Absolutely, BMI is an effective method to measure healthy body fat However, it comes with several limitations. It is essential to recognize that BMI is just a measure that does not include the body's composition. There are many different body types that differ in the distribution of fat and muscle mass. The best method to obtain reliable and precise results is to take different measurements instead of using this as the sole method.

For adults

The main problem that is a problem with using the BMI technique is the fact that it's an estimation of body mass rather than fats in the body. The main components that affect BMI include age and weight, height, and so on. There is a chance that someone has a healthy weight but is not physically active in the daily routine. It is clear that there's a strong likelihood that the person is carrying an excess amount of body fat that can make him unhealthy. Also, athletes are thought of as overweight if they possess muscles larger than fat, however it is possible that they're overweight as a result due to their physique. Also, it has been discovered that women carry more body fat than males. It is important to look up the list of countries based on weight index.

In the case of children

The reasons we've discussed to restrict the use for BMI for adults, as well as its effectiveness for children. We've found that weight and height are the most significant variables for body fat and BMI among young children. But, we can conclude that BMI is an more reliable indicator of body fat in obese children than for overweight ones.


BMI calculators aren't suitable for bodybuilders, athletes pregnant women, small children or any other. The primary reason behind this assertion is that BMI does not distinguish whether your weight will be carried in fat or muscle, because it is primarily based on numbers. For instance, athletes and muscles builders generally have an elevated BMI not because they're overweight, however they do have a higher muscles mass. There is no way to conclude on the basis of BMI results that they're at risk of risk of developing health problems in any way. In the same way, older or younger children may be losing muscles, which is why they may have a lower BMI however it can't be said that they are susceptible to developing illnesses. In addition, pregnant women typically encounter changes in body composition and therefore an adult BMI calculator will not work to be used in this scenario.
