Sarah Ballantyne

Dr. Sarah Ballantyne, PhD, New York Times bestselling author and renowned health expert, creates educational resources to help people improve their day-to-day diet and lifestyle choices, empowered and informed by the most current evidence-based scientific research. Dr. Sarah began her career as a science communicator and health educator when she launched her original website in 2011. On this platform, Dr. Sarah combined her background in medical research with her experience using diet and lifestyle to lose 120 pounds while mitigating a dozen diagnosed health conditions to create a wealth of educational resources and amass an audience of millions. Since then, Dr. Sarah has continued to follow the science—diving deep into immune health, metabolic health, gut microbiome health, nutritional sciences, and the compelling evidence for health at any size—while also observing the harm of healthism, diet culture, dogmatic misinformation, and predatory marketing. With Nutrivore, Dr. Sarah has created a positive and inclusive approach to dietary guidance, based in science and devoid of dogma, using nutrient density and sufficiency as its basic principles: nourishment, not judgment.
