Why are you not so hungry when you are hungry? Starvation is harmful to your health

everyone may have such an experience: sometimes because you are busy with work or other things, even if you feel hungry, you don’t want to delay, so you & lt; Starvation & quot;, Finally finished, but suddenly found that not so hungry. Why?

there is a saying that people’s feeling of taste, temperature and even hunger is in daily life; Hunger Control & quot; If you can save food, you can lose weight, and you don’t have to be busy all the time; Abuse & quot; Your own excuse, health is the most important.

how much we eat every day is controlled by the ventromedial nucleus (also known as satiety center) and ventrolateral nucleus (also known as starvation center or feeding center) in the hypothalamus of the human head.

under normal circumstances, the process of human food intake is carried out through the neural regulation mechanism among gastrointestinal tract, satiety and hunger center, and cerebral cortex. We are in a state of mutual regulation, mutual restriction and relative balance.

when the cerebral cortex feels hunger (the gastrointestinal tract sends out fasting signals), the central will send eating (exciting) instructions to the feeding center, and send inhibitory instructions to the satiety center, so as to start eating;

after eating a certain amount of food, the gastrointestinal tract will send the signal of satiety to the brain and satiety center through nerve reflex, and the cerebral cortex will send the command of satiety to the satiety center and the feeding center respectively to stop eating. Of course, food with color, aroma and taste can leave people with the idea of having a good meal through our visual organs, and transmit this information to the hypothalamic center.

when to eat every day, or how much to eat per meal, is often related to personal lifestyle and habits. Many obese people with a family history of obesity often have the habit of overeating. Their eating habit is not because of hunger, but just a habitual repetitive action. It’s just like when people see food with all kinds of color, fragrance and taste, whether they are hungry or not, they can’t help tasting it.

animal experiments found that after the destruction of the ventromedial nucleus (satiety center), the animals lost the sense of satiety and continued to eat, the amount of food intake increased significantly, and the animals showed obvious obesity. And this kind of weight gain, has to develop to a certain extent, when the body reaches a new energy balance will stop. This can also explain why some patients with encephalitis and meningitis sequelae have symptoms of overeating and obesity. One possible reason is that the ventromedial hypothalamic nucleus of these patients has problems. If the starvation center of hypothalamus is destroyed in the experiment, the animal will lose the sense of starvation and refuse to eat for a long time, and finally die of failure.
