BMI is more likely to provide an accurate result if you are a typical target (not a child, pregnant, or having a high muscle mass). So, is a BMI of 21 good? You can use this post from Liftyolife ( to determine your BMI range.

1. What is a BMI of 21?

A BMI of 21 indicates that you have a body mass index of 21. A person’s weight and height are used to calculate their BMI, which tells you whether or not they are at a healthy weight. When calculating BMI, the weight of an adult is divided by their height squared.

2. Is a BMI of 21 good?

Is a BMI of 21 good? Yes, 100% that BMI of 21 is an ideal range according to the measurement of the World Health Organization and the Center for Disease Control and Prevention (CDC). 

The BMI range is described in detail below. If you have:

  • BMI < 18.50 – You’re in the underweight range.
  • 18.5 =< BMI < 25.00 – You’re in the healthy weight range.
  • 25 =< BMI < 30 – You’re in the overweight range.
  • 30 =< BMI – You’re in the obese range.

Based on all the above BMI ranges, a BMI of 21 is considered healthy.

Notes on calculating BMI:

  • Given that muscle weighs more than fat, extremely muscular people, such as heavyweight boxers, weight trainers, and athletes, may be considered obese despite their healthy weight.
  • Your ethnicity may also influence how likely you are to develop certain health conditions. Pregnant women and those over 60 should avoid using the BMI as a weight-loss tool.

Is a BMI of 21 good? Yes, it is good. When calculating a person’s BMI, it does not take into account factors such as age, gender, race, or muscle mass. But doctors can use this information to track the weight of populations and identify potential health issues in individuals.
