Definition
HIGHER
Term
20.   _____mass adds relatively little to the RMR.
Definition

Definition
LEAN BODY MASS THAT IS LOST
Term
26.   Why do obese individuals generally have higher RMR’s than non-obese people.

Definition
STRENUOUS EXERCISE
Term
39.   It is believed that _____ may help prevent age-related weight gain in sedentary individuals, and that the protective mechanism may be an altered RMR.
