A member asked:

Which body fat percentage is generally considered severely underweight for an 18 year old male?

A doctor has provided 1 answer

You don't need any: Concepts about "ideal weight" are junk -- subscience and entertainment. Your best weight is whatever looks and feels right to you while you're able to take part successfully in your favorite sport. Photo guy isn't worried. A man needs no body fat whatever -- in fact, "ripped" muscle definition is much prized by both athletes and men just seeking to look good.
