Intermittent fasting

Intermittent fasting – briefly

Going back to the time of Hippocrates, observers noted that fasting could stop seizures. This led Dr. Russell Wilder to test fasting to treat people with epilepsy.

For some people, “intermittent fasting” means time-restricted eating. This could mean eating only within a specific window of four, six, or eight hours a day, such as noon until eight o’clock in the evening. For others, “intermittent fasting” means occasionally eating nothing for at least twenty-four hours.

This article reviews the book “Fasting Can Save Your Life” by Dr. Herbert Shelton, MD, originally published in 1964. Briefly, you can gain health and build strength without eating. You are nourished not by what you eat, but by what you absorb, assimilate, and excrete. Shelton points out that fasting:

  • is not starvation,
  • gives your digestive system a rest, and 
  • is optimal individually, that is twenty-four hours of drinking water and tea is healthy for some, while fasting for a longer time can be better for others.

The purpose of fasting is to let the digestive system rest, which can improve digestion. Weight loss is a side effect. Dr. Jason Fung, MD, describes fasting as a therapeutic option in this seventy-one minute video.  He includes details in his twelve-minute podcast about fasting and longevity.

Except in Russia, there are few if any clinical trials that prove that fasting works to gain health, but who would sponsor such a clinical trial? Has anybody ever done a clinical trial to prove that water is a cure for dehydration? Is there a clinical trial that proves that prunes have a laxative effect? 

Drs. Longo and Mattson refer to the clinical applications of fasting, particularly for the ageing.

The term “intermittent fasting” can also refer to the practice of limiting the number of hours in the day that you eat. This sort of intermittent fasting restricts eating to a specific window between specific hours of the day, such as noon and eight in the evening, skipping breakfast. This may or may not be practical for you. This gives the digestive system a daily rest of sixteen hours. This method requires self-discipline. I have never tried it myself, but some people enthusiastically claim that it works for them.

Dr. Otto Buchinger and his clinic near Hanover, Germany have been offering therapeutic fasting since 1920.

If you have a medical condition, see a doctor.
