In individuals with a normal BMI (18.5–24.9 kg/m2), high body fat percentage (Normal Weight Obesity) is associated with a significantly higher prevalence of cardiometabolic dysregulation and, specifically in women, an independent increase in cardiovascular mortality risk.
If you have a normal BMI, do not assume you are metabolically healthy. High body fat percentage (Normal Weight Obesity) is a significant risk factor for heart disease and death, especially in women. You should assess your body composition (e.g., via DEXA or bioimpedance) rather than relying solely on your weight. Focus on building lean muscle and reducing body fat through resistance training and nutrition, even if your weight stays the same.
Normal weight obesity, defined as the combination of normal BMI and high BF content, is associated with a high prevalence of cardiometabolic dysregulation, metabolic syndrome, and CV risk factors. In women, NWO is independently associated with increased risk for CV mortality.
Why this rating
Large sample size (n=6171), long follow-up (median 8.8 years), and rigorous adjustment for confounders, though it is an observational cohort study.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
