What is Body Mass Index?

Body Mass Index (BMI) is calculated using a person’s weight and height. Once the BMI value is calculated it can categorized to different ranges based on the value. The categories that BMI will measure include underweight, normal weight, overweight, or obese.

Once your BMI has been calculated, you can use the BMI value categories below to understand what range you fall in:

  • Normal Weight: If the value falls within 18.5 - 24.9, it means that your weight is generally healthy for your height.
  • Under Weight: A value below 18.5 indicates that you may be underweight, and it's advisable to consult a healthcare professional for guidance and potentially make some lifestyle changes.
  • Overweight: A value between 25 and 29.9 generally means that you may be overweight. It is recommended to consider lifestyle changes to achieve a healthier weight and speak with a healthcare professional.
  • Obese: A value of 30 or greater indicates obesity, and you should seek guidance from a healthcare professional to find a solution for weight management that works for you.

BMI Limitations

Though BMI is a useful tool for assessing general health it has its limitations. BMI is just a single indicator of health and will not always provide the full picture for an individual's health. When doing a full assessment of your health you should focus on other factors as well such as muscle mass, bone density, or body composition.
