Ulcerative Colitis

Ulcerative colitis, an inflammatory bowel disease characterized by ulcers and chronic inflammation in the large intestine, typically consigns patients to lifelong medication and the specter of surgical intervention. Yet a growing number of patients in carnivore and ancestral-diet communities report complete symptom resolution—colonoscopies clearing, medications discontinued—after adopting diets centered almost exclusively on animal products.

Patient stories

A woman named Vanessa, in her early thirties, faced a colostomy bag. Her doctors told her they would need to remove part of her lower digestive system due to severe ulcerative colitis throughout her colon. She sought care from Dr. Kyle Loveless, a chiropractor who took spinal X-rays and began adjusting her spine. Four months later—roughly 120 days, the time it takes to regenerate the digestive lining—she underwent a follow-up colonoscopy. The ulcerative colitis had completely resolved. "We have a pre and post colonoscopy of care," Loveless recounts, noting that the initial scan showed widespread inflammation and the second showed a healed digestive system.

One man in his twenties describes a month-long elimination diet that gave him "smooth energy" and stabilized his system. "I stopped coffee and everything, it was really really good," he says. But when he abruptly reintroduced foods—"I was eating like noodles and everything like the first day out of it"—his body rejected the change violently. He received diagnoses of both Crohn's disease and ulcerative colitis in the aftermath. The brief window of dietary discipline had shown him what remission felt like; the relapse taught him what had been driving his inflammation.

A woman with a family history of autoimmune disease was diagnosed with ulcerative colitis during medical school. The condition made it difficult to function during long surgical rotations—ulcerative colitis involves urgent, frequent bathroom trips. When she suggested altering her diet, her instructors dismissed the idea: "No, no, just take the pills." She complied for years, following the standard protocol of immune-suppressing medications and biologics, never questioning whether food might be driving the immune attack on her colon.

One physician, reflecting on his surgical training, describes cutting out colons ravaged by ulcerative colitis. "They died," he says, "and you're telling me if I would have changed the freaking menu? That's the answer." He recalls one death in particular: "He didn't need to die. I didn't even give him that option. I didn't know it." The realization that autoimmune diseases could be reversed—"a guilt that I'll hold for the rest of my life"—came only after he left conventional practice.

The pattern

The dietary intervention these patients converged on eliminates grains, processed sugars, seed oils, and in many cases all plant matter. What remains is meat—particularly ruminant meat like beef—along with eggs, butter, and fatty fish. Some patients adopt a full carnivore protocol; others land on a ketogenic template that includes minimal low-toxin vegetables. Dr. Natasha Campbell-McBride describes working with severe cases of ulcerative colitis and Crohn's using a "no plant GAPS diet," noting that even after years of healing, some patients could not tolerate "the tiniest amount of deeded, peeled, courgette, very well cooked, blended" without triggering diarrhea and vomiting. The mechanisms invoked include removal of plant lectins, which may trigger immune responses and intestinal permeability; elimination of fermentable carbohydrates that feed pathogenic bacteria; and reduction of overall inflammatory load, allowing the gut lining to regenerate.

What the doctors say

Dr. Shawn Baker outlines a stepwise protocol: establish baseline severity, remove "grains, sugars, certainly ultraprocessed foods," then assess after two to three months. "People with inflammatory bowel disease such as Crohn's disease or ulcerative colitis resolve completely their symptoms by using generally an animal-based ketogenic diet or aka a carnivore diet," he states, adding that full symptom resolution can be verified with follow-up imaging and lab work, at which point medications can often be discontinued. Dr. Loveless notes he has seen ulcerative colitis "go away in four months" with chiropractic care aimed at nervous system regulation, arguing that when the body's stress response calms, the gut can heal. Both clinicians emphasize they are not claiming to cure disease, but rather to remove impediments and allow the body's native repair mechanisms to function.

These are case reports, not randomized controlled trials, and the mechanisms remain incompletely understood. But the pattern is striking: patients with a disease conventionally deemed lifelong are walking away from immunosuppressants, seeing clean colonoscopies, and reclaiming years they had written off. The convergence is worth knowing.
