Which macronutrient is the primary building block for muscle tissue?
Carbohydrates
Fats
Proteins
Vitamins
Proteins supply amino acids necessary for muscle repair and growth. They serve as the primary building blocks of body tissues.
Which macronutrient provides approximately 9 calories per gram?
Carbohydrates
Proteins
Fats
Vitamins
Fats provide about 9 calories per gram, which is more than carbohydrates or proteins. This higher energy density makes fats the most calorie-rich macronutrient.
Which of the following foods is primarily a carbohydrate source?
Baked potato
Chicken breast
Almonds
Salmon
Baked potatoes are rich in starch, making them a primary source of carbohydrates. Chicken breast and salmon are mainly proteins, while almonds are higher in fats.
Which macronutrient is most abundant in olive oil?
Carbohydrates
Proteins
Fats
Vitamins
Olive oil is composed almost entirely of fats, primarily monounsaturated fatty acids. It contains negligible amounts of proteins or carbohydrates.
Which macronutrient is the body's preferred source of quick energy?
Proteins
Carbohydrates
Fats
Minerals
Carbohydrates are broken down quickly into glucose, which is the body's main fuel for immediate energy needs. Fats and proteins take longer to metabolize.
A nutrition label shows per serving: Carbohydrates: 30g, Protein: 5g, Fat: 2g. Which macronutrient is present in the highest amount?
Protein
Carbohydrates
Fat
Vitamins
The label lists 30 grams of carbohydrates, which exceeds the 5 grams of protein and 2 grams of fat. Therefore, carbohydrates are present in the highest amount.
A 100g serving of almonds contains roughly 21g protein, 49g fat, and 22g carbohydrates. Which macronutrient contributes the most calories in this serving?
Protein
Carbohydrates
Fat
Vitamins
Fat provides 9 calories per gram, so 49g of fat yields 441 calories. That exceeds 84 calories from protein (21g × 4) and 88 from carbs (22g × 4).
Which of the following meal combinations provides a natural source of all three macronutrients?
Grilled chicken with brown rice and olive oil
Apple and celery
Skim milk only
Boiled egg whites
Grilled chicken provides protein, brown rice supplies carbohydrates, and olive oil adds healthy fats. The other options lack one or more macronutrients.
During high-intensity exercise, which macronutrient is primarily used for energy?
Fats
Carbohydrates
Proteins
Vitamins
High-intensity activity relies on quick energy from carbohydrates stored as glycogen. Fat oxidation is slower and proteins are a minor fuel source during intense bursts.
Which food has the highest protein-to-calorie ratio?
Greek yogurt
White rice
Olive oil
Spinach
Greek yogurt offers a high amount of protein per calorie compared to rice or oil. Spinach is low in calories but also lower in overall protein density.
If you consume 50g of carbohydrates, 20g of protein, and 10g of fat, how many total calories have you consumed?
370
400
460
250
Carbs and protein each provide 4 cal/g (50×4 + 20×4 = 280), and fat provides 9 cal/g (10×9 = 90). The total is 280 + 90 = 370 calories.
Which statement best describes dietary fiber?
A carbohydrate that is not fully digested
A type of protein
A form of fat
A vitamin
Dietary fiber is a non-digestible carbohydrate that passes through the digestive tract mostly intact. It helps regulate digestion and blood sugar levels.
Increasing intake of which macronutrient is the primary focus of a high-fat ketogenic diet?
Carbohydrates
Protein
Fats
Vitamins
A ketogenic diet dramatically increases fat intake while restricting carbohydrates. This shift moves the body into ketosis, relying on fat for energy.
Which macronutrient aids in hormone production and vitamin absorption?
Carbohydrates
Proteins
Fats
Minerals
Dietary fats are essential for synthesizing certain hormones and help absorb fat-soluble vitamins A, D, E, and K. Without adequate fats, these processes are impaired.
Which macronutrient yields 4 calories per gram and is essential for muscle repair?
Carbohydrates
Proteins
Fats
Vitamins
Proteins provide 4 calories per gram and supply amino acids needed for repairing and building muscle tissue. Carbohydrates also provide 4 cal/g but are not primarily used for repair.
A nutrition label lists per serving: 12g protein, 24g carbohydrates, and 8g fat. Approximately what percentage of the total calories comes from fat?
33%
44%
11%
22%
Fat provides 8g × 9 cal/g = 72 cal. Total calories are (12×4 + 24×4 + 72) = 216. The fat percentage is 72/216 ≈ 33%.
An endurance athlete follows a diet with 60% carbohydrates, 20% protein, and 20% fat. If they consume 3000 calories in a day, how many grams of carbohydrates do they eat?
450g
300g
600g
200g
60% of 3000 calories is 1800 calories from carbs. Dividing by 4 cal/g yields 450 grams of carbohydrates.
From a caloric density perspective, reducing which macronutrient intake would most efficiently lower total daily calories?
Carbohydrates
Proteins
Fats
Vitamins
Fats have the highest energy density at 9 calories per gram, so cutting fat reduces total calories more per gram than cutting carbs or protein, which are 4 cal/g.
Which of the following meal compositions best reflects a 600-calorie meal with 30% protein, 40% carbohydrates, and 30% fat?
45g protein, 60g carbohydrates, 20g fat
30g protein, 60g carbohydrates, 30g fat
50g protein, 40g carbohydrates, 20g fat
60g protein, 50g carbohydrates, 15g fat
180 cal from protein (45×4), 240 from carbs (60×4), and 180 from fat (20×9) total 600 calories with the desired 30/40/30 split.
During prolonged fasting, which macronutrient source does the body primarily break down to maintain blood glucose through gluconeogenesis?
Fats
Proteins
Carbohydrates
Vitamins
In extended fasting, the body converts amino acids from protein breakdown into glucose via gluconeogenesis. Fat stores are preserved longer for energy once glucose needs are met.

Cheat Sheet

  1. Understand the Three Macronutrients - Think of carbs, proteins, and fats as your body's power trio, each delivering energy in different amounts. Carbs and proteins supply 4 calories per gram, while fats pack a whopping 9 calories per gram, fueling everything from brainpower to workouts. Healthline
  2. Identify Common Food Sources - Become a macronutrient detective by spotting carbs in grains, fruits, and veggies, proteins in meats, beans, and dairy, and fats in oils, nuts, and avocados. Knowing where each nutrient hides helps you build balanced meals without the guesswork. Healthline
  3. Analyze Nutritional Labels - Nutritional labels are treasure maps to macronutrient gold! Learn to read serving sizes, then check grams of carbs, protein, and fat so you know exactly what you're fueling your body with. USDA
  4. Calculate Macronutrient Percentages - Turn calories into percentages by dividing calories from each nutrient by total calories. For example, 10 g of fat equals 90 calories - if your snack has 200 calories, that's 45% from fat! This math trick reveals which nutrients dominate your plate. Healthline
  5. Understand Recommended Intake Ranges - The USDA suggests adults aim for 45 - 65% of calories from carbs, 10 - 35% from protein, and 20 - 35% from fat. Keeping these ranges balanced helps you stay energized, support muscle growth, and maintain overall health. Healthline
  6. Recognize the Role of Fiber - Fiber is a special carb that can't be digested but fuels your gut bacteria, helps digestion run smoothly, and keeps blood sugar in check. Load up on whole grains, fruits, and veggies to meet your daily fiber quota. Be Beyond Hunger
  7. Differentiate Between Fat Types - Not all fats wear capes! Unsaturated fats from nuts, seeds, and fish are heart-healthy heroes, while saturated fats from red meat and full-fat dairy should be enjoyed in moderation. Learn the differences to make smarter swaps. Be Beyond Hunger
  8. Apply Macronutrient Knowledge to Meal Planning - Use your newfound macronutrient smarts to craft colorful, balanced plates that meet your energy needs and taste buds. Planning ahead ensures you hit your targets without stress or bland meals. Verywell Fit
  9. Interpret Macronutrient Roles in Energy Production - Carbs are your body's go-to energy source for quick fuel, proteins repair and build muscles, and fats store energy for the long haul. Balancing these keeps you powered up all day long. Healthline
  10. Be Aware of Label Discrepancies - Did you know actual macronutrient amounts can differ from what's printed on labels? Stay sharp by cross-referencing trusted studies and resources to make the most informed dietary choices. NCBI
