Starving to Heal in Siberia

Michelle B. Slater · 2022

Thesis

After years of late-stage Lyme disease that no conventional or alternative treatment relieved, Slater recovered through supervised dry fasting, going without food and water, in Siberia, and she argues that fasting lets the body clear damaged and infected cells in a way that could help others with chronic illness.

Strength of evidence: tradition and practice-based. The book is a single patient's account and a practitioner's protocol; there are no controlled trials of dry fasting for Lyme disease, and prolonged dry fasting carries serious medical risks.

The main ideas

Slater, a literature scholar, was disabled for years by late-stage Lyme disease that every treatment she tried failed to relieve.
She found Dr. Sergey Filonov, a Siberian physician who treats chronic illness with dry fasting: no food and no water.
Under his supervision she built up from 36 hours to a nine-day dry fast, and later fasted again on her own.
Filonov's theory is that inflammation drives chronic illness, and that in a fast the body consumes its own damaged and infected cells.
She reports a complete recovery and argues the practice deserves attention from Western medicine.
The book includes a protocol, but reviewers judged dry fasting dangerous without close medical supervision.

A very sick patient

Michelle Slater, who holds a PhD in French literature from Johns Hopkins, describes years of late-stage Lyme disease, a tick-borne bacterial infection. Her symptoms were extreme chronic fatigue, brain fog and joint pain, severe enough that she could no longer teach, read or drive.

She tried, in the publisher's words, every known treatment, from aggressive conventional medicine to holistic remedies, and none worked. The second chapter is titled "The Alternative Was Assisted Suicide": she had reached the point of considering ending her life.

The book's first part, "A Very Sick Girl," traces the illness through a timeline of vignettes and ends, after a chapter titled "Convincing D," with her decision to travel to Siberia.

The account matters to the argument because it establishes the stakes. Slater presents dry fasting not as a first choice but as what she turned to after exhausting everything else, and her willingness to accept its risks follows from how little she felt she had left to lose.

Implication: read the book as the record of a last resort, chosen by a patient for whom standard treatment had failed, and judge its recommendations in that light.

Dry fasting in Siberia

Slater learned about dry fasting from an article, and found Dr. Sergey Ivanovich Filonov, who treats patients with it in Siberia and wrote the book's foreword. A dry fast excludes all food and all liquids, including water.

Her treatment began with 36 hours without food or water. Each fast after that was longer, until she completed a dry fast of nine consecutive days, the subject of the chapter "My Nine-Day Dry Fast under the Siberian Sun." She spent about two months in Siberia under Filonov's supervision. After returning home she completed another round on her own.

The middle part of the book, "Starving to Heal," also records Filonov's lectures and his outlook, summarized in a chapter title: "The Body Is the Doctor." She describes the period after a fast, when eating resumes gradually, as recovering from "natural surgery."

The mechanism, in the book's account, is supervision and gradual extension. Each fast is longer than the last, and the doctor monitors the patient through it and through the return to food.

Implication: the protocol Slater followed was gradual and medically supervised throughout; the book offers no basis for attempting a prolonged dry fast without that supervision.

Recovery

Slater reports that she recovered completely. Her memory returned, and she went back to the work the illness had taken from her, research and writing, and to physical activity, hiking and running. The book's epilogue and its title's subtitle, My Radical Recovery from Late-Stage Lyme Disease and How It Could Help Others, present the outcome as the reason for writing: a treatment that worked for her, she argues, should be known to others with chronic illness who have run out of options.

The mechanism she credits is the fasting itself, as Filonov explains it: with outside food and water removed, the body turns to clearing what is damaged or infected. She presents her recovery as a test of that idea in the case she knew best, her own.

Implication: take the recovery as a reason to ask whether supervised fasting deserves clinical study for chronic illness, not as evidence that it works; one patient's improvement cannot show what caused it.

The body is the doctor

Filonov's theory is that inflammation drives chronic and autoimmune illness, and that fasting removes its causes. During a fast, the body, deprived of outside food, consumes its own damaged and infected cells. The cellular process is autophagy, literally self-eating, and Slater connects Filonov's practice to the work of Yoshinori Ohsumi, who won the 2016 Nobel Prize in Physiology or Medicine for discovering how autophagy works.

The third part of the book, "The Science of Fasting," develops the argument. One chapter calls autophagy the fountain of youth within. Another, "The Challenge of Autophagy in a Chemical World," discusses how modern environments burden the body. A guide to dry fasting follows. Appendices give a fasting protocol, medications used during dry fasting and recipes for eating afterward.

The book's argument for wider use rests on this mechanism. If fasting triggers the body's own repair, Slater argues, it should be studied and offered for chronic illness, where Western medicine has treated fasting mainly as a tool against aging rather than as a cure.

Implication: autophagy is a real and well-studied process, but its existence does not show that prolonged dry fasting treats any particular disease; that requires trials that have not been done.

Limits

Library Journal found the book well written and organized but judged that it gives instructions for a dangerous practice that should not be attempted as self-help, and called providing them irresponsible. Depriving the body of water for long periods risks dehydration, kidney strain and electrolyte imbalance, and almost all research on dry fasting covers the twelve to sixteen hours of a Ramadan fast, not days.
The evidence is one patient's recovery. There are no controlled trials of fasting, dry or otherwise, for Lyme disease, and a single recovery cannot separate the effect of the fast from the natural course of the illness.
Persistent Lyme symptoms are contested. The Infectious Diseases Society of America finds no reliable evidence of chronic infection with the Lyme bacterium after standard treatment, though some 10 to 20 percent of treated patients have lasting symptoms, termed post-treatment Lyme disease syndrome.

How Not to Die — diet, rather than abstinence from food, as the main lever against chronic disease.
The Good Gut — the microbial side of what and whether we eat.
