What Are the Controlling Factors of An 11-Year-Old Teens’ Average Weight?
In reality, determining the actual average weight of an 11-year-old teenager is more challenging. This is due to the fact that there are numerous factors that can influence the body weight of younger teenagers. They are as follows:
Genetics
The genes that your teenagers inherit from you can be a huge element affecting their body composition and shape, in addition to diet and activity levels. In other words, fat distributions or body compositions will vary for those who are from different genetic backgrounds. So, your kids can be completely a little bit heavier or more lightweight than the average recommended range.
Growth speed
Puberty occurs in almost all children between the ages of 8 and 14. When compared with the rest of the 13-year-old youngsters from the same room, you will see a wide range of body proportions and mass. Some youngsters have reached the end of puberty, while others are just beginning to go through the many stages of physical maturity.
Height

Other important parameters include bone density and muscle mass. Additionally, you should notice that there is a broad range of differences in body structure.
It is commonly known that muscle weighs more than fat. So, a child who is slimmer or stores more fat rather than muscle tissue is more likely to weigh less than a child who is muscular.
Location
Some parents might not believe this, but the region where your children live might also be a factor influencing their height, body weight and size. This can be associated with a number of things, like cultural practices, heredity, the onset of puberty, access to food, etc. All of these aspects can be altered based on the geographic location from anywhere on the planet.
