The Keto Study That Wasn't About Keto | Dr Nicola Guess

A recent Washington University study comparing ketogenic, Mediterranean, and plant-rich diets reveals that significant reductions in liver fat stem primarily from increased protein and reduced carbohydrate intake rather than ketosis. Dietitian Dr. Nicola Guess notes that while the ketogenic diet yielded positive results, the observed benefits are likely driven by macronutrient shifts that enhance metabolic function. Sustainable metabolic improvement relies on combining high-protein, low-carb patterns with heart-healthy unsaturated fats, rather than adhering to strict ketogenic protocols. Weight loss remains the most critical factor for normalizing cardiometabolic markers like HbA1c and glucose tolerance. Furthermore, evidence suggests that fiber intake and the inclusion of nuts and seeds provide additional cardiovascular protection. This approach offers a practical, evidence-based framework for managing fatty liver and insulin resistance without relying on restrictive dietary labels or avoiding specific plant-based oils.
