Keto Diet Outperforms Other Diets in U.S. Trial

Multiple recent clinical reviews and reports converge on a ketogenic diet as offering metabolic advantages for people with obesity, prediabetes, and fatty liver beyond mere weight loss. The trials show that after four to five months on a keto plan, roughly half of participants no longer meet prediabetes criteria, and liver fat and insulin-related markers improve more than with Mediterranean or low-fat diets. While all three diets improved overall metabolic health, the ketogenic approach delivered extra benefits for liver fat reduction and blood-sugar control. Study designs varied in size—from about 42 to 55 participants—and all emphasized strict adherence to diet type to isolate its effects, with researchers noting that carbohydrate reduction may have therapeutic effects for those with prediabetes and fatty liver. These findings suggest diet composition matters for metabolic health, not just weight loss, though researchers caution that long-term effects require further study. Overall, keto shows promise as a more effective option for certain metabolic risk factors, relative to Mediterranean and low-fat plant-forward plans, in the populations studied.
