What Made Arnold Ehret a Successful Book Author

Arnold Ehret was a German health educator. He was also an author of several books on various topics. The main subjects of his books and cornerstones of his life include naturopathy, detoxification, health, food combining, diet, physical culture, fasting, fruitarianism, longevity, and vitalism.
Clearly, Ehret’s background, values, teachings, experiences, religious beliefs, scientific claims, legacy, and views on disease played a role in making him a successful author.
He also loved fasting, meaning he spent most of his time outdoors in nature because ventilation is outside. Modern writers and authors have lots to learn from Ehret. For instance, they spend more time outdoors to relax, fast, appreciate life, and get inspiration for writing ideas.
This makes it necessary to consider modern outdoor appliances such as tankless outdoor water heaters you can use to set your temperature right for taking hot showers after spending your time outdoors.


Ehret founded vitalism in dietetics and championed Ehretism. He related the human body to an “air-gas engine” powered by oxygen. He also claimed that “mucusless” foods, a diet comprising of starchless veggies, fruits, and edible greens or herbs are the optimum food humans should consume.
He believed that the condition of the milieu interior, a principle, and term that Louis Pasteur formed earlier, influenced human health. He wrote a book titled “The Mucusless Diet Healing System” to demonstrate that mucusless foods were the gateway to attaining optimal health.


Fred and Lucille Hirsch published the literature that Ehret authored for over six decades. The torch symbol on his books became the Ehret Health Club’s logo. The Ehret Literature publishing Company based in New York took over his publications in 1979.
The New York-based company also inherited his archive of German manuscripts that were yet to be published. The manuscripts were written on a natural diet, nature cure, metaphysics, history, spirituality, religion, physiology, Nietzsche, and philosophy.
Manuscripts “About The Healthy Human” and “The Ascona Lectures” were also inherited. The archive also included a poem of 5 stanzas titled “Ehretism”. It was published on the Breathairean Ensemble website. In the archive was also a photo of Albert Einstein with Fred Hirsch.
A German professor at Oregon’s Willamette University in Salem, Dr. Ludwig Max Fischer, translated the book “Kranke Menschen” written in German into English, in 2002. The professor was an avid follower of the teachings of Ehret.
The book contained his new photos, including birth and death certificates. It also featured October 8th’s Los Angeles Times advertisement that marketed his final “free lecture”.

Views on disease

Ehret associated human disease with foods responsible for forming mucus and pus. And, he taught that slime-free (schleimlose) foods were the gateways to human health.
Fasting is Nature’s omnipotent way of cleansing the human body to protect it from too much or wrong eating.
Mucus is a glycoprotein acid. The term was obtained from the Greek word “myxa”. William Cullen referred to mucus as “butyraceous matter.” And, Gustav Schlickeysen mentioned a layer of mucus found under the skin in Obst and Brod.
Dr. Teofilo De La Torre later termed the word “mucin” in the 50s. In the 60s, Morris Krok coined it “mucous”. Norman Walker used it in ‘impacted fecal matter’ in the 70s. In the 80s Robert Gray used ‘mucoid matter’ and ‘mucoid plaque’ in the 90s.
Daniel Reid re-introduced the term ‘mucus’ in the 2000s. Gray distinguished unhealthy and healthy mucus to further differentiate them.



Ehret lived in Freiburg in 1907. He visited Ascona’s nature life colony located next to Lake Maggiore known as Monte Verita. Other visitors included Trotsky and Lenin.
He collaborated with the owner of a sanitarium at Monte Verita who was called Henri Oedenkoven. Afterward, he opened his own sanitariums: “Fruit and Fasting Sanitarium” in Massagno (Lugano) and another in Switzerland’s Ascona area.
He treated thousands of patients who were diagnosed with incurable diseases at the sanitariums. And, he authored one of his books in Locarno. He took part in several fasts and public lectures that Swiss and German officials monitored, in 1909.
Ehret fasted for more than 126 days without eating anything within a duration of 14 months. He had previously done multiple fasts of 21, 24, 32, and 49 days, totaling 120 days. A Royal Court notary supervised the fasts.
He wrote an article for a vegan German magazine in 1910. It was about his experience during the 49 days fast, something that gained the interest of the public. The article was later included in his book titled “Lebensfragen”, meaning life questions.

Scientific beliefs or claims

Ehret found out about Thomas Powell M.D., a contemporary, in 1912, who agreed with his claims that simple sugars in fruits and veggies (grape sugar) were the optimum of human health. In 1909, he had denounced the metabolic theory of nitrogenous-albumin.
He believed that “grape sugar” was the best source of fuel, an agent of vitality, and body-building material for humans, and not foods rich in protein content.
According to Ehret, alkaline or mucusless foods made up human beings a natural diet. Julius Hensel, a chemist, and Ragnar Berg, a Swedish chemist, concurred with his findings of food and pH values
