Chizzy Nwankwo, MD, MPH, RD


I started following a low carb, ketogenic diet in 2015 while working with Dr. Eric Westman, the director of the Duke Lifestyle Medical Clinic during medical school. Since then, I have used it with patients with pre-diabetes, diabetes, auto-immune conditions and more with great success. My background in exercise physiology, nutrition and medicine have given me various skill sets to help patients overcome serious disease and disability with low carb nutrition and lifestyle modification. Diet Doctor is a great resource for me and my patients.
