How to Eat: A Cure for "Nerves"

In Short

This book is a prescriptive manual for those suffering from "nerves," or what today might be termed chronic stress, anxiety, or neurasthenia. Drawing on his personal journey through two prolonged nervous breakdowns, the author argues that the medical profession’s reliance on complex cures often misses the mark. Instead, he advocates for a radical return to nature: specifically, the habit of chewing food to a cream, avoiding animal proteins and refined sugars, and maintaining a strict regimen of daily outdoor exercise. It endures as a testament to early 20th-century health reform, blending medical observation with the earnest, plainspoken wisdom of a survivor.

The Story

The narrative begins with a stark confession. The author, a physician, describes his descent into a "literal hell" of nervous exhaustion. After enduring a six-month collapse followed by a two-and-a-half-year breakdown, he concludes that modern medicine offers only temporary relief. He recounts his eventual realization that his condition was a form of being "food drunk"—the result of chronic overeating and poor digestion. Driven by a desire to help other sufferers, he maps out a path to recovery that demands total behavioral change.

The argument moves from the physical to the psychological. He insists that the remedy is as ancient as the world: "Whosoever wishes to eat much must eat little." He details the mechanics of his cure, emphasizing the necessity of masticating food until it reaches the consistency of cream to prevent intestinal toxemia. He warns readers that this is not a quick fix; it is a life-long discipline. He shares anecdotes of patients who failed because they treated his advice as a fad rather than a fundamental way of living. He challenges the reader to set aside the "senseless" attachment to weight and comfort, urging them to view themselves as fortunate for being forced to live a more temperate, natural life.

As the argument progresses, the scope expands to include the environment and the spirit. The author argues that diet alone is insufficient without dedicated time outdoors and a return to the habit of "play." He dismisses the idea that one's environment or geography dictates health, pointing to his own travels across the American West as proof. He concludes by addressing the emotional and social hurdles of recovery, noting how difficult it can be for a person to maintain these habits in a household of people who do not share their dietary restrictions. He highlights the importance of temperament, arguing that patience, the avoidance of anger, and the rejection of envy are as vital to the nervous patient as the food they consume. The book ends on a contemplative note, with the author sharing a poem about the inevitability of the "last journey," reminding the reader that while health is a priority, it is ultimately a means to navigate the larger, spiritual questions of life with dignity and grace.

How It Unfolds

The roots of the affliction The author identifies "nerves" as a consequence of chronic over-consumption, comparing the state of the overfed to an alcoholic's intoxication. He dismisses the search for "miracle cures" and asserts that his own recovery came only when he stopped looking for external help and began taking responsibility for his habits.

The mechanics of the cure The central discipline is the thorough mastication of food, which the author calls "Fletcherizing." He explains that while this process may lead to initial weight loss, it is essential for proper digestion and the prevention of the toxic buildup that fuels mental depression.

Refining the diet The author provides specific guidelines, advocating for a lacto-vegetarian approach that avoids eggs and commercial sugar. He uses the examples of high-achieving, long-lived figures like Thomas Edison to illustrate the benefits of eating sparingly.

Integrating life and spirit The final movement emphasizes that diet must be paired with daily, non-violent outdoor exercise and the intentional cultivation of a cheerful, patient temperament. He argues that the recovery of the body is merely the foundation for a life marked by emotional maturity and the avoidance of social poisons like suspicion and greed.

The People

The author, Thomas Clark Hinkle, acts as both the patient and the guide. He is a physician who has transcended his own "horrible suffering" to become a strict, uncompromising mentor. He views himself as a fellow traveler who understands the depths of despair, yet he possesses little patience for those who remain "cowardly" or refuse to put in the work required to heal.

The "nervous sufferer" is the primary audience, characterized as an individual often trapped in a cycle of overeating, mental fog, and failed medical attempts. The author wants these people to see themselves as the "most fortunate" of humanity, provided they can master their appetites and reclaim their health.

The "skeptic" or "nagging companion" represents the resistance. These are the family members or doctors who encourage the sufferer to "eat anything," failing to understand the gravity of the illness. The author uses these figures to contrast the enlightened patient against a society that values "raising beef" over individual vitality.

Finally, figures like Bishop Fallows and Thomas Edison are presented as secular saints of the simple life. They serve as evidence that high-functioning, productive, and long lives are the natural reward for those who practice self-control and avoid the excesses of the common table.

In Its Own Voice

"Whosoever wishes to eat much must eat little."

The author cites the wisdom of Cornaro to establish the foundational principle that longevity is achieved through restraint rather than abundance.

"The trouble with poor deluded mortals--doctors included--is, we are constantly looking for a miracle to cure us, but if we look back on all the real cures that we have ever heard about, we shall find they were as simple as the sun or the rain."

The author critiques the modern tendency to seek complex medical interventions for conditions that require only natural, behavioral adjustments.

What It's Really About

At its heart, this book is an argument for self-sovereignty through the body. It posits that "nerves" are not an external misfortune but a direct byproduct of a life lived out of alignment with nature. The author explores the philosophical question of whether happiness is found in consumption or in the mastery of one’s desires. By framing the act of eating as a moral and physical discipline, he suggests that modern illness is essentially a failure of character and common sense. The work asks the reader to consider the cost of convenience and the immense power found in the simple, deliberate acts of chewing, moving, and choosing what to consume.

Why Read It Today

Readers interested in the history of medicine or the origins of modern wellness movements will find this a fascinating, if occasionally idiosyncratic, artifact. It provides a window into a period when doctors were grappling with the rapid onset of modern industrial stress and attempting to find solutions that didn't rely on the burgeoning pharmaceutical industry. The tone is bracing; it feels less like a clinical textbook and more like a stern lecture from a grandfather who has seen the worst of the world and wants to save you from it.

One must be prepared for the author’s bluntness. He is dismissive of mainstream medical advice and occasionally veers into prescriptive territory that modern science would qualify or reject. His attitude toward "cowardly" suicidal thoughts or his rigid dietary advice reflects the sensibilities of 1921, which may feel harsh or overly simplistic to a contemporary reader. However, the book’s insistence on the connection between mind and gut remains strikingly relevant. It is a slow, methodical read that requires the same patience the author demands of his patients. You will likely walk away not with a new pill, but with a heightened awareness of how the frantic pace of modern eating affects your own sense of calm.
