Why do you want to eat in winter and have no appetite in summer?

Why do you have a big appetite in winter?

The body needs to replenish energy to resist the cold.

In winter, the temperature drops. In order to keep warm, our bodies will want to consume more calories to maintain their body temperature, so they will eat more food to meet their energy needs. At the same time, in order to maintain body temperature, the body's metabolic rate will increase and energy consumption will be faster, which will make the body feel hungry more easily and make you want to eat more.

Cold weather can easily promote gastric acid secretion.

Do you know that?/You know what? Do you know that?/You know what? In our blood, there is a substance called histidine, which has a great relationship with gastric acid secretion. When the weather gets cold and the human body is stimulated by cold, histidine in the blood increases, which leads to a large increase in gastric acid secretion, thus stimulating appetite and making us want to eat more in winter!

In winter, when outdoor activities are reduced, people tend to stay at home and stay indoors. At this time, they will pass the time by eating. This will unconsciously eat more food and increase people's appetite.

It can be seen that there are many reasons why people have a big appetite and want to eat more in winter.

The real hunger we are talking about is that the body sends a hunger signal to remind people to eat. The simplest hunger is growling or dizziness. This situation belongs to the hunger faced by the body.

In view of this situation, we should eat food, and don't eat too fast and chew slowly when eating. At the same time, the food in winter is often mainly high-calorie meat, and some vegetables are also needed. For young women who want to control their figure, it is best to combine foods with high dietary fiber content and eat them together. Such a diet can make the body feel full and slow down hunger.

Loss of appetite in summer is mainly due to the following reasons: 1. After the hot weather, the basal metabolic rate of the human body is low and less calories are needed. Besides being used by the body, most of the heat generated by food intake is discharged with sweat or skin, so the appetite of future generations will decrease in hot weather. 2. After the hot weather, intracranial blood vessels expand due to high temperature, and the hormones secreted by hypothalamus will also change. Its hormones can inhibit the appetite center of the brain, leading to a decline in appetite. 3. The increase of temperature will inhibit the secretion of digestive enzymes in the stomach. Decreased secretion of digestive enzymes will lead to slow digestion and peristalsis of gastrointestinal tract, which will appropriately increase the satiety of human body, thus leading to decreased appetite. 4, mood factors, hot and humid weather in summer will affect people's mood, leading to irritability and affect appetite.
