Do you know, it has been said that the body mass index is really accurate in judging obesity?
No, the calculation formula of body mass index value: body mass index = weight (kg)/ height 2 (m2), so it has nothing to do with fat content, but it is only related to weight, but it doesn't mean that the smaller your weight, the less fat you have. Some people look thin, but in fact there is a lot of fat, because fat will be hidden in blood vessels and can't be seen.
