Normal-Weight Obesity
Normal-weight obesity means a healthy BMI but excess body fat and low muscle — a pattern that still carries metabolic risk.
Plain English
Patient-Friendly Explanation
Normal-weight obesity means having a healthy BMI but excess body fat and low muscle — a pattern that still carries metabolic risk even though the scale looks fine.

Clinical Definition
Normal-weight obesity is defined as a normal BMI with elevated body fat percentage (typically ≥30% in women, ≥25% in men by BIA). It is associated with increased cardiometabolic risk, systemic inflammation and mortality comparable in some studies to class I obesity. Diagnosis requires body-composition measurement, as BMI cannot detect it.

Why It Matters
A normal BMI can hide high body fat — especially in Asian populations, where the same BMI carries more fat and more risk. This is exactly why the clinic's assessment includes an InBody scan rather than the scale alone.
