This randomized clinical trial examined the impact of different macronutrient compositions in diets on cardiometabolic responses to moderate weight loss in individuals with metabolically unhealthy obesity. The study found that a very-low-carbohydrate diet led to a two-to-three-fold greater increase in hepatic insulin sensitivity compared to other diets, with a p-value of less than 0.001.
Key findings
- Weight loss increased muscle insulin sensitivity by approximately 50% across all diet groups.
- The very-low-carbohydrate diet resulted in a two-to-three-fold greater increase in hepatic insulin sensitivity compared to other diets.
- Intrahepatic triglyceride content and hepatic de novo lipogenesis decreased most in the very-low-carbohydrate group.
Why it matters
Understanding the differential effects of diet macronutrient composition on metabolic health can guide clinicians in recommending dietary interventions for patients with obesity-related metabolic disorders.
