Case Report Carnivore–ketogenic Diet For The Treatment Of Inflammatory Bowel Disease A Case Series Of 10 Patients

This case study examined whether very low-carbohydrate diets, specifically ketogenic and carnivore diets, could help treat inflammatory bowel disease (IBD). IBD includes conditions like ulcerative colitis and Crohn's disease, which cause chronic inflammation in the digestive tract and can severely impact quality of life. The researchers recruited 10 patients through social media who had doctor-confirmed IBD diagnoses and reported improvement on these restrictive diets.

The study included 6 people with ulcerative colitis and 4 with Crohn's disease. All participants followed diets consisting mainly of meat, eggs, and animal fats, with very few or no carbohydrates. Remarkably, every single patient experienced significant clinical improvement, with symptom relief scores ranging from 72 to 165 points on a standardized IBD assessment tool. Many were able to reduce or eliminate their medications while maintaining their improvement. Patients reported that their diets were enjoyable, sustainable, and dramatically improved their quality of life.

The researchers suggest these improvements may occur because ketones (produced when the body burns fat instead of carbohydrates) have anti-inflammatory effects in the intestines. Additionally, eliminating most plant foods may reduce irritation to the inflamed digestive tract. However, this was a very small study without a control group, so larger, more rigorous trials are needed.

While these results are promising, such restrictive diets require careful medical supervision and may not be appropriate for everyone. Patients with IBD interested in dietary interventions should work closely with their healthcare team to develop a safe, personalized approach that considers their specific condition, nutritional needs, and overall health goals.
