Ketogenic Diet Significantly Reduces Liver Fat and Prediabetes Risk Beyond Weight Loss

• A recent clinical trial published on August 27, 2026, found that a ketogenic diet dramatically cut liver fat by 67% in individuals with obesity, prediabetes, and fatty liver disease, outperforming Mediterranean and low-fat diets which achieved a 45% reduction. While all three diet groups lost approximately 10% of their body weight, the ketogenic diet's superior impact on liver fat suggests metabolic benefits extending beyond mere weight reduction. About half of the keto group also no longer qualified as having prediabetes after four to five months.

• A new framework for medical nutrition therapy has been proposed for patients with obesity-related heart failure with preserved ejection fraction who are on incretin-based therapies like semaglutide or tirzepatide. This framework, detailed in a narrative review in *Frontiers in Nutrition* on August 29, 2026, synthesizes data from major clinical programs to offer practical guidance on nutrition and muscle preservation.

• Research published on August 28, 2026, highlights how food environments in Viet Nam significantly shape adolescent diets, with most adolescents consuming food prepared outside the home, especially for breakfast and snacks. Interestingly, while these external food sources increase unhealthy fat and sodium intake, they also contribute key vitamins and minerals to adolescents' diets.
