our body. For example, a lean, young adult male's body weight may
be approximately 62 percent water, 16 percent protein, 16 percent fat,
and less than 1 percent carbohydrate. Most of his remaining weight
(about 5 percent) would be attributed to minerals. We will spend a lot
more time talking about the finer details of body composition in later
chapters.
   Our body is mostly made of water, fats, protein, carbohydrate,
 minerals, DNA, and other special molecules.
