Michael MacDonald, MD, MBChB, BSc


I am a cardiologist and obesity physician based in Singapore. I have an interest in cardiometabolic conditions and the interaction between diabetes and cardiovascular disease. I have utilized low-carb/keto nutritional principles in numerous patients to improve their metabolic health. Diet Doctor is my go-to resource that I recommend for patients for general education on the principles.
