How to Use the Obesity Complication Risk Calculator
Obesity increases the risk of type 2 diabetes, hypertension, cardiovascular disease, fatty liver, and sleep apnea. Waist circumference is used alongside BMI to assess abdominal fat, which carries higher metabolic risk than subcutaneous fat.
High-risk abdominal obesity thresholds (NCEP/AHA): men ≥ 40 in (102 cm), women ≥ 35 in (88 cm). Even a 5–10% weight loss significantly reduces all complication risks.
Frequently Asked Questions
Yes. "Metabolically obese normal weight" (MONW) describes people with normal BMI but high body fat percentage and excessive waist circumference. These individuals still face elevated metabolic syndrome risk.
Combining caloric restriction with aerobic exercise (150+ min/week) is the gold standard. High-protein, low-carbohydrate diets and adequate sleep are key adjuncts. For BMI 35+ with complications, bariatric surgery may be considered.
A 5–10% reduction from current weight is the first meaningful medical target. Achieving a BMI below 25 reduces long-term complication risk most substantially. Work with your doctor on a realistic, sustainable timeline.
