A class member confides that she has gained 4 lbs since Thanksgiving. Is it time for alarm? In general, any gain in weight that can be attributed to an increase in lean body mass is a good weight gain. Which of the following structures is LEAST likely to be a component of lean body tissue?
  1. Bone
  2. Blood
  3. Muscle
  4. Essential fat
Explanation
Answer: D - Bones, muscles, nervous tissue, skin, blood and organs are all component parts of “lean” body tissue; fat is not. The chief function of body fat - whether essential fat or storage fat - is to serve as a reserve of energy for future use.
