Rational Fasting For Better Health

Understanding the concept of rational fasting and doing it correctly can help us live a healthier life with respect to our physical, mental and spiritual well being. In this modern world, we often hear a lot of myths about fasting and its effectiveness. But the reality is that people have been fasting to get better health throughout the history. In this article we will learn about rational fasting and rational weight loss along with various other practical tips for better health.

What is Rational Fasting and how does it contribute for better health?

Let’s start with the following book, Rational Fasting, by Arnold Ehret:

Arnold Ehret (July 29, 1866 – October 10, 1922) was a German naturopath and alternative health educator who created the Mucusless Diet Healing System.  Ehret wrote books and articles about detoxification, fruitarianism, fasting, food combining, health, longevity, naturopathy, physical culture, and vitalism, among other topics.

Despite medical science’s assertion that white blood cells are essential components of the immune system, Ehret felt that white blood cells are created by eating mucus-forming foods and pollute the blood as waste materials. This is still today a controversial topic but let’s not forget the great breakthroughs in our history has always been counter-culture in the first place.

Schleimlose” (slime-free) foods were the key to human health, according to Ehret, who defended that “fasting (just eating less) is Nature’s omnipotent means of purifying the body from the effects of improper and too much eating.”

After rejecting the nitrogenous-albumin metabolic theory in 1909, Ehret discovered a contemporary, Thomas Powell M.D., in 1912, who shared his belief that “grape sugar” (simple sugars found in fruits and vegetables) was the best fuel source, body building material, and source of vital energy for humans, rather than protein-rich foods. Powell outlined his thoughts in the 1909 book “Fundamentals and Requirements of Health and Disease.”

Humans’ natural diet, according to Ehret, consisted of alkaline foods that were also mucus-free.

Ehret claimed that the body is an air-gas engine that does not require food for energy, and that it was not built to use mucus-forming meals, using the equation Vitality = Power Obstruction (V = P O) as proof. The lungs, according to Ehret, were the body’s pump, while the heart served as a valve, with the blood controlling the heart.

Metabolism Myth?

According to Ehret, new tissue is formed mostly from simple sugars found in fruits, rather than protein and fat-rich diets. During the transition to the ideal fruit diet, Ehret favored only nuts and seeds, and even then, only “in moderation,” condemning high-protein and fat-rich foods as “unnatural,” writing that “no animals eat fats” and that “all fats, even those of vegetable origin, are acid forming and are not used by the body.”

Later editions of Fred S. Hirsch’s Mucusless Diet Healing System stated nuts were “mucus-free.” Meat, eggs, milk, lipids, grains, legumes, potatoes, and rice were among the foods Ehret avoided, but he recognized the transitory significance of some of them. Fats and proteins, according to Ehret and his contemporary, Ragnar Berg, are acid-forming and should be ingested in moderation.


Rational Fasting is a nutrition therapy that has been adopted by many other medicine professionals. In general, the protocol involves complete abstinence from food for a period of at least 11 days up to 40 days (or longer, if needed). Instead of solid food, only plant-based caloric fluids which contain no protein nor fat are allowed during this treatment: fruit juices (preferably freshly squeezed from ripe organic fruits) and plant broths/infusions with water in the proportion of 3:2 (juices:water).

Juices, broth/infusion and water can be consumed in unlimited amounts, as long as no solid food is ingested. Rational Fasting does not require starvation; all sources of energy are provided by the nutrients of the fruit juices and broth/infusion. While fasting, patients should sleep 2 to 3 hours in between each juice intake; ideally in their own bed or couch instead of their desk at work or while on an airplane.

Also recommended during this time are baths with ozone, sunbathing and sauna to promote sweating and excretion of impurities via the skin which would otherwise have been eliminated through the bowel movements during fasting.
