The human body consumes energy to maintain the heartbeat, blood pressure, circulation, breathing, body temperature and the normal operation of every cell in the body. This process of energy consumption is called "basal metabolism". Metabolism determines the proportion of calories consumed by the body. The faster the metabolism, the faster the body consumes calories. On the contrary, the metabolism is slow, so a large part of the heat will be converted into fat and stored in the body. How much energy is consumed by basal metabolism every day or hour is expressed by basal metabolic rate. High basal metabolic rate means that the body consumes more energy in a calm state.

According to statistics, the metabolic rate of infants is about twice that of the elderly. Teenagers can increase their metabolic rate 15% ~ 20% because they contain growth hormone during their growth period, so they will not get fat if they eat too much. But after the age of 25, the metabolic rate will gradually decrease, and the body will consume less calories. Even if you eat as much as before, you may have excess energy.

In contrast, androgen can speed up metabolism, so young men are less likely to gain weight than women, while women over 30 are prone to physical deformation due to metabolism. Its speed will slow down with the increase of age, with an average decline of 2% every 10 year. If you eat as much at the age of 30 as you did at the age of 30, but your activity doesn't increase, then thin people at the age of 20 will easily become fat at the age of 30.

How to improve metabolism

Reduce the fat in the diet: If two foods with the same calories, one is rich in fat and the other is mainly composed of protein and carbohydrates, which food is more likely to make people fat? The answer is obviously the former, mainly because fat slows down metabolism. Therefore, a good way to lose weight is to eat more foods rich in protein and carbohydrates, which can speed up the metabolism of the human body, otherwise eating too much fat is easy to get fat.

Choice of carbohydrates: It should be noted that not all carbohydrates can consume calories, so how to choose carbohydrates? Polysaccharide food is the best choice. For example, vegetables, fruits and whole grain bread are all polysaccharide foods, such as starch and sugar. After eating these foods, only 4% energy will be wasted.

The method of slimming by improving metabolism is based on physical health. Needless to say, the effect is also very helpful to physical health.
