His father, Dr Robert Davis, is also a surgeon, making medicine a family tradition that would profoundly shape Garth’s career path. Growing up in a medically oriented household, Garth developed a keen interest in science and human health from a young age.

Davis served as the Medical Director of the Davis Clinic and as Medical Director for Bariatric Surgery at Memorial Hermann Memorial City Hospital. He also taught as an assistant professor of surgery at the University of Texas-Houston, contributing to the next generation of surgeons.
His television career began when he and his father starred in the hit TLC reality show Big Medicine, which documented the physical and emotional journeys of morbidly obese patients undergoing bariatric surgery. The show brought Dr Davis significant national visibility and helped destigmatize bariatric surgery for millions of Americans.
Dr Davis later moved to Asheville, North Carolina, where he served as Medical Director of the Weight Management Center at Mission Hospital. He subsequently returned to Houston, where he now practices at TLC Surgery, offering what he calls the “Davis Method” a personalized, concierge-style programme combining advanced bariatric surgery, medical weight loss options including GLP-1 medications, and plant-based nutrition guidance.

His 2015 book Proteinaholic: How Our Obsession with Meat Is Killing Us and What We Can Do About It, published by HarperOne, became a best-seller and ignited global conversations about protein consumption, meat eating, and chronic disease. In the book, Davis argues that excessive animal protein consumption is a root cause of obesity, diabetes, cancer, and heart disease, and advocates for a plant-based whole-food diet as the solution. He also appeared in the Netflix documentary What the Health, further amplifying his message to a global audience.
