Adult basal metabolism

Basal metabolism is an extremely important thing for the human body. It is closely related to the functioning of people's organs. The basal metabolism of adults is different from that of children. People also need to understand what the normal basal metabolic value is, so as to avoid problems with basal metabolism and bring adverse effects to people's bodies. The following is a detailed introduction to the normal basal metabolic value for adults.

The basal metabolic rate is the minimum amount of calories required to maintain the functioning of the body's vital organs. It rarely changes in the short term and is almost determined in the genes. However, it tends to decrease with age. Generally speaking, a person's basal metabolic rate is quite high during infancy, decreases rapidly during childhood, and gradually stabilizes after adulthood. The average human body needs to consume at least 1000 calories a day and consume 7000-9800 calories a week. 7700 calories = 1 kg of fat and 0.91-1.27 kg less in a week.

As far as the human body's energy consumption is concerned, the human body's energy consumption is not just the physical exertion we can see every day. On the contrary, for those who engage in light physical activities, the proportion of physical exertion is not large. The energy consumption of adults mainly includes three aspects: basal metabolism, thermal effect of food and physical activity. Basal metabolism refers to the minimum energy consumed by the human body to maintain life and for the organs to perform the most basic physiological functions, such as maintaining body temperature, blood flow, respiratory movement, skeletal muscle tension and glandular activity. The energy consumed by basal metabolism is quite astonishing. Among those who do light manual labor, basal consumption accounts for about 70% of total energy consumption, food thermal effect consumption accounts for 10%, and physical activity consumes about 20%. The basic consumption can remain basically unchanged even when sleeping, so eating or not eating midnight snacks will not affect the basic consumption.

Secondly, the total daily energy intake is a general concept, and it is unscientific to highlight the harm of a single meal or snack. If you have consumed enough energy from three meals a day, then eating a midnight snack would definitely be excessive. Therefore, it is fine to control the total energy intake properly, even if it is divided into multiple meals, and having two midnight snacks will not pose much risk of weight gain.

The energy ratio of three normal meals a day is related to the energy consumption after each meal. For example, the most standard ratio of three meals is 30% for breakfast, 40% for lunch and 30% for dinner. The main factor to be considered is that lunch should not only make up for the insufficient energy consumption after breakfast, but also prepare for the work consumption in the afternoon. However, the living habits of modern people have changed greatly. Many people skip breakfast and eat lunch directly, and can work or entertain until midnight after dinner. Naturally, many people have the habit of eating midnight snacks.
