Alberto Ruben Serfaty, MD


We are father and son specialists in endocrinology and internal medicine. I was the first medical doctor in South America to work with ketogenic diets, bringing it to Brazil in the late 1970’s. Our clinic, Serfaty Clinicas, is the biggest clinic in Brazil for the treatment of obesity, diabetes, and preventive health, working with ketogenic diets and reversing all kinds of chronic diseases. With my son. Dr. Fabiano Serfaty, we treat not only patients with obesity, but also athletes, actresses, and models.
