Dr Ken Berry

Ken Berry is a board-certified family physician practising in rural Tennessee. He earned his MD from the University of Tennessee Health Science Center in 2000, holds Fellow status with the American Academy of Family Physicians (FAAFP), and has seen over twenty thousand patients in primary care. He runs the largest carnivore-and-keto YouTube channel by a practising MD — over 3.5 million subscribers — building a plain-spoken audience around what he calls the "Proper Human Diet".

His 2017 self-published book "Lies My Doctor Told Me" was reissued in a 2019 second edition by Victory Belt Publishing. It sits in the carnivore-adjacent canon — its target is conventional dietary advice rather than carnivore specifically, but most readers find their way to meat-first eating through it. In 2023 he co-authored "Common Sense Labs" with Kim Howerton, a practical guide to interpreting routine blood work.
