Body Mass Index Chart Directly Proportional to Weight.

Body mass index chart is easy to understand. If your BMI is below 20: This indicates a lean BMI, which means you have a low amount of body fat. If you are an athlete, this can be desirable.

If you are not an athlete, a lean BMI chart can indicate that your weight may be too low which may lower your immunity.

If your body mass and body weight are low, you should consider gaining weight through good diet and exercise habits, to increase your muscle mass.

If you become pregnant this body mass index chart may help you.

You may want to know how much weight should you gain during your pregnancy?

It depends on how much you weighed before you conceived and how appropriate that weight is for your height. The relationship between your height and weight is expressed in a number called a "body mass index," or BMI.

  • If you were underweight for your height at conception (a BMI below 18.5), you should gain 28 to 40 pounds.
  • If you were overweight for your height (a BMI of 25 to 29.9), you should gain 15 to 25 pounds.

One variable body mass index chart fails to consider is lean body mass. It is possible for a healthy, muscular individual with very low body fat to be classified obese using the body mass index chart formula.
