- 4 kcal
- 7 kcal
- 9 kcal (Correct answer)
- 11 kcal
Correct answer: 9 kcal
Fat provides 9 kcal per gram, making it the most energy-dense macronutrient.
Question 2: What is the Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates as a percentage of total daily calories?
- 10–30%
- 20–35%
- 45–65% (Correct answer)
- 55–75%
Correct answer: 45–65%
The AMDR for carbohydrates is 45–65% of total daily caloric intake according to the Dietary Reference Intakes.
Question 3: Which type of dietary fiber has been shown to help reduce LDL cholesterol levels?
- Insoluble fiber
- Soluble fiber (Correct answer)
- Resistant starch
- Cellulose
Correct answer: Soluble fiber
Soluble fiber forms a gel-like substance in the gut that binds to bile acids and helps lower LDL cholesterol.
Question 4: What is the thermic effect of food (TEF)?
- The caloric content of food after cooking
- The energy required to digest, absorb, and metabolize nutrients (Correct answer)
- The heat produced by the body during exercise
- The rate at which food raises core body temperature
Correct answer: The energy required to digest, absorb, and metabolize nutrients
TEF is the energy expended by the body to digest, absorb, and metabolize food, accounting for roughly 10% of total daily energy expenditure.
Question 5: According to the ACE Integrated Fitness Training Model, which professional is qualified to provide individualized medical nutrition therapy?
- ACE-certified Personal Trainer
- Registered Dietitian Nutritionist (RDN) (Correct answer)
- NSCA-certified Strength Coach
- Sports medicine physician only
Correct answer: Registered Dietitian Nutritionist (RDN)
Medical nutrition therapy requires licensure as a Registered Dietitian Nutritionist; personal trainers operate within general nutrition guidelines only.
Question 6: Which macronutrient is the predominant fuel source during high-intensity anaerobic exercise?
- Fat
- Protein
- Carbohydrate (Correct answer)
- Alcohol
Correct answer: Carbohydrate
Carbohydrates (stored as muscle glycogen) are the primary fuel for high-intensity anaerobic exercise because they can be broken down rapidly via glycolysis.
Question 7: What is the general recommendation for daily protein intake for a recreationally active adult, per kilogram of body weight?
- 0.4–0.6 g/kg
- 0.8–1.0 g/kg (Correct answer)
- 1.4–1.7 g/kg
- 2.5–3.0 g/kg
Correct answer: 0.8–1.0 g/kg
The RDA for protein is 0.8 g/kg/day for sedentary adults; recreationally active individuals fall in the 0.8–1.0 g/kg range, slightly higher than sedentary requirements.
