rate [RMR]). They’re different but not vary. The difference isn’t that

important right now. Just know that you’ll be using one or the other not both
when calculating your needs

3. Our body composition

Along with body weight, how much lean or fat-free mass (FFM) we
have will affect our energy needs.

• FFM such as muscle, bone, and connective tissue is
metabolically active and costly to maintain. (It also requires
