Question

BlackTom AI · Accepted Answer

RQ (respiratory quotient) is the ratio CO2 produced / O2 consumed and tells which substrates are being oxidized (carbohydrate RQ ≈ 1.0, fat RQ ≈ 0.7, protein ≈ 0.8). FQ (food quotient) is the RQ that corresponds to the macronutrient mix of the diet. The key principle: if FQ > RQ, dietary carbohydrate (high FQ) exceeds the carbohydrate being oxidized (lower RQ), so the surplus dietary carbohydrate must be stored—ultimately promoting fat synthesis. Conversely, if RQ > FQ the body is oxidizing relatively more carbohydrate than the diet supplies and is therefore mobilizing stored fat.

Step-by-step reasoning and calculations:
- Compute the difference (FQ − RQ) for each option. A positive difference indicates more carbohydrate in the diet than is being oxidized → likely fat storage.
  1) RQ = 0.84, FQ = 0.84 → FQ − RQ = 0.84 − 0.84 = 0.00 (no net fat storage)
  2) RQ = 0.90, FQ = 0.70 → FQ − RQ = 0.70 − 0.90 = −0.20 (negative → net fat mobilization)
  3) RQ = 0.90, FQ = 1.00 → FQ − RQ = 1.00 − 0.90 = +0.10 (positive → surplus dietary carbohydrate → fat gain)
  4) RQ = 1.00, FQ = 1.00 → FQ − RQ = 1.00 − 1.00 = 0.00 (balanced)

Why option 3 is correct: it is the only choice with a positive FQ − RQ (1.00 − 0.90 = +0.10), meaning the diet supplies more carbohydrate than the person is oxidizing, so excess carbohydrate will be converted to and stored as fat. Why the others are incorrect: option 1 and 4 have zero difference (no net fat gain or loss), and option 2 has a negative difference indicating net fat oxidation (mobilization), not gain.

Final confirmation: therefore the scenario most likely to lead to fat gain is RQ = 0.90 and FQ = 1.00, matching the provided answer.
