You're not a number: The BMI was never intended for use by individuals. If you feel well, are athletic, & keep up with peers at fitness activities, you have no reason to change. Elite track athletes have BMI's like yours. And don't try to gain by eating to gain fat -- a man needs no body fat and a woman needs only a little. Exercise regularly, handle any health issues with your physician's help & weight self-solves.

Question is why.: This information doesn't make me want to just recommend you gain weight. It makes me want to know why someone of your age is underweight. Is this new, or have you always been underweight? I would want some investigations - blood testing, colonoscopy, PSA/mammogram (don't know your gender).

You decide: Bmi was never intended to be a predictor for individual health outside of common sense. If you are a man, you do not need any body fat; a woman needs only a small amount. Most people want and benefit from some muscle. Many elite runners are "underweight", many zero-body-fat linebackers are "obese". You're a person, not a number. Get into fitness and your body will take care of itself.
