Summary: The carnivore diet has become increasingly popular for everything from weight loss to general health, and many with IBD have reported miraculous results, including one written up and published as a case report. However, a strict carnivore diet (especially with our modern tastes) is not a tried and true strategy for humans: populations that have traditionally subsisted on mostly animal foods do still eat some plant foods, and usually have very specific dietary patterns that most modern carnivores don’t come close to replicating. A carnivore diet could absolutely still be worth trying for IBD, especially if nothing else has worked, but care should be taken to monitor for any issues related to hydrogen sulfide overproduction or metabolism and general health. Certain strategies, such as keeping the fat-to-protein ratio supportive of ketosis and including specific microbiome-supporting foods like cranberries, could help minimize risk and maximize chances of success.

The carnivore diet is like the sexier, more exciting cousin of the ketogenic diet (which I covered in the linked post). Rather than hewing to a certain macronutrient ratio, a carnivore diet simply eliminates any food that comes from a plant, only including foods that come from animals. This makes it far simpler to follow, and also more fun (if you’re the type of person who enjoys all the connotations of being a “carnivore” and feeling superior for eschewing lame plant foods).
Many people with IBD have reported miraculous results from adopting a carnivore diet, but many also claim that a stint of carnivore dieting ruined their health. So what are the considerations surrounding a carnivore diet in the context of IBD?[Read more…] about Carnivore Diet for Ulcerative Colitis and Crohn’s Disease
