Katharine Winter, BSc, MSc


I have been a low carb practitioner for over a decade following thought leaders like Dr. Longo, Dr. Jason Fung, Dr. Peter Attia, Rhonda Patrick, Ph.D., and more. I myself struggled with Hashimoto's thyroiditis for years before diagnosis and treatment. I have managed my own treatment and that of my clients with low carb, whole foods principles based on the ketogenic diet. I am dedicated to helping people discover The Nutrition Within. The answers to heal yourself, advocate for yourself and know yourself lies within you. The answers are not found in diet books, the internet or from your friends or family. I believe in nutrition that is simple and recognizes your individuality. I will teach you how to let your unique biochemistry and genes work for you. My goal is to empower you and teach you how to leverage nutrition to live your best life. I help my patients discover the healing powers of food, exercise, sleep, stress management and mental health balance.
