Why do people want to eat, please 3Q

All animals have to eat, and of course people have to eat. We should also note that the car needs to be filled with gasoline and the fan must be plugged in, otherwise it will not be able to move; We get nutrients from food, and these nutrients, in addition to replenishing our tissue cells, are also burned into calories in our body. Part of this heat is used to maintain our body temperature; The other part is used for the energy we need to exercise and work.

Haven't you heard? It's impossible to want the horses to be good, and to make the horses not eat grass! 1 As the saying goes:

People are iron, rice is steel, and if you don't eat a meal, you will be hungry. "You can say that food is life! If a person goes on a hunger strike, then the consequences can be imagined.

When people are in a good mood, their appetite is greatly boosted, their interest is high, the wind is torn down, they gobble up, and they feast happily; When people are irritable, their appetite is affected, resulting in "unpleasant food and uneasy sleep", which is about a physiological phenomenon controlled by the pituitary gland. Why, it is up to the experts to explain. Food and water are the energy sources you need to survive, and they can be transformed into your life engine.

Without constant replenishment of food and nutrients, your motivation for life will be depleted. You have to think and move every day, and all of this is consuming protein and calories in your body. The digestive system is like a machine that converts the food you eat into your daily protein and calories, so you have to add food to your body every day to get the necessary energy replenishment.

Why do we eat? Because all life consumes energy when it moves, it needs to be replenished. We animals mainly rely on eating organic matter (fish, meat, eggs, milk, hehe) to obtain glucose, which is then converted into energy.

Of course, it is also necessary to ingest a little bit of inorganic matter appropriately. The landlord may have asked, don't plants eat and live well? This is because plants have the ability to directly convert solar energy into chemical energy, that is, through photosynthesis to convert inorganic matter into organic matter, and then use chemical energy into energy to maintain their life activities.

So you don't have to eat to get energy, people can make energy themselves. Speaking of which, the landlord may be asking again, aren't there also insectivorous plants? Nepenthes, sundew, or something.

Here's a conceptual problem to clarify: an insectivorous plant doesn't eat bugs for energy, but to replenish a substance that is lacking in the environment in which it grows. For example, where nitrogen is lacking, it is easy to grow sundew, so you can replenish nitrogen by eating insects, rather than eating insects to replenish energy.

In fact, not only does the sundew not get much energy from digesting insects, but it consumes a lot of energy. Can humans learn how plants live without eating? At present, it is difficult to either humans can absorb sunlight directly; Either you have a reactor in your body that can crack molecules, or you still have to eat honestly.

People don't just eat, but eating is a necessity in human life, eating is the most basic biological activity, as long as living things need to eat. However, we human beings should have more and deeper pursuits, so only when we eat and sleep well and have a good body can we do a good revolution. o(∩_o

People are iron, rice is steel, and there is no hunger for a meal. Isn't it just a matter of making money in today's society? No one can say they don't eat or drink.

It's very simple, if you don't eat, then your life has no meaning, and there is no so-called motivation, eating, sometimes it is a kind of happiness, sometimes it is a need.

If you don't want to breathe, you don't have to eat, and you eat so that you can breathe.

How can people do without food, especially water? Replenish your body's energy!

Eating is for living. , but life is not about eating.

Replenish energy If you don't eat, you starve to death.

To eat, is to live for the next second...

Because I want to, I don't eat it.

If you're hungry, it's hard not to eat.
