There is a law called “eat at night”.
Specifically:
At night, it’s like some magical magic that secretly turns on the “appetite” switch of the body.
Why do you want to eat more at night? Is self-control too bad?
Scientists believe that you are not to blame for wanting to eat.
They suspected that it would make people want to eat more at this time of the night.
Researchers at Harvard Medical School found 12 healthy adults who were neither thin nor fat, and asked them to stay in the experimental environment for 13 days. They not only strictly controlled their activities, calories and nutrition of three meals, but also controlled the ambient lights. Then, they observed whether their appetite would be affected by time.
The results showed that around 8 p.m. biological time, everyone’s appetite and hunger will be stronger!
If you’re a stay up star, 8:00 p.m. in the picture,
Maybe it’s your 10:00 or 11:00
In addition, the researchers also found that the subjects’ appetite for sweet, salty, starch foods and meat also showed the same trend, except for vegetables… They never wanted to eat much.
If you want to eat at night and only want high calorie food, it may not be that you are not determined, but that your body feels that it is time to eat.
Behind this, it may be that “hunger element” is making trouble.
There are many mechanisms regulating appetite, and one of the most important mechanisms is the “central nervous system regulation mechanism”.
The commander of this mechanism is the hypothalamus at the bottom of the brain. After receiving signals from all over the body, the hypothalamus controls the release of some chemicals to regulate our appetite.
One of the most representative signals is ghrelin, which is a hormone mainly secreted by the stomach. After activation, it is very important to promote appetite.
When we see fried chicken, string, milk tea, hot pot and cake, the hunger hormone in the body will increase, stimulate the “orexin system” in the brain, and make people reach for food involuntarily.
What’s more annoying is… This evil hormone has a more evil feature: it secretes more at night.
The experimental team of Brigham and women’s Hospital of Harvard University once recruited 14 volunteers who were in good health. Their blood samples were taken 7 minutes before meal, 1 hour and 2 hours after meal to measure the concentration of ghrelin.
The results showed that the levels of ghrelin at night were higher than those during the day.
Having said so much, you should understand that the next time you are dominated by a strong appetite late at night, you can recite this sentence silently:
