If you are about 15 years old, the CDC says you are of healthy weight:

But that doesn't really mean anything in particular because some people are born to be chubby, others are born to be very skinny. What really matters is physical fitness, proper diet, and healthy lifestyle. You can be of healthy weight but if you lead a very sedentary (as in play xbox all day) lifestyle that results in underdeveloped muscles, lung capacity, stamina, etc it is still not healthy even if the generic BMI says you are.

Personally my BMI (for age 28) says I'm too skinny (its a 17.4) but my doctors says I'm perfectly fine because i eat right, sleep right, exercise daily, and instead of fat I've got quite a bit of muscle. Most of my family (genetic background) apparently is the skinny type of body, we're not meant to be chubby/fat.
