After his educational and research years in Nutrition, he pursued a clinical Fellowship in Nutrition at Memorial Sloan-Kettering Cancer Center, one of the most respected hospitals in the world.

Since learning the benefits of the low-carbohydrate/ketogenic (“keto”) diet, Dr. Weiss studied with Karen Lee Raymond, Ph.D. in Brisbane, Australia, nutritionist researcher and clinician, and author of the book “Processed Food Addict: Is this Me?” (KLWR Publications, 2019).
