Body Fat & Composition FAQ
Why Body Fat Percentage Matters More Than BMI
Body Mass Index (BMI) doesn't distinguish between muscle and fat. Two people with the same BMI can have vastly different health risks — one muscular and lean, another with excess body fat. Body fat percentage directly correlates with metabolic health, cardiovascular risk, and longevity. The US Navy method provides an accessible, no-equipment way to estimate body composition using simple circumference measurements. For Nigerians, where abdominal obesity is common even at normal BMI, this gives more accurate risk assessment.
Understanding Your Body Fat Category
Essential fat (minimum for health): men 2-5%, women 10-13%. Athletic range: men 6-13%, women 14-20%. Fitness range: men 14-17%, women 21-24%. Acceptable/healthy: men 18-24%, women 25-31%. Obese: men 25%+, women 32%+. Higher body fat increases inflammation, insulin resistance, and disease risk. Even moving from "obese" to "acceptable" range significantly improves health markers like blood pressure, blood sugar, and cholesterol.

Tips for Accurate Measurement
Measure first thing in the morning, before eating or drinking. Use a flexible tape, not metal. For neck: measure just below Adam's apple. For waist: at navel level, relaxed. For hips: at widest part of buttocks. Pull tape snug but not compressing skin. For consistency, have the same person measure each time and take two readings, averaging them. Avoid measuring after exercise or heavy meals.
