“After 1.5 years on an animal-based diet eating only meat, eggs, fruit, and fermented foods, a man named Lachy Oliver put his Crohn's disease into remission without the help of any doctors." (Instagram, @paulsaladinomd, 2026-10-24. Accompanying claims: hsCRP fell from 75 to 0.4; psoriasis, anxiety, brain fog, low energy resolved; ADHD,…”
Plain restatementAn individual reports that, after about 18 months eating only meat, eggs, fruit and fermented foods, his previously diagnosed Crohn's disease entered remission and his inflammatory marker normalised, without medical treatment. The post presents this single self-reported case, plus a second self-reported case of multiple sclerosis improvement, as evidence that diet can reverse chronic autoimmune disease generally.
General information only - not medical advice.
Lachy Oliver is a real person and he really does say this about himself, in podcasts and on his own coaching website. What cannot be checked is the medical substance. There is no published case report, no diagnosis confirmation, no endoscopy result and no lab record anywhere in the public record, so the story is an unverified personal account from someone who now sells coaching based on that diet. The wider message in the post is weaker still. The researchers who published the main supporting paper on carnivore diets and inflammatory bowel disease state that no rigorous trials of this diet for IBD exist, and their own study only included people for whom the diet had already worked. Crohn's disease also improves on its own in roughly one in ten to one in five people given a placebo in trials, which is why one person's recovery cannot show that the diet caused it. The claim that someone's multiple sclerosis lesions all vanished on a meat diet is not supported by any evidence, as no diet has been shown to clear MS lesions. Diet genuinely does matter in Crohn's, and some dietary therapies are guideline-recommended, but those are supervised approaches used alongside medical care rather than instead of it, and anyone considering stopping prescribed treatment should discuss it with their own clinician first. General information only, not medical advice.

Red-tinted words in the claim drifted from the evidence. Green-tinted words are what a neutral restatement needs.
The trace / claim to source
- Lachy Oliver is a real person who has publicly and consistently told this story across multiple podcasts and his own business platform. The post accurately reports what he says about himself.
- Diet is a legitimate therapeutic lever in Crohn's disease. Exclusive enteral nutrition is a guideline-endorsed first-line induction therapy, and structured exclusion diets have trial evidence.
- Elimination-style diets can reduce symptoms in some people with IBD, and a small published case series reports symptom improvement and medication cessation on carnivore or ketogenic diets.
- Very high CRP values are consistent with active inflammation, and CRP can fall substantially when Crohn's inflammation subsides, by whatever mechanism.
- Drug-free remission in Crohn's does happen. That part is not implausible on its face.
- Unsupported causal inference. The post treats temporal sequence as proof of cause. Crohn's relapses and remits naturally, with placebo-arm remission rates of roughly 10% to 22%. A single case with no control cannot separate diet from spontaneous remission.
- Generalisation from n=1 to a population. "You can reverse these diseases" and "send this to somebody suffering with Crohn's, ulcerative colitis, or multiple sclerosis" extrapolate one unverified anecdote to entire disease populations. The carnivore literature itself concedes that no rigorous interventional trials exist.
- Selection bias presented as evidence. The supporting case series recruited by social media and included only people who had already responded to the diet. "I've seen this hundreds, if not thousands of times" is survivorship bias: people whose diets failed do not make videos.
- Omitted qualifier on "remission." Clinical or symptomatic remission is not the same as endoscopic or histologic remission. Crohn's can progress silently while a person feels well. No objective remission evidence is presented.
- Marketing as evidence. Both the subject and the poster sell products and coaching built on this dietary framework. That is not a reason to dismiss the account, but it is undisclosed in the claim as framed.
- Unsupported specific medical claim on MS. "10 out of 10 lesions vanished" is presented as a diet outcome. No dietary intervention has been shown to clear MS lesions, and the certainty of evidence on diet and MRI lesions is very low. No MRI reports are offered.
- Care substitution framing. "My doctor said I need surgery and medication for the rest of my life. So I never went back" and "before you accept a lifetime of medications" position diet as a replacement for monitored care. Crohn's is a condition where untreated inflammation can cause structural bowel damage, and gastroenterology guidance treats dietary therapy as something delivered alongside clinical monitoring, not instead of it.
- Conflation of unrelated outcomes. ADHD, testosterone, iron, anxiety and brain fog are bundled with Crohn's remission as if one mechanism explained all of them. Nothing in the retrieved evidence supports that bundling.
- Whether Lachy Oliver's Crohn's diagnosis was histologically confirmed. No record found.
- Whether his remission was objectively confirmed by endoscopy, calprotectin or imaging, or is symptom-based only. Not found.
- The hsCRP values of 75 and 0.4, including units and assay. These appear only in self-report. Not independently documented.
- Whether he had any prior or concurrent treatment, and how recently any medication was stopped before the diet began.
- Whether the remission has been sustained beyond the reported 18 months.
- The identity, diagnosis and imaging history of the anonymous MS commenter. Entirely unverifiable.
- Whether his lipid profile changed, which the published carnivore case series flags as a genuine concern.
Lachy Oliver is a real, identifiable person who has told this story publicly and repeatedly. A podcast episode page describes sitting down with coach Lachy Oliver to hear his story of overcoming Crohn's disease, anxiety, ADHD, and burnout without medication, and states that after years of struggling with his health he turned to an animal-based diet, went into remission within months, ran a marathon, and saw his mental health transform. Other appearances describe the same account, including his personal battles with Crohn's disease and ADHD, and how he overcame alcoholism. He now runs a commercial coaching business: BHUMAN, founded by Lachy Oliver, provides personalised ancestral coaching designed to restore gut health, support sustainable fat loss and improve energy, focus and performance. No independent clinical documentation of the case was located: no published case report, no physician-authored write-up, no endoscopy, histology or laboratory records in any retrievable source. Everything traces to the subject's own account, relayed through podcasts, social media and his own business site. On the general proposition, the carnivore literature is explicit about its own weakness. The 2024 Frontiers in Nutrition case series states: "To date, there have been no rigorous interventional trials on KD or carnivore diet for IBD, including UC and Crohn's disease." That paper is itself an uncontrolled, self-selected series: participants were recruited through a social media survey, and final inclusion required a histologically confirmed diagnosis of UC or Crohn's disease that was responsive to a ketogenic or carnivore diet without medication or with successful medication cessation on the diet. In other words, it selected only people for whom the diet appeared to work. Its results were self-reported questionnaire scores: 10 cases of IBD responsive to ketogenic, mostly carnivore diets, six UC and four Crohn's, with clinical improvement scores ranging between 72 and 165 points on the IBDQ, patients eating mostly meat, eggs and animal fats. The same series also recorded marked lipid elevations in at least one patient: total cholesterol 479 mg/dL, LDL-C 399 mg/dL. What guidelines do support is a different dietary therapy. The AGA states that exclusive enteral nutrition using liquid nutrition formulations is an effective therapy for induction of clinical remission and endoscopic response in Crohn's disease, and exclusive enteral nutrition is recommended as a first-line therapy to induce remission of Crohn's disease and is considered as effective as corticosteroid treatment. Structured exclusion diets have also been trialled: the Crohn's Disease Exclusion Diet, which avoids products thought to have a pro-inflammatory effect on the intestinal mucosa, shows similar effectiveness to EEN for inducing remission in paediatric patients, and was evaluated in 32 adult patients. None of these are an all-meat or animal-based diet. Crucially, Crohn's disease remits on its own at a meaningful rate, which is why single anecdotes cannot establish causation. A pooled analysis found a placebo remission rate of 18% (95% CI, 14% to 24%; median 19%), and a more recent individual-patient-data meta-analysis reported overall placebo clinical response and remission rates of 27% and 10% for induction, and 32% and 22% for maintenance, using data from eight induction and four maintenance trials. On the secondary MS claim, no dietary intervention has demonstrated lesion clearance. An academic MS centre states plainly: no specific diet has been proven to prevent relapses, reduce MRI lesions, or stop disability progression, though overall diet quality may play a role in day to day wellbeing. An umbrella review of dietary interventions in MS found the certainty of evidence to be very low even for the most-studied interventions, noting that systematic reviews applying GRADE classified findings from RCTs of vitamin D supplementation as "very low" certainty regarding effects on disability and MRI lesions.

Ask this case
Answers come only from the case file above; nothing is added.
Is Lachy Oliver a real person, and did he really say this about himself?
Yes. He is a real, identifiable person who has publicly told this story about his Crohn's disease across multiple podcasts and his own coaching business site. The post accurately reflects what he says about himself.
Is there medical documentation confirming his diagnosis, remission, or lab results?
No. The investigation found no published case report, physician write-up, endoscopy, histology, or laboratory records. Everything traces back to his own personal account relayed through podcasts, social media, and his business site.
Does science support an animal-based or carnivore diet treating Crohn's disease?
Not through rigorous evidence. The main supporting study itself states that no rigorous interventional trials of ketogenic or carnivore diets for IBD exist, and it only included people for whom the diet had already appeared to work, which introduces strong selection bias.
Could his remission have happened without the diet causing it?
Yes, that is possible. Crohn's disease is known to remit on its own in a meaningful share of cases, with placebo-arm remission rates in trials ranging from about 10% to 22%. A single uncontrolled case cannot distinguish diet effects from spontaneous remission.
What about the claim that a second person's MS lesions vanished on this diet?
The investigation found no evidence to support this. Medical sources state plainly that no specific diet has been proven to clear MRI lesions or stop MS progression, and evidence on diet's role in MS outcomes is rated very low certainty.
