About Me

After 20 years of clinical and research experience using low carbohydrate, ketogenic diets, I am continually amazed at how health can be improved by just changing the food that someone eats. I use an approach that is simple and effective, and evidence-based. Medical conditions, like type 2 diabetes, obesity, hypertension, GERD, fatty liver, and PCOS, can all be improved or even reversed through food. I am specialized in internal Medicine and obesity medicine, and I am the author of the books End Your Carb Confusion, The New Atkins for a New You, Keto Clarity, and Cholesterol Clarity.
