Nonalcoholic fatty liver disease (NAFLD) prevalence in the US adult population is approximately 19.0%, with strong independent associations to obesity, diabetes, insulin resistance, and dyslipidemia.
NAFLD is a common condition affecting nearly 1 in 5 US adults, strongly linked to obesity, diabetes, and insulin resistance. It is often silent, meaning normal blood tests do not rule it out. Focus on metabolic health through weight management and blood sugar control to reduce liver fat.
The age-adjusted prevalence of NAFLD was 19% (95% CI: 17.5, 20.6), which corresponds to 28.8 (95% CI: 26.6, 31.2) million people in the United States... we found that there were strong independent associations between diabetes or insulin resistance, dyslipidemia, and obesity with NAFLD.
Why this rating
Large, nationally representative cross-sectional study (NHANES III) with objective imaging (ultrasonography), though limited by the 1988-1994 data collection period.

- 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
