Summary
A randomized trial of 42 adults with obesity, prediabetes and fatty liver disease found keto delivered the biggest metabolic gains after four to five months, even though all diet groups lost about 10% of body weight.
Liver fat fell 67% on keto versus 45% on both Mediterranean and low-fat plant-forward diets, suggesting carbohydrate restriction added benefits beyond weight loss alone.
About 50% of keto participants no longer met criteria for prediabetes, compared with 29% on the Mediterranean diet and 7% on the plant-forward diet.
Researchers said keto participants also showed the largest rise in glucagon and drop in insulin over 24 hours, while blood fat and cholesterol did not increase despite the diet's 73% fat content.
The Cell Metabolism study adds to evidence that diet composition can shape metabolic outcomes even as GLP-1 drugs increasingly drive obesity treatment.
