A new study published in Cell Metabolism reveals the surprising benefits of the keto diet on liver health.
Researchers investigated 42 adults with obesity, prediabetes, and excess liver fat. In a randomized clinical trial, participants were assigned to one of three diets:
- Low-carb ketogenic diet: Approximately 4% carbohydrates and 73% fat.
- Mediterranean diet: Around 50% carbohydrates and 35% fat.
- Low-fat, mostly plant-based diet: Approximately 70% carbohydrates and 15% fat.
Across all three groups, muscle insulin sensitivity improved by about 50%, allowing muscles to more efficiently take up blood sugar.
Notably, the keto diet resulted in a significant reduction in liver fat, decreasing by roughly 67%, compared to approximately 45% with the other diets. Furthermore, liver insulin sensitivity improved two to three times as much in the keto group compared to the other diet groups.
