While we are discussing the 13-year-old, you will see that they have different sizes and weights. 

Some may have gone through the whole process of puberty while others are still trying to understand the changes. These changes can also cause physical maturation which is common among teenagers these days. Your height and body makeup also matter. 

The tall kids can weigh more than the short ones. It is due to the bone structure that makes them weigh more. But, if the shorter one is obese, he or she can weigh more too. You must know that here your bones and muscles are an important factor contributing to your weight. Children with muscular strength and energy can also show a good physical appearance. So, these factors can change the way we see things. 

Here, genes also take an important part. You might be the same weight as your mom and dad or your grandparents. Sometimes, obesity or being lean is in your genes. No matter how much you eat, your weight remains the same. This is something that your body has and if you want to gain weight there are other ways. There are treatments or exercises or even supplements that help you with it.

You can tell them how they can accept these changes as it is normal to have them. They are going to be adults and the other kids go through the same situation. You can show them pictures of other kids who are in puberty and feel low. 

Tell them the brave stories of how other children can accept the increase or decrease in their body weight. It will help them to understand and bravely accept the changes.
