There is nothing but the finale of thirty. When Xu Huanshan, who was in prison, looked at Gu Jia with red eyes and said "Let's get a divorce", everyone seemed to breathe a sigh of relief.

Once upon a time, they also loved each other. I remember that Xu Huanshan had fatty liver, and Gu Jia "fasted" him for his health.

The word fasting has been really popular in recent years, and it has almost become a weapon to lose weight in the fashion circle. Is fasting really effective? Is it healthy?

The British documentary "Diet, Fasting and Longevity" reveals that the biggest benefit of fasting to health is not to lose weight, but to fight aging!

In 1930s, a nutritionist from Cornell University conducted a study on food and animals, and concluded that if the food intake of animals is strictly controlled, they will live longer. Since then, there has been relevant research evidence to prove this conclusion.

The mystery may lie in a hormone, insulin-like growth factor type I (IGF- 1).

IGF- 1 is a kind of protein secreted by the liver under the action of growth hormone, and its physiological function is "non-inhibitory islet-like activity" (NSILA).

Walter, the world's most outstanding expert on aging? Professor Longge devoted himself to studying the complex mechanism of controlling aging and exploring the secret relationship between diet and longevity through mouse research.

These transgenic mice have extremely low levels of one hormone, namely insulin-like growth factor type I (IGF- 1). At the same time, these mice are smaller and live 40% longer than ordinary mice.

Fasting can reduce IGF- 1. At this time, cells enter a completely different mode, blood sugar decreases, blood cholesterol decreases, beneficial cholesterol increases, and body damage is repaired.

Mark mattson is an expert in the field of brain aging. His research shows that fasting may delay the arrival of diseases, including Alzheimer's disease, dementia and memory loss.

Mice with indirect energy control can maintain a good state (good learning ability and memory) for much longer than mice with full stomachs. After examining the brains of fasted mice, the researchers found that paroxysmal hunger can stimulate the growth of new neurons. Fasting sharpens animals.

Mark's research concluded that the method of fasting the next day has a more obvious impact on the brain.

What about humans?

The researchers did not eat for three days and four nights, and a burst of hunger struck, and the glucose in the body was exhausted, consuming fat to supply nutrition.

After short-term fasting, the physical examination results showed that IGF- 1 was almost reduced by half.

Professor Luigi fontana of Washington University is studying a group of people who strictly control calories every day.

"They are like another species, they live longer!" The professor exclaimed.

The benefits of fasting also include treating diabetes.

Yale University's research found that eating less can reverse diabetes.

They made a self-made detection method called PINTA (starting from the three main causes of hypoglycemia: glycogen production, glycogen transformation and liver feedback to insulin) to detect the process of liver metabolism and analyze the effects on blood sugar and insulin.

Their one-year research report shows that after eating less staple food, 60% of diabetes is reversed, the risk of heart disease is greatly reduced, and liver function is improved.

The principle is simple: the real cause of diabetes is insulin resistance, and fasting will remove sugar from the body and reduce insulin. Sticking to fast food and adding a small amount of carbohydrates may reverse diabetes.

In the competition study, 630 patients with type 2 diabetes (diabetes duration 0.5~23 years) stopped taking oral hypoglycemic drugs or insulin, then received a very low calorie diet (624 kcal/day) for 8 weeks, and then resumed an equal calorie diet (determined according to resting energy consumption). The study was observed for 6 months.

The study found that after a short-term extremely low-calorie diet, the normal diet was restored, the weight decreased and remained stable, the fat content in the liver and pancreas decreased, and the insulin secretion was improved (see above). There seems to be some scientific basis for fasting or fasting diet.

Of course, the American Diabetes Association also pointed out that the benefits of fasting need to be verified by long-term research, and stressed that its safety deserves vigilance.

It is not advisable to starve completely. At present, light fasting is popular all over the world.

5+2 fasting method

Don't eat for two days a week, either not at all, or eat normally for five days a week, and then choose to eat a small amount of food for two days, with about 500-600 calories a day or simply fast (two bowls of rice).

Fasting every other day

Eat it every other day, and most studies that are beneficial to fasting do so.

Not everyone is suitable for fast food!

Most of the existing fasting experiments are carried out on healthy adults, and no obvious side effects have been observed, but fasting is not necessarily suitable for these people, for example:

Appetite is the hungry wolf in human heart.

Is to do whatever you want until the lamp oil burns out,

Or is longevity a prudence?

Everyone has his own answer. ...
