BMI (Body Mass Index) is one of the best methods to discover if you are overweight. However, the calculation is not complete. Perhaps the mirror may be a better method to determine if you are overweight.
According to the BMI chart the healthy range is between 18.5 and 24.9. Anything above 25 is considered overweight, and if you're over 30 you are morbidly obese. If the BMI calculator gives back a value of less than 18.5, you should immediately go to a doctor.
This is important!
BMI can not figure out what the difference is between muscle and fat. When you fitness a lot you will likely get a higher BMI. In short, the BMI calculation does not take into account your body type, bone density, your age and your overall health.
So people, take the BMI not too serious and do not start too fast with diet.
