Dr. Eric Berg
Chiropractor and Nutrition Content Creator
Eric Berg holds a Doctor of Chiropractic degree and has built one of the largest health and nutrition YouTube channels, with tens of millions of subscribers. His content focuses primarily on the ketogenic diet, intermittent fasting, and nutritional health, and he presents himself consistently as "Dr. Berg" in his branding, thumbnails, and on-screen text. He holds a DC (Doctor of Chiropractic) credential, not an MD (medical doctor) credential, though this distinction is not prominently communicated in his content.
Critics including the McGill University Office for Science and Society have noted that audiences consuming Berg's content may reasonably assume they are receiving advice from a physician, and that this misimpression is not dispelled by his presentations. He regularly makes claims about nutrition, disease management, and treatments for conditions including cancer, diabetes, and autoimmune disorders — areas that fall outside the scope of chiropractic practice. Registered dietitians and medical professionals have challenged specific claims Berg makes about the ketogenic diet's ability to treat or cure various conditions, arguing that the evidence he cites does not support the sweeping conclusions he draws.
Berg operates a commercial supplement store and his content frequently points viewers toward purchasing his branded products as solutions to health concerns raised in his videos. He published videos during the COVID-19 pandemic questioning vaccine safety and promoting alternative treatments, content that health authorities and fact-checkers characterized as potentially harmful misinformation. He also promotes dietary approaches for serious medical conditions in ways that nutritional scientists have said exceed what the research supports.
Berg's supporters argue that his content has helped many people improve their health through dietary changes and that he provides accessible, practical information that conventional medical providers often don't discuss. Independent scientific reviewers generally find his content ranges from moderately useful on dietary topics to significantly misleading on medical claims.
