After puberty, boys enter a period of rapid growth. The rapid growth period usually occurs between the ages of 12 and 15. Development is relatively slow after that, but the growth cycle usually lasts until about 18 to 19 years old. In other words, parents should help boys supplement potassium, zinc, calcium, phosphorus, magnesium and other trace elements in a timely manner between the ages of 12 and 15, and pay attention to the balanced intake of protein, amino acids, vitamins and other nutrients.

Parents should urge their children to go to bed early and get up early, so that the child can produce more growth hormone during sleep, so that the child grows quickly. It is also recommended that children do more sports such as basketball and pull-ups, and less weight lifting and shot put, so that their bones and muscles have plenty of space to grow and stretch.

Children are in a period of rapid growth, parents should reasonably control the amount of food. Some relevant studies have proved that children who eat 70% or 80% of their fill are more likely to grow up than those who eat very full. This is mainly because people in the semi-starvation state growth hormone secretion faster. Meanwhile, according to the data, thin children are more likely to realize a sharp rise in body size than fat children. This is mainly due to the fact that when a large amount of nutrients are converted into fat, it is difficult for bones and muscles to have enough nutrients. Therefore, it is best for boys to maintain reasonable body proportions during the rapid growth period and not to miss the long golden weeks because they are too fat.
