The problem with this index is that there are many people whose weight is relatively higher but their fat percentage is low, and the higher weight is muscle mass. In athletes who build muscles in the gym it is particularly noticeable, but among other people who do sports.
The new study published this month in the American Monthly for Clinical Nutrition wanted to check whether it is possible to divide the BMI into categories according to fat percentage. In the study, they checked the percentage of fat and the percentage of muscles in over 2.5 million people and reached the very expected result.
People with a low fat percentage – are at low risk of diseases and it doesn’t matter what BMI category they are in, except for the low BMI below 19, then there was no connection to the muscle percentage and the risk of diseases was low anyway.
The results of the study highlight the need to upgrade this index that is used so much (BMI) and to check the fat percentage at the same time as the calculation – because the fat percentage has a higher meaning than the weight.
