As stated, BMI compares your weight foryour height. In general, as BMI increases, so does the risk for healthcomplications. As you read, keep in mind that BMI is meant tocompare the average body type [1].You want to have a BMI less than 25 in order to decrease your risk for diseases associated with being overweight. A BMI between 18.5 and 24.9 corresponds to a healthy weight.As your weight rises above that level so does your risk for healthcomplications, including high blood pressure, Type 2 diabetes, heartdisease, stroke, osteoarthritis, and some cancers. You can find a BMI calculator on theNational Institutes of Health’s website at http://www.nih.gov. However, if you would like to learn how to calculate your BMI yourself, the equation is weight in kilograms (kg) divided by height in meters (m) squared.BMI Equation: Weight (kg) / Height (m) squaredHere's a sample calculation for a person who is 150 pounds and 5 feet 8 inches (68 inches) tall. Try this one for practice and then plug in your measurements in order to calculate your own BMI.1. Determine weight in kilograms.        Divide pounds by 2.2.           Ex). 150/2.2 = 68.2 kg2. Determine height in meters squared.        First, determine ht. in cm.            Ex). 68 inches x 2.54 = 172.72 cm.        Next, divide ht. in cm. by 100 to get ht. in meters.            Ex). 172.72/100 = 1.73        Then, square ht. in meters.             Ex). 1.73 x 1.73 = 2.98 3. Divide wt. in kg (68.2) by ht. in meters squared (2.98) = 23 BMI Categories                                         Less than 18.5 = Underweight18.5-24.9 = Healthy Weight25-29.9 = Overweight30-39.9 = Obese40 and above = Morbidly ObeseThe person in the sample calculation has a BMI of 23, which is within the healthy range (18.5-24.9). How about you?  [1] One of the BMI’s downfalls is that it does nottake into consideration your body composition, which means that if youhappen to be quite muscular, then your BMI may seem falsely high. TheBMI assumes that any extra weight you have is fat, not muscle.
