The above link has information and many stories: One of the most prominent and dramatic stories is of Canadian Mikhaila Peterson, who had juvenile rheumatoid arthritis that was so severe she’d had three joint replacements (a hip and two ankles) before age 17. She also had extreme fatigue, anxiety and depression. In 2015 she began eliminating foods to see if a specific food was contributing to her autoimmune issues. She ended up eating just beef, salt and water — and all her symptoms disappeared.

Also some of the most scientific and nuanced writing on the carnivore diet is being done by Amber O’Hearn, who has two blogs, Empirica and The Ketogenic Diet for Health. A computational mathematician, O’Hearn has been a carnivore for almost a decade and says she will stay on it for life, because it is the only way of eating that she has found that controls her bi-polar disorder.
