Is Knowing Your BMI Important for Weight Loss?

August 1, 2021


How can I know if my weight is healthy?

There are several different ways to determine whether or not your weight is healthy. One of the most commonly used methods to determine if your weight is healthy is measuring your body mass index, which is more commonly known as BMI. BMI is used to measure body fat based on an adult person’s height and weight.


What is the calculation of BMI?

BMI is calculated by taking a person’s weight (in kilograms) divided by the square of their height (in meters). Since most Americans don’t use the metric system when weighing in (or just about anything else), you can still use the same formula using pounds and inches squared in the place of kilograms and meters. Once you have that number, then multiply the final number by 703.

Alternatively, you can avoid dealing with metric to U.S. customary measurement conversions entirely by simply using the BMI calculator provided by the Centers for Disease Control and Prevention.. 

All you need to do is insert your height (in feet and inches) and weight into the indicated boxes and click the Calculate button.

Once you’ve calculated your BMI, you’ll find yourself falling in one of these categories:

  • Less than 18.5: underweight range
  • 18.5 to 24.9: normal/healthy weight range
  • 25.0 to 29.9: overweight range
  • 30.0 and higher: obese range


My doctor says I’m at a healthy weight but according to my BMI, I’m overweight. Why is that?

Remember that the BMI is intended to measure body fat. It does not take factors like muscle into account. Muscle weighs more than fat, so people who have more muscle mass will weigh more on a BMI because it uses your weight and height in its calculation.

That’s why it’s important to remember that a BMI is not the only indicator or diagnostic measurement of what is considered a healthy or unhealthy weight.

Lifelong Metabolic Center’s weight loss program takes this information into account. We go beyond the BMI — we use body composition, DNA testing and other methods to determine the best way to help you lose weight more efficiently and effectively and keep the pounds off for good.


Is it important to know your BMI for weight loss?

It’s useful knowledge to have, but it’s not the only important piece of information available to you when it comes to weight loss. As discussed earlier, a BMI only estimates body fat and not muscle. Being able to determine what percentage of your body is muscle and what’s fat is equally important.

It also helps to have an understanding of your family’s medical history as well. Obesity can be caused in part by genetics and various other risk factors you may or may not be aware of.


Lifelong Metabolic Center goes beyond the BMI

While the BMI is one piece of information that is used at Lifelong Metabolic Center, we use others as well. We look at the percentage of your weight that is fat versus muscle versus water. We also include DNA testing as part of our weight maintenance program. This can give us some insight as to foods and amount of exercise may work best for you, and we’ll implement that body composition and genetic information into your individualized weight loss (and then) maintenance program to help you lose that unwanted weight for life!
