Mr. Wang, 59 years old this year, has been attending a health lecture since a month ago, where so-called "nutrition experts" stated that elderly people can prolong their lifespan by eating only one meal a day and maintaining a sense of hunger.

After returning home, Mr. Wang believed deeply in the words of the so-called experts and only ate one meal every day, no matter how hungry he was. After persisting for more than a month, he thought his body could be better. However, he did not expect to face a serious weight loss and multiple edema in his body. After his son took him to the hospital for examination, he found that Mr. Wang had severe malnutrition.

For Mr. Wang's blind approach to health preservation, doctors say that hunger based health preservation is not suitable for everyone, especially for the elderly. Eating only one meal for health preservation is not worth the loss.

Can starving people prolong their lifespan?

In order to study the relationship between diet and lifespan, scientists have been conducting various life extension studies on animals such as flies, mice, and monkeys since the 1930s. Many animal studies have shown that eating less every day can improve health and prolong lifespan.

National Institute of Aging (NIA) and University of WisconsinTwo studies conducted in the 1980s on rhesus monkeys, which were 93% similar to humans, found that the daily food intake of monkeys decreased by 30%, and the longest lifespan could reach 43 years, which is higher than that of humansLive an average of over 20 years longer.

Additionally,University of Cologne, GermanyA study published in the journal Nature found that in animal models, restricting diet and inhibiting insulin signaling can reverse most age-related changes,10-20%.

Shi Zhengli, Junior Nutritionist in the Clinical Nutrition Department of Beijing Friendship HospitalIt is stated that these experimental results on animals do not necessarily mean that restricting diet in humans can extend lifespan, after all, animals'The average lifespan is much lower than that of humans..

Eating less and exercising more can help lose weight and prolong life, but which one is more effective in prolonging life, two meals a day or three meals a day?

Published onCell MetabolismA study conducted on mice found that the lifespan of mice fed one meal a day was longer than that of mice fed a normal diet11%However, having one meal a day with only 70% of the calories of a normal diet can prolong the average lifespan28%2.
