Carnivore 4 Inflammatory Bowel Disease
The carnivore diet shows promising potential for treating inflammatory bowel disease (IBD), including both ulcerative colitis (UC) and Crohn's disease. Here are the key findings and considerations:
Case Series Results
10 cases of IBD (6 UC, 4 Crohn's) responded positively to ketogenic or carnivore diets[1][2].
Clinical improvements were universal, with Inflammatory Bowel Disease Questionnaire (IBDQ) scores improving by 72 to 165 points[1][2].
Patients' diets consisted primarily of meat, eggs, and animal fats[1][2].
Several patients were able to discontinue medications while maintaining remission[1][4].
Patient Experiences
Patients reported their diets as pleasurable, sustainable, and significantly enhancing their quality of life[1][2].
Symptom improvements were often rapid, with some patients noting changes within days of starting the diet[4].
Many patients experienced resolution of symptoms like bloody stools and abdominal pain[4].
Potential Mechanisms
The therapeutic potential of the carnivore diet for IBD may be related to:
Its nature as an elimination diet, removing potential trigger foods[2].
Induction of ketosis, which may have anti-inflammatory effects[2].
Reduction of fermentable plant matter, potentially altering gut microbiota metabolism[4].
Considerations
The study was small and lacked a control group, indicating the need for more rigorous research[3].
Long-term effects and nutritional adequacy of the carnivore diet for IBD patients are not well-established.
The diet is highly restrictive and should only be attempted under medical supervision.
Conclusion
While the carnivore diet shows promise for IBD treatment based on these case reports, larger controlled studies are needed to confirm its efficacy and safety. The diet appears to be well-tolerated and potentially effective for some patients, but individual responses may vary. Patients interested in trying this approach should consult with their healthcare providers to ensure proper monitoring and support.

Keto For IDB? Not as good as Carnivore?
The impact of a ketogenic diet (KD) on inflammatory bowel disease (IBD) is complex and somewhat controversial based on the current research. Here's an overview of the key points:
Potential Benefits
Some studies suggest ketogenic diets may have beneficial effects for IBD:
A case report found that a paleolithic ketogenic diet led to remission of symptoms and normalization of intestinal inflammation in a severe case of Crohn's disease[4].
One study observed that a ketogenic diet protected intestinal barrier function and reduced inflammatory responses in a mouse model of colitis[3].
The ketogenic diet may alter the gut microbiome in potentially beneficial ways, increasing some beneficial bacteria like Akkermansia[3].
A case series reported clinical improvements in 10 IBD patients following ketogenic or carnivore diets, with increases in quality of life scores[2].
Potential Risks and Concerns
However, other research has found ketogenic diets may worsen IBD:
A study in mice found that a ketogenic diet substantially aggravated colitis, increased intestinal permeability, and altered the gut microbiome in potentially harmful ways[1].
The high fat content of ketogenic diets may increase inflammation in some cases[5].
Ketogenic diets are very restrictive and may make it difficult to obtain adequate nutrition and fiber[5].
Mechanisms and Considerations
The effects of ketogenic diets on IBD likely involve complex interactions with:
The gut microbiome and metabolites
Intestinal barrier function
Inflammatory pathways
Ketone bodies
Individual responses may vary significantly. Some patients report symptom improvements, while others may experience worsening.

Comparison of Keto vs Carnivore Diets for IBD
Based on the available research, both carnivore and ketogenic diets show some potential benefits for inflammatory bowel disease (IBD), but there are important differences and considerations to note:
Carnivore Diet
The carnivore diet, which consists almost exclusively of animal products, appears to have some promising results for IBD treatment according to recent case studies:
A case series of 10 IBD patients reported universal clinical improvements when following carnivore or ketogenic diets, with increases in quality of life scores[1][2][3].
Patients on carnivore diets experienced resolution of symptoms like bloody stools and abdominal pain, with some able to discontinue medications[3].
The diet was reported as pleasurable and sustainable by patients[1][2].
Ketogenic Diet
The ketogenic diet, which is very low in carbohydrates and high in fats, shows mixed results:
Some studies suggest it may have anti-inflammatory effects and protect intestinal barrier function[4].
However, a mouse study found that a ketogenic diet substantially worsened colitis, increased intestinal permeability, and altered the gut microbiome in potentially harmful ways[7].
Comparison
The carnivore diet appears to be more restrictive than standard ketogenic diets, eliminating virtually all plant foods.
Both diets can induce ketosis, which may have anti-inflammatory effects.
The carnivore diet may act as a more extreme elimination diet, potentially removing more trigger foods for IBD patients.
Ketogenic diets typically include some plant-based foods and may offer more dietary variety than strict carnivore diets.
In conclusion, while both carnivore and ketogenic diets show some promise for IBD treatment, the carnivore diet appears to have more positive case reports specifically for IBD. However, the long-term implications and optimal implementation of either diet for IBD management require further research.
