First, good health.
A series of diseases will appear after obesity, such as hyperlipidemia, hypertension, hyperglycemia and so on. Many of these diseases need to be controlled by taking medicine, which is very harmful to children's health. Nowadays, these diseases are getting younger and younger, because many children always pay no attention to their healthy diet and daily life. If children can pay attention to these, they can avoid these situations and grow up healthier.
Second, psychological problems.
Some obese children will always be laughed at by others, and even have school violence, which is not conducive to children's mental health. A child may not be confident enough because of others' ridicule. Even if he loses weight in the future, these will become the shadow of his childhood and may even affect him for life.
Therefore, children should pay attention to their health from an early age, so as to grow up healthily and happily. Many parents are very careful when raising their children for fear that their children will be hungry. They always prepare three meals a day properly. Many children like fried food or cakes and other sweets very much, and their parents try their best to satisfy them. This is not right in itself. To let children control their bodies, they must start with diet and exercise.
