How to Measure and Interpret Body Mass Index

In my effort to change my body this year, I am thoroughly studying diet and weight loss topics. Body Mass Index is a topic that a person working on weight loss must understand. Here is what I have learned about body mass index.

What does body mass index (BMI) mean? According to the centers for disease control, the "Body Mass Index (BMI) is a number calculated from a person's weight and height. BMI provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems." In other words, by calculating how much you weigh in relation to how tall you are you getting a better idea of how fat you are. This will indicate your chance of developing weight related health problems.

How do I calculate my body max index (BMI)? To calculate your body mass index (BMI), you need to divide your weight in lbs by your height in inches squared. Then multiply this number by 703. The equation looks like this: Weight / inches tall ½ X 703. Therefore, if you weigh 220 pounds and are 64 inches tall, your calculation would be 220 / 64½ X 703, making your BMI are 37.76.

What is an acceptable body max index (BMI)? For an adult age 20 or older, a BMI is 18.5 is underweight, a normal BMI is 18.5-24.9, a BMI of 25-29.9 is overweight and a BMI of 30 or more is obese. Therefore, the person who is 220 pounds and 64 inches tall, or 5'4" would be considered obese.

Is body mass index (BMI) different for adults than for kids and teens? For children and teens, body mass index (BMI) is also calculated by weight and height. While the technique for calculating body mass index is the same as in adults, the results are measured differently in that it is measured in relation to where other children of the same age are. The reason body mass index (BMI) is measured differently in children is that children change so drastically so often, that looser standards are required. Here is a chart that measures obesity for children and teens according to Body Mass Index.
