NOTE BMI should not be used as a guideline for health risks for the following groups:
GROUP | REASON |
|
|
Children and teenagers | BMI ranges are only based |
| on adult heights. |
|
|
Athletes and body builders | BMI does not differentiate |
| between fat and muscle, |
| thus making it inaccurate |
| for persons with high |
| muscle volumes. |
Pregnant or nursing | This group generates |
women | naturally high fat reserves |
| as part of the pregnancy. |
|
|
People over the age of 65 | Fat reserves naturally tend |
| to be higher with older |
| persons. |
|
|
NOTE The above BMI information is based on average Caucasian physique.
