Macro Coach Certification Macro Coach Macronutrient Science Questions and Answers 2 — Questions and Answers
Question 1: Which macronutrient provides the most energy per gram?
- Carbohydrates
- Protein
- Fat (Correct answer)
- Fiber
Correct answer: Fat
Fat provides 9 kcal per gram, which is more than double the 4 kcal per gram provided by carbohydrates or protein.
Question 2: What is the primary role of dietary fat in hormone production?
- Fat provides glucose for hormone synthesis
- Dietary fat supplies cholesterol and fatty acids needed to synthesize steroid hormones (Correct answer)
- Fat is converted directly into insulin
- Fat stimulates growth hormone release from the pituitary
Correct answer: Dietary fat supplies cholesterol and fatty acids needed to synthesize steroid hormones
Steroid hormones such as testosterone and estrogen are synthesized from cholesterol and fatty acids derived from dietary fat.
Question 3: Which type of carbohydrate has the highest glycemic index?
- Oats
- White rice (Correct answer)
- Lentils
- Fructose
Correct answer: White rice
White rice has a very high glycemic index (around 70–80) because its starch is rapidly digested and absorbed into the bloodstream.
Question 4: In the context of macronutrient science, what does 'net carbs' refer to?
- Total carbohydrates minus protein
- Total carbohydrates minus fiber and sugar alcohols (Correct answer)
- Total carbohydrates minus fat
- Total carbohydrates minus vitamins
Correct answer: Total carbohydrates minus fiber and sugar alcohols
Net carbs are calculated by subtracting fiber and sugar alcohols from total carbohydrates because they have minimal impact on blood glucose.
Question 5: What is the nitrogen balance concept important for when coaching clients on protein intake?
- It measures hydration status
- It indicates whether a client is retaining or losing muscle mass based on protein intake vs. excretion (Correct answer)
- It tracks fat oxidation rates
- It calculates carbohydrate storage capacity
Correct answer: It indicates whether a client is retaining or losing muscle mass based on protein intake vs. excretion
A positive nitrogen balance indicates protein synthesis exceeds breakdown, signaling muscle growth, while negative balance suggests muscle loss.
Question 6: Which fatty acid classification describes fats with no double bonds in their carbon chain?
- Monounsaturated
- Polyunsaturated
- Saturated (Correct answer)
- Trans
Correct answer: Saturated
Saturated fatty acids have no double bonds between carbon atoms, making them solid at room temperature and more stable.
