When people feel hungry, is it because there is no food in the stomach, or is there no more calories

When people feel hungry, the main reason is that there is no food in the stomach, so I will talk to you about this problem.

1. Hunger. I believe that everyone knows that the people take food as the sky, in the previous era, basically facing the loess with their backs to the sky, each family will take care of their own one-third of an acre, it can be said that at that time to be able to eat a full meal is also a very happy thing. <>

With the development of the times and the progress of society, our living standards are getting higher and higher, and now we have completely solved the problem of food and clothing, and we have to move towards a higher level of life.

I believe that all animals will have a feeling of hunger if they don't have food, in fact, nature is also a very wonderful thing, with the process of evolution, some of our internal organs are gradually changing.

Cold-blooded animals, such as snakes, can go days without food when they catch it, because the food in their body will gradually digest and provide them with nutrients, and when they go into hibernation, they can go without food for months. <>

2. Diet. I believe that for a person with a more regular lifestyle, three meals a day is the most basic way of eating, in fact, this also forms a biological clock in our brain.

If there is no food entering the stomach during that time, you may feel a feeling of hunger, so you will look for a variety of foods to fill your stomach, and the gastric emptying time is usually about four hours.

The consumption of calories is generally from sugars, fats and finally proteins, which can become our calories, if there are no calories to consume, then it means that we are already in a state of death, so hunger is not this state, but there is no content in the stomach. <>

I hope everyone can eat healthy and have a good routine.

If a person is hungry, the food in the stomach is almost completely digested, and at this time, it will continue to consume calories. Therefore, food should be replenished in a timely manner. In this way, the body can be maintained.

It is because there is no food in the stomach, because there is no food in the human stomach, it will lead to a lack of calories, and there will be hunger, so that the human body will eat food.

Because there is no food, so I feel hungry, and there is a lot of energy in the body, and a lot of fat is stored energy.

When people feel hungry, there is no food in the stomach, and there will be no more energy in the stomach, and if there is no strength, people will feel hungry.

Calories can't provide energy, the heat dissipation is to keep the body temperature constant, as well as the need to maintain the human body, and there is no food in the stomach, then it can't provide the energy you need, the human body needs energy to maintain the amount of exercise, and the maintenance of calories is to better maintain the stability of the body, and the food consumption in the stomach provides the nutrients needed for all parts of the body, and provides the amount of activity required by each part. The starch is broken down into maltose here, then enters the throat and esophagus, goes to the stomach for simple digestion, and then slowly enters the small intestine for digestion, absorbs some nutrients, and then enters the large intestine to decompose and absorb all the nutrients, and then excretes the residue without any nutrients.

In this process, food provides the required energy, provides sufficient power for activity, and also plays an important role in the operation of various organs.

Therefore, when people feel hungry, it is because there is no food in the stomach, there is no substance that can provide energy, calories are needed to maintain basic metabolism, as well as calories needed for exercise, and body growth.

It's not just energy (blood sugar) or just stomach emptying, it's the most direct release of ghrelin. This is a very interesting question, and I like to study this kind of principled nutritional science related to the problem, this time I will analyze the two opposite feelings of hunger and satiety, and the analysis is from the perspective of the hormones secreted by the gastrointestinal tract that regulate the two perceptions.

First of all, satiety and hunger cannot simply be boiled down to energy deprivation or low blood sugar or gastric emptying, as satiety and hunger are very complex mechanisms.

Because if hunger can be controlled by a simple mechanism, such as blood sugar, then the best way to lose weight must be to maintain blood sugar through a specific GI (glycemic index) food, then we must not feel hungry - so keep our mouths shut and no longer worry, obviously this is not valid - so blood sugar is not the only control factor for hunger.

In the same way, gastric emptying and calories can't do this alone. To put it simply: the hormone that controls hunger is ghrelin, but ghrelin itself is regulated by many factors.

One of the most complex is to hedge against hunger of various satiety hormones, because people want to feel full is related to survival, so in order not to be fooled by some large volume and weight but low energy, low nutrition, low-quality food, will evolve a series of hedging factors to interfere with our satiety and hunger.

Hunger is thought to be caused by inadequate food intake, hyperthyroidism, diabetes, duodenal ulcer, etc.

1.Insufficient food intake: Eating less food, insufficient nutrition and relatively large amount of exercise can easily consume calories in the body and cause hunger.

2.Hyperthyroidism: Symptoms of hunger and increased appetite may also occur due to abnormal thyroid secretion.

3.Diabetes mellitus: Appetite can also increase due to unsatisfactory blood sugar control, and frequent hunger is accompanied by symptoms of thirst and polyuria.

4.Duodenal ulcer: Increased gastric acid secretion in the fasting state can cause fasting pain, which can be relieved after entering food, so there is always a feeling of hunger when you want to eat.

In case of frequent hunger, it is recommended to go to the hospital as soon as possible to find out the cause and give ** to avoid delaying the condition.

Hunger is a normal physiological response because the human body secretes a large amount of insulin, and the blood sugar concentration in the blood decreases, resulting in hypoglycemia and hunger. If you are an adolescent, then it is normal for your body to need more energy to grow and eat more food to replenish your nutrients. When the amount of sugar in the body's blood decreases, a person feels hungry.

If you always feel hungry easily, you may have peptic ulcers, diabetes or hyperthyroidism. In patients with peptic ulcers, gastric acid secretion increases, and gastric acid can prompt food to be digested faster, causing hunger. Diabetic patients will have symptoms of fatigue, emaciation, and hunger and overeating due to defects in insulin secretion and/or action, resulting in impaired glucose utilization, increased fat secretion, and negative balance of protein metabolism.

Hyperthyroidism is caused by the increased secretion of thyroid hormones in the blood, which can cause increased nerve excitability and hypermetabolism in the digestive system, and can cause symptoms such as heat intolerance, excessive sweating, weight loss, hyperphagia, increased stool frequency or diarrhea. Patients can have blood drawn to check fasting blood glucose, two-hour postprandial blood glucose, glycosylated hemoglobin, thyroid function, and gastroscopy to confirm the diagnosis.

As the saying goes, why do we eat three meals a day, it's because we're hungry, but is our body really that fun? When the time comes, you will be hungry, and today I would like to talk to you, why do we feel hungry in our human body? <>

The reason is because we need a lot of exercise and calories every day, and after these energy are consumed, they need to be continuously replenished, at this time we will send a signal, that is, we need to eat, that is, why we have to eat regularly, and if you are not eating when you exercise a lot, you will feel hungry, so at this time you will choose some afternoon tea, supper or something. <>

This matter is still up for debate, because there are many girls who will choose to use dieting, the first is that the effect is particularly obvious, and the second is relatively simple, but in this case, it is not recommended that you choose, let yourself keep a long-term hunger, because this will make us malnourished, and then lead to gallstones and some diseases, but in daily life, when we eat, there is a slight sense of union, but it is a good thing for the body, This degree also needs to be grasped by yourself. <

Enjoying food has always been a very beautiful thing, and it is precisely because of this that our lives also have a lot of fun, here, in fact, the impression and everyone is that when we eat something in our daily life, we should also pay attention not to take in too many calories, this will also be bad for your body, in short, how much we eat in our daily life, it is also to be decided according to your own situation, and at the same time, do not overeat, or both a full meal, It's not particularly good for your body, but today I want to say so much about this topic, do you have anything else you want to say? You can leave a message together in the comment area, let's do the event together.

When people feel hungry, they do not burn calories, but only some signals from the body, and when they do not get timely food, they start to burn calories. Hunger is a feeling caused by an empty stomach, and when the food in the stomach is digested, your stomach will feel empty, so you will feel hungry.

Yes, because the body does not have much energy to expend at this time, it will feel hungry. There are no decomposition products in the stomach, and there is no way to better convert them into some glucose, so it will send some information to the brain, and you will feel very hungry.

Yes, because the body doesn't have much energy to expend at this time, you will feel hungry. There's no more breakdown products in the stomach, and there's no way to convert it into some glucose, which sends some messages to the brain and you feel hungry.

It is calorie consumption, hunger is born because of innate energy, and it is also because the body lacks a lot of caloric energy, or after the lack of glucose, you will feel hungry.

Yes, people feel hungry because of calorie consumption, hunger is innate, and hunger is also due to the reduction of caloric energy in the body, resulting in insufficient energy supply to the hypothalamus, but hunger.

Yes, because the calories are consumed, I feel hungry. Because I was hungry for a long time and hadn't eaten, I had a feeling of hunger.

When people feel hungry, it is because there is no calorie, there is no energy for the human body to continue to move, to supply all the consumption of the human body, and people feel weak.

In fact, it is because there are no calories that we feel hungry, and if we eat some chocolate, then we will recover immediately.

It is because there is no food in the stomach, and the nutrition ** is insufficient, which will not make the human body hungry, and thus reduce calories.

When you are hungry, you will feel hungry, and if you have increased saliva secretion, there will be no food in your stomach to digest, and if you don't have food to digest, your stomach will slowly increase, and your stomach will feel uncomfortable.

Just like pain, it is the body's positive guiding response.

The energy of human physiological activity is directly related to the blood sugar. Blood sugar comes from nutrients obtained from food by digestive organs such as the stomach and small intestine, so when the blood sugar concentration drops, it is a normal physiological manifestation for people to feel hungry.

When a person does not eat for a long time, the glucose concentration and fatty acid level in the blood decrease due to continuous consumption; At the same time, the food in the digestive system is gradually digested, absorbed and emptied, which triggers a series of neuropeptide molecules to be secreted into the bloodstream. These signals are perceived by the hypothalamic neurons, resulting in a feeling of "hunger", and the importance of "eating" gradually comes to mind and occupies the whole mind.

No. The body can store a lot of calories. Being hungry doesn't mean you've run out of calories.

Hungry, this is the feeling of the nerve center. We have to eat every day, and the food we eat is usually emptied from the stomach after about 4-5 hours. At this point, the stomach will begin to contract violently.

The time it takes for the stomach to empty is closely related to the composition of the food. If it is purely sugary food, it usually takes about 2 hours to empty, protein food, about 3-4 hours, and pure fat food, about 5-6 hours. Therefore, the average time to mix food is 4-5 hours.

The rate at which the stomach empties is also directly proportional to the amount of food eaten. If there is 100 ml of chyme in the stomach, about 5 ml per minute will be excreted, and when the volume of chyme in the stomach reaches 500 ml, 15 ml per minute will be emptied. Once the contents of the stomach are emptied, the stomach begins to contract.

This is a more violent contraction that originates from the cardia and moves in the direction of the pylorus. This contraction makes the person feel hungry; That is, a signal that you should eat.

We know that there is always a certain amount of liquid and gas in the stomach at any given time. The liquid is generally the gastric digestive juice secreted by the gastric mucosa, and the amount is not too much. As for gas, it is usually swallowed along with food when eating.

In this way, these liquids and gases in the stomach, in the case of violent contraction of the stomach wall, will be squeezed and kneaded, running around, just like when we wash clothes, if there is a certain amount of air wrapped in the clothes, rubbing and rubbing in the water, there will also be a sound of sucking and cooing, which is the same reason.
