BMI is further influenced by factors such as age, sex, ethnicity, muscle mass, and body fat, and activity level, among others. For example, an older person who is considered a healthy weight, but is completely inactive in their daily life may have significant amounts of excess body fat even though they are not heavy.
This would be considered unhealthy, while a younger person with higher muscle composition of the same BMI would be considered healthy. In athletes, particularly bodybuilders who would be considered overweight due to muscle being heavier than fat, it is entirely possible that they are actually at a healthy weight for their body composition.
Generally, according to the CDC:. The same factors that limit the efficacy of BMI for adults can also apply to children and adolescents. Additionally, height and level of sexual maturation can influence BMI and body fat among children. BMI is a better indicator of excess body fat for obese children than it is for overweight children, whose BMI could be a result of increased levels of either fat or fat-free mass all body components except for fat, which includes water, organs, muscle, etc.

Today, IBW is also used widely throughout sports, since many sports classify people based on their body weight. Note that IBW is not a perfect measurement. It does not consider the percentages of body fat and muscle in a person's body. This means that it is possible for highly fit, healthy athletes to be considered overweight based on their IBW. This is why IBW should be considered with the perspective that it is an imperfect measure and not necessarily indicative of health, or a weight that a person should necessarily strive toward; it is possible to be over or under your "IBW" and be perfectly healthy.
How much a person should weigh is not an exact science. It is highly dependent on each individual. Thus far, there is no measure, be it IBW, body mass index BMI , or any other that can definitively state how much a person should weigh to be healthy. They are only references, and it's more important to adhere to making healthy life choices such as regular exercise, eating a variety of unprocessed foods, getting enough sleep, etc.
That being said, many factors can affect the ideal weight; the major factors are listed below. Other factors include health conditions, fat distribution, progeny, etc. In theory, age shouldn't be a large determinant of an IBW past the ages of for girls and for boys, after which most people stop growing.
