What is Body Mass Index (BMI)? | CalFit Sacramento, CA

Body Mass Index (BMI) is a fitness calculation that takes your height and weight to measure your body’s percentage of fat. It is used to determine whether or not your fat to muscle ratio is in a healthy range. As our bodies are designed to have a healthy amount of fat, it is wise to understand what a healthy amount looks like. Although a low BMI is considered healthier, too low of a ratio is actually considered unhealthy.

Here are some guidelines:

BMI below 19 = underweight
BMI between 19-25 = healthy weight
BMI between 25-30 = overweight
BMI above 30 = obese

When using a BMI calculator, there are some factors to consider. First, although BMI is a good indicator of healthy vs. unhealthy body fat percentage, it is not 100% accurate. It is used to help guide you towards a healthy fitness routine and nutritious diet. Second, once you have assessed your weight and BMI, it’s a good idea to talk to a Certified Personal Trainer who can help you map out a healthy exercise routine to help you reach your goals. Lastly, a typical BMI calculator is rarely used for children as their health requirements greatly differ from adults. Consult your child’s doctor if you are concerned about your child’s weight.
