Which Diet Is Best to Lower Liver Fat and Improve Insulin Sensitivity?
6 hours ago
- A randomized trial compared keto, Mediterranean, and low-fat plant-forward diets in 42 participants with metabolically unhealthy obesity after 10% weight loss.
- All diets equally improved muscle insulin sensitivity by about 50%, but the keto diet outperformed in reducing liver fat (67% vs 45%) and improving hepatic insulin sensitivity (nearly tripled vs 50-80%).
- The keto diet resulted in greater reductions in fasting glucose, insulin, HOMA-IR, and triglycerides, and reversed prediabetes in 50% of participants (vs 29% Mediterranean, 7% low-fat).
- Superior results on keto are attributed to lower carbohydrate intake reducing insulin levels and de novo lipogenesis, plus higher protein content and ketosis shifting fatty acids to ketone production.
- Weight loss is the top priority; higher protein and low glycemic load diets help break the vicious cycle of hyperinsulinemia and liver fat accumulation.
- Sustainability matters: a short-term keto diet can initiate improvement, then transition to a maintainable high-satiety diet with adequate protein and minimal added sugars and alcohol.
- Resistance training at least twice weekly is recommended to preserve muscle mass during weight loss, improving long-term metabolic health and functional aging.
- The study did not find significant differences in LDL cholesterol or blood pressure among diets, but trends favored the Mediterranean diet; more research is needed for cardiometabolic risk factors.
