Question at position 2 Claudio has more lean body mass than Vanessa, so you could predict that Claudio has a resting metabolism that is ____ than Vanessa: the samelowerhighernot enough information

BlackTom AI · Accepted Answer

Resting metabolic rate (RMR) is strongly determined by lean body mass (LBM): muscle and other lean tissues are metabolically active and consume more energy at rest than adipose (fat) tissue. Therefore, with greater LBM, Claudio will have a higher resting metabolism than Vanessa.

1) Relevant concepts
- Lean body mass (LBM) = muscle, organs, bone—these tissues have higher basal energy needs.
- Resting metabolic rate (RMR) correlates positively with LBM; other factors (age, sex, hormones) also influence RMR but LBM is a primary determinant.

2) Step-by-step reasoning
- The question gives that Claudio has more LBM than Vanessa.
- Since RMR increases with LBM, if all else is equal, Claudio’s RMR must be greater.
- No additional information is needed to compare direction (higher vs. lower/same).

3) Illustrative calculation (all intermediate steps)
- Represent RMR as proportional to LBM: RMR = c × LBM (c = average kcal per kg lean mass).
- Example: let c = 22 kcal/kg/day, Claudio LBM = 60 kg, Vanessa LBM = 50 kg.
- Claudio RMR = 22 × 60 = 1320 kcal/day.
- Vanessa RMR = 22 × 50 = 1100 kcal/day.
- Difference = 1320 − 1100 = 220 kcal/day → Claudio’s RMR is higher.

4) Why the correct answer is correct
- Because lean tissue requires more energy at rest than fat tissue, having more lean mass raises baseline energy expenditure; therefore Claudio’s resting metabolism is higher.

5) Why other options are incorrect
- "The same": would only be true if both had equal LBM and other factors identical.
- "Lower": contradicts the known relationship between LBM and RMR.
- "Not enough information": unnecessary here because the LBM difference alone is sufficient to predict the direction of difference in resting metabolism.

6) Conclusion
Claudio’s resting metabolism is higher, which matches the provided correct answer: higher.
