Increasing your muscle mass will also increase your

Question

BlackTom AI · Accepted Answer

Muscle tissue is more metabolically active than fat, so increasing muscle mass raises your resting (basal) metabolic rate.

1) Relevant knowledge points and concepts
- Basal/resting metabolic rate (RMR) is the energy expended by the body at rest to maintain basic functions.  
- Different tissues consume different amounts of energy per unit mass; skeletal muscle uses more energy at rest than adipose (fat) tissue.  
- Changes in body composition (more muscle, less fat) therefore alter total daily energy expenditure.

2) Step-by-step reasoning
- Quantify typical resting energy use per kg: skeletal muscle ≈ 13 kcal/kg/day (commonly cited average), adipose tissue ≈ 4.5 kcal/kg/day.  
- If you gain muscle mass, each kilogram of added muscle burns more calories at rest than the same kilogram of fat would.

3) Calculations (intermediate steps shown)
- Difference per kg: 13 − 4.5 = 8.5 kcal/kg/day more than fat.  
- Example: gaining 5 kg of muscle (replacing fat or added to existing mass) would increase RMR by roughly 5 × 8.5 = 42.5 kcal/day (on the conservative differential basis).  
- If comparing absolute muscle contribution: 5 kg muscle × 13 kcal/kg/day = 65 kcal/day contributed by that muscle mass at rest.

4) Why the correct answer is correct
- Because muscle requires more energy to maintain even during rest, increasing muscle mass increases overall metabolic rate (higher RMR and often higher total daily energy expenditure with activity).

5) Why the other options are incorrect
- "Proportion of fat.": Increasing muscle typically lowers body fat percentage (proportion), not increases it.  
- "Risk of low-back pain.": Strengthening muscles, especially core and back muscles, tends to reduce—not increase—risk of low-back pain when done properly.  
- "Testosterone levels.": Building muscle does not inherently raise baseline testosterone levels; hormones influence muscle growth, but increased muscle mass does not reliably increase long-term testosterone.

6) Conclusion
- Therefore the correct answer is metabolic rate. This matches the provided answer: "metabolic rate."
