Ketogenic and Carnivore Diets: A Potential Breakthrough for Inflammatory Bowel Disease

The Silent Suffering of Inflammatory Bowel Disease

Inflammatory bowel diseases (IBD), including ulcerative colitis and Crohn's disease, can be devastating conditions that dramatically impact a person's quality of life. For many sufferers, the experience is one of silent pain and embarrassment, often hidden from even their closest peers.

The image of blood mixing with other bodily fluids is a stark reminder of the physical and emotional toll these diseases can take. For those diagnosed with IBD, life can change in an instant - from being active and successful to feeling fragile and withdrawn.

A Personal Journey

Dr. Norwitz, one of the researchers behind a new case series on ketogenic and carnivore diets for IBD, shares his personal experience with the disease. Diagnosed at a young age, he went from being a top athlete and student to feeling like a shell of his former self. This dramatic shift is a common story among IBD sufferers, but not all stories have a positive ending.

The Potential of Ketogenic and Carnivore Diets

Dr. Norwitz found remission through an experimental ketogenic diet, which he credits with saving his life - or at least his colon. However, the lack of rigorous dietary trials for extreme diets in treating IBD means that physicians are often unable or unwilling to recommend these approaches to patients.

The Research Gap

The absence of evidence for ketogenic and carnivore diets in treating IBD doesn't necessarily mean these approaches are ineffective. Rather, it highlights a significant gap in research. The question of whether these diets can help treat or even put IBD into remission remains largely unexplored in clinical settings.

Biological Plausibility

Despite the lack of clinical trials, there is biological evidence suggesting that ketogenic and carnivore diets could be beneficial for IBD:

1. Animal studies have shown therapeutic effects of ketones in IBD models
2. Lower colonic ketone levels correlate with worse IBD activity in humans
3. Ketones stimulate anti-inflammatory pathways
4. Ketones can promote stem cell renewal in the gastrointestinal tract
5. Elimination of certain dietary components can shift microbiome metabolism in potentially therapeutic ways

New Research: A Case Series of 10 IBD Patients

In a groundbreaking new study, Dr. Norwitz and his colleague Dr. Adrienne Scheck present a case series of 10 patients with histories of ulcerative colitis or Crohn's disease. These individuals, who had previously lived with severe suffering, report significant improvements in their quality of life after adopting ketogenic, primarily carnivore diets.

Key Findings

• All 10 patients are now in remission
• Remission periods range from 5 months to 5 years
• 8 out of 10 patients have been in remission for at least a year
• All patients are off medications for IBD

Previous Treatment Attempts

Many of these patients had tried numerous treatment options before finding success with their current diets, including:

• Corticosteroids
• Various biologics
• Immunomodulators
• Specific carbohydrate diet
• Low FODMAP diet
• Whole food plant-based diets

Measuring Quality of Life Improvements

The researchers used the validated IBD-Q32 questionnaire to quantify changes in quality of life. This tool assesses four domains:

1. Bowel symptoms
2. Systemic symptoms
3. Emotional impact
4. Social impact

The questionnaire has a maximum score of 224, indicating ideal quality of life with no symptoms.

Results

• Average pre-diet score: 95 (indicating poor quality of life)
• Average post-diet score: 216 (indicating clinical remission)
• Average improvement: 121 points

Diverse Patient Profiles

The case series included a diverse range of patients:

• 6 cases of ulcerative colitis
• 4 cases of Crohn's disease
• Male and female patients
• Ages ranging from 20s to 60s
• Varied body shapes and sizes
• Different dietary energy requirements

Current Dietary Practices

All patients in the study now follow a primarily animal-based ketogenic diet:

• 67-82% of calories from fat
• 21g or less of dietary carbohydrates daily
• Many patients following a strict carnivore diet

Patient Stories

The case series provides detailed accounts of how these diets have impacted individual patients. Here are two examples:

Patient 1: A 62-Year-Old Male with Crohn's Disease

• Diagnosed at age 30 while in law school
• Suffered for decades
• Now disease-free, confirmed by colonoscopy
• Reports that his keto-carnivore diet allows him to "forget" he had Crohn's
• Describes his decades with Crohn's as "another lifetime"

Patient 3: A 31-Year-Old Female with Family History of IBD

• Diagnosed at age 20 while pregnant
• Strong family history of IBD (brother, sister, and 10 first cousins affected)
• Experienced a four-fold drop in inflammatory markers within months of starting a carnivore diet
• Reports normal bowel movements within days and increased energy within 2 weeks
• No longer requires anti-TNF alpha biologics
• Doctor supportive of continuing the diet due to her improved condition

Limitations and Future Research

While the results of this case series are promising, the authors acknowledge several limitations:

1. Retrospective design
2. Selection bias
3. Lack of a control group
4. Small sample size

Dr. Norwitz emphasizes that this study is not meant to be definitive proof but rather a call to action for more rigorous research. He advocates for investing in controlled trials to further investigate the potential of ketogenic and carnivore diets in treating IBD.

Proposed Next Steps

The researchers suggest a randomized controlled trial comparing two extreme diets:

1. Whole food plant-based (possibly vegan) diet
2. Strict carnivore diet

Such a study, while potentially controversial, could provide valuable data on the efficacy of these dietary approaches for IBD treatment.

Addressing Potential Criticisms

Dr. Norwitz anticipates that this work may face criticism or be misinterpreted. He clarifies the following points:

• The researchers are not arguing that carnivore is the best human diet
• They are not claiming that fiber is inherently bad
• The study does not assert that ketogenic diets are superior for all conditions

Instead, the authors argue that ketogenic and carnivore diets may have therapeutic efficacy for IBD and potentially other autoimmune and inflammatory conditions. They stress the importance of further research to explore these possibilities.

The Importance of Open-Minded Scientific Inquiry

The researchers call for the scientific and medical communities to approach this topic with open minds. They emphasize the need to listen to patient experiences and invest in research that could potentially improve or even save lives.

By sharing this study and encouraging further investigation, the hope is to spark important discussions and drive progress in the treatment of inflammatory bowel diseases.

Conclusion

The case series presented by Dr. Norwitz and Dr. Scheck offers a compelling glimpse into the potential of ketogenic and carnivore diets for treating inflammatory bowel diseases. While not definitive proof, these patient stories highlight the urgent need for more comprehensive research in this area.

For those suffering from IBD, the possibility of finding relief through dietary interventions could be life-changing. As the medical community continues to explore new treatment options, it's crucial to remain open to unconventional approaches that may offer hope to patients who have exhausted traditional therapies.

Ultimately, the goal is to improve the lives of those living with IBD and other inflammatory conditions. By investing in rigorous research and listening to patient experiences, we may uncover new pathways to healing and remission for these challenging diseases.

As we move forward, it's essential to approach this topic with scientific rigor, compassion for patients, and a willingness to challenge existing paradigms. The potential benefits for IBD sufferers are too significant to ignore, and the medical community owes it to patients to explore all possible avenues for treatment and relief.
