BMI is a estimate for the amount of fat in your body. It tells you whether you need to lose weight or gain weight. Not all adults who have a Body Mass Index in the range labeled “normal” have healthy weight and muscles. They may have lots of fat but very little muscles. Similarly, if you are an athlete or a bodybuilder, then you may have lots of muscle and less fat and if your BMI is more than the normal range, then it may still be healthy.
