Hara hachi bu

Template:Nihongo, or hara hachi bunme (and sometimes misspelled hari hachi bu), is a Confucian[1] teaching that instructs people to eat until they are 80 percent full.[2] Roughly, in English the Japanese phrase translates to, "Eat until you are eight parts (out of ten) full".[2] or "belly 80 percent full".[3]

Okinawans

As of the early 21st century, Okinawans in Japan, through practicing hara hachi bu, are the only human population to have a self-imposed habit of calorie restriction.[2] They consume about 1,800[3] to 1,900 calories per day.[4] Their typical body mass index (BMI) is about 18 to 22, compared to a typical BMI of 26 or 27 for adults over 60 in the United States.[5] Okinawa has the world's highest proportion of centenarians, at approximately 50 per 100,000 people.[6]

Biochemist Clive McCay, a professor at Cornell University in the 1930s, reported that significant calorie restriction prolonged life in laboratory animals.[7][8] Authors Bradley and Craig Wilcox and Makoto Suzuke believe that hara hachi bu may act as a form of calorie restriction, thus extending practitioners' life expectancy. They believe hara hachi bu assists in keeping the average Okinawan's BMI low, and this is thought to be due to the delay in the stomach stretch receptors that help signal satiety; The result of not practicing "hara hachi bu" is a constant stretching of the stomach which in turn increases the amount of food needed to feel full.[2]

Influence

In the 1965 book Three Pillars of Zen, the author quotes Hakuun Yasutani in his lecture for zazen beginners as telling his students about the book Zazen Yojinki (Precautions to Observe in Zazen), written circa 1300, which advises practitioners to eat about two-thirds of their capacity. Yasutani advises his students to eat only eighty percent of their capacity, and he repeats a Japanese proverb: "eight parts of a full stomach sustain the man; the other two sustain the doctor".[9]

Hara hachi bu was popularized in the United States by a variety of modern books on diet and longevity.[10][11][12]

Featured disease

Metabolic syndrome is a cluster of the most dangerous heart attack risk factors: diabetes and prediabetes, abdominal obesity, high triglycerides, low HDL cholesterol and high blood pressure.

Affects one in three adults

Affecting about 35 percent of all adults in the United States according to the CDC, metabolic syndrome contributes to weight gain, by causing a state of internal starvation called metabolic starvation. This in turn leads to increases hunger, sugar cravings and increased portions leading to overeating and weight gain.

Cause and effect misunderstood

Since we traditionally thought that the portion control (which in turn was attributed wrongly to poor will power)is the cause of weight gain, rather than the effect of this metabolic starvation, all our traditional ideas about cause and effect of obesity were not only wrong but lead to the “blame the victim” attitude when it comes to obesity.

Secret of weight gain revealed
