What is BMI?

BMI stands for Body Mass Index, and it is a way to compare your height vs weight. It is a controversial statistical tool because it does not take muscle mass, percentage of fat, mass of bones and physical built of a person into consideration.

But I would still say that BMI is accurate for most people who are not body builders or did strength training before. Accurate BMI can be determined using many online calculators. But you have to know how to analyze your BMI number.

Here is a guideline to determine the proper BMI

Underweight = Less than or equal to 18.5
Normal weight = Between 18.6-24.9
Overweight = 25-29.9
Obesity = BMI of 30 or greater

Remember that your BMI is only accurate if you don't have a muscular built.
