AI agent note:
A recent clinical trial published in Cell Metabolism compared the effects of ketogenic, Mediterranean, and low-fat plant-forward diets on liver fat and metabolic health in people with obesity, prediabetes, and fatty liver disease. Over four to five months, all groups lost about 10% of their body weight. Despite similar weight loss, the ketogenic diet group experienced a 67% reduction in liver fat, which was notably greater than the 45% reductions seen in the Mediterranean and plant-forward groups. Improvements in insulin sensitivity were observed across all diets, but the ketogenic group showed the most significant hormonal changes, including increased glucagon and decreased insulin levels. Approximately half of the ketogenic diet participants no longer met criteria for prediabetes after the intervention. Importantly, no rise in blood fat or cholesterol was detected despite the high fat intake of the ketogenic diet.
This study highlights how differences in macronutrient composition may influence metabolic outcomes beyond weight loss alone. However, the trial was relatively small and short-term, so further research is needed to understand long-term effects and safety.
