs, and unlike subcutaneous fat, it's not always visible — yet it's closely linked to metabolic syndrome, including high blood pressure, diabetes, and abnormal cholesterol. This calculator uses your waist circumference and height to compute the waist-to-height ratio (WHtR), then combines it with sex-specific waist cutoffs to show a normal, caution, or high-risk level.
For an accurate measurement, measure your waist at navel level after exhaling normally. Under U.S. guidelines, a waist of 40 inches or more in men, or 35 inches or more in women, is classified as abdominal obesity, and a waist-to-height ratio above 0.5 signals a waist that's disproportionately large for your height. At the same body weight, more visceral fat means a much higher risk of metabolic disease, so tracking waist circumference can be a more practical health indicator than the scale alone.
