fatty tissue is healthy to a certain point. anything past that point can contribute to many health challenges, including diabetes, hypertension, etc.
Body composition is more important than weight because two people can look like they are same size and weight but one can have more fat tissues than the other. In addition, muscle weighs more than fat so a body builder will weigh heavier than someone with same physical dimensions.
Body composition is the accurate representation of persons health because it's the most accurate as far as fatty tissue v muscle is concerned.
