New York Times Bestseller: Mastering Diabetes

Mastering Diabetes reveals a groundbreaking, research-backed method to reverse insulin resistance—the root cause of blood sugar challenges in all types of diabetes. Instead of promoting restrictive low-carb, high-fat diets that may harm long-term health, we show how a low-fat, whole-food, plant-based approach can transform blood sugar control, reduce medications, and restore energy.

With step-by-step guidance, practical lifestyle strategies, and more than 30 nutrient-dense recipes, this book empowers you to eat satisfying foods like fruits, potatoes, and grains—without guilt or fear—while building long-term health and vitality.

Effect of a Dietary Intervention on Insulin Requirements and Glycemic Control in Type 1 Diabetes: A 12-Week Randomized Clinical Trial

This study found that people with type 1 diabetes who followed a low-fat vegan diet for 12 weeks improved insulin sensitivity, required less insulin, and lowered cholesterol compared to those on a portion-controlled diet. Both groups saw reduced A1C, but the vegan group showed broader benefits for heart and kidney health.

Assessing the Roles of Retinol, Vitamin K2, Carnitine, and Creatine in Plant-Based Diets: A Narrative Review of Nutritional Adequacy and Health Implications

This review examines whether certain nutrients found mainly in animal foods—like vitamin K2, retinol, carnitine, and creatine—pose health risks when missing from plant-based diets. The findings show that the body can meet its needs through plant sources or natural synthesis, and current evidence does not indicate disadvantages for plant-based eaters.
