Body Mass Index is a simple and effective tool to determine whether or not your weight is a healthy one. For those who doubt the accuracy of this tool, please read this article.
There are very few people that have enough lean muscle mass to “fool” the calculator – like bodybuilders. There are also those that hold on to the “big-boned” theory. Note that the skeleton only accounts for about 15% of body mass. While there is some variation among different body types, the difference is fairly negligible. In fact, the BMI score actually under-classifies a fairly large percentage when compared to DEXA scans.
A BMI of around 23 is a good goal to strive for. Once a BMI of less than 25 is obtained, the abdominal muscles are revealed.
