By the end of this post, you’ll have a good understanding of BMI and whether or not it’s a good measure for you.

So, let’s get started! We’ll start with the basics.

What Is The BMI And What Does BMI Stand For?

BMI stands for Body Mass Index. BMI is a measure of body fat based on height and weight. It’s an easy way to assess whether you’re at a healthy weight or not. BMI is used for both men and women.

You can calculate your BMI with the calculator or charts we’ll provide in this post. Generally, if your BMI score is between 18.5 and 24.9, you’re considered to be at a healthy weight. If your BMI is between 25 and 29.9, you’re considered to be overweight, and lastly, if your BMI is over 30, you’re considered obese.

However, keep in mind that BMI doesn’t differentiate between muscle weight and weight that comes from fat.

Why Is BMI A Useful Tool?

BMI is useful in screening for bodyweight problems. You can determine if you’re at an unhealthy or healthy weight and whether changes to diet and exercise may be necessary.

Limitations Of BMI

Although BMI is a good tool for screening, it does have its limitations.

For example, muscular people – such as athletes and bodybuilders, tend to have a high BMI because of their increased muscle mass, even if they are very lean and don’t have a lot of body fat. That is because the body mass index overestimates the amount of body fat.

On the other hand, older adults and those who’ve lost muscle mass – such as the elderly, tend to have a low BMI because of the decrease in muscle mass and therefore body weight. However, that doesn’t mean they are unhealthy or underweight. This is because the body mass index underestimates the amount of body fat.

BMI is calculated the same way for people of all ages.

BMI Formula

The BMI Formula for adults is pretty simple. It’s the weight divided by the height in meters, squared.

The resulting number is called the BMI score, BMI value, or just BMI.

What Is My BMI?

Follow these steps to calculate your BMI with the BMI calculator:

  1. Choose units – metrics for centimeter and kilogram or standard for feet and pound.
  2. Add your height and weight according to the chosen unit.
  3. Get your calculated BMI value.
  4. Interpret the BMI score by the given BMI classifications. For more information about Body Mass Index keep reading after the BMI calculation!

Calculating BMI is a good starting point for understanding your ideal weight, but it’s not always accurate.

Here are some things to keep in mind when looking at your BMI result:

  • Your BMI may not be accurate if you have a lot of muscle mass.
  • Older adults often store more fat than younger adults.
  • Athletes may weigh more due to high muscle mass and get an overweight result.

Your BMI is a number that’s used to estimate how much you should weigh – it’s not the final answer.

Nevertheless, your BMI value is a good way to check in on your weight. For most people, a BMI in the 19-25 range is a good weight goal.

Just keep in mind that this isn’t a perfect way to measure if you’re at a healthy weight.

Trust your intuition and feelings about how you look and feel, and let that guide you when assessing your weight.

BMI Chart – What Is A Normal BMI?

If you are asking yourself, what the range of a healthy BMI is, here ere are the BMI categories or the BMI table, ranging from low to normal and high:

  • <19: underweight
  • 19 to 24: normal
  • 25 to 29: overweight
  • 30 to 39: obese
  • 40 or above: extreme obesity

A BMI chart is shown below. Follow the instructions to interpret it correctly!

  1. On the left side, find your height in inches.
  2. Look for your weight across the row in pounds.
  3. Find your BMI score on top of the column.

Body Mass Index And Health

Are you curious about your Body Mass Index (BMI) and how it relates to your health?

Here are some facts about BMI and health:

  • High BMI numbers, as well as low BMI scores, are related to greater risks of developing serious health conditions.

However, there is science pointing out that body fat, not necessarily BMI, is more associated with more serious health issues.

  • If you take in more calories than you burn, you will gain weight over time.
  • Being overweight or obese increases your risk of developing diabetes, heart disease, and stroke.
  • If you burn more calories than you take in, your body will lose weight over time.

Increasing your physical activity and eating healthy are the best ways to maintain a healthy weight, or reduce weight healthily.

Reducing body fat and aiming for a healthy weight is just easier possible by including regular exercise. For example, two to three times a week. Start small and then keep going.
