1How many kilocalories per gram does dietary fat provide?
A.4 kcal/g
B.7 kcal/g
C.2 kcal/g
D.9 kcal/g
Explanation: Fat is the most energy-dense macronutrient at 9 kcal per gram, more than double carbohydrate or protein. This density is why high-fat foods contribute large amounts of energy in small portions.
2Carbohydrate and protein each provide how many kilocalories per gram?
A.9 kcal/g
B.7 kcal/g
C.4 kcal/g
D.5 kcal/g
Explanation: Both carbohydrate and protein yield approximately 4 kcal per gram. Knowing the Atwater factors (carb 4, protein 4, fat 9, alcohol 7) lets a coach estimate energy intake from food labels.
3Alcohol provides approximately how many kilocalories per gram?
A.7 kcal/g
B.4 kcal/g
C.9 kcal/g
D.0 kcal/g
Explanation: Alcohol contributes about 7 kcal per gram, second only to fat in energy density. These are largely 'empty' calories with little nutrient value, which a coach should factor into a client's energy budget.
4What is the Acceptable Macronutrient Distribution Range (AMDR) for carbohydrate in adults?
A.45–65% of total energy
B.20–35% of total energy
C.10–35% of total energy
D.65–80% of total energy
Explanation: The AMDR for carbohydrate is 45–65% of total daily energy. Carbohydrate is the body's primary and preferred fuel, especially for the brain and high-intensity exercise.
5What is the Acceptable Macronutrient Distribution Range (AMDR) for fat in adults?
A.10–20% of total energy
B.35–50% of total energy
C.45–65% of total energy
D.20–35% of total energy
Explanation: The fat AMDR is 20–35% of total daily energy. Adequate fat supports absorption of fat-soluble vitamins, hormone production, and essential fatty acid needs.
6What is the Acceptable Macronutrient Distribution Range (AMDR) for protein in adults?
A.5–10% of total energy
B.45–65% of total energy
C.20–35% of total energy
D.10–35% of total energy
Explanation: The protein AMDR is 10–35% of total daily energy. Protein supports tissue repair, enzyme and hormone synthesis, and satiety, and intake within this range is appropriate for most clients.
7Which organelle is primarily responsible for ATP production in the cell?
A.Ribosome
B.Lysosome
C.Golgi apparatus
D.Mitochondrion
Explanation: The mitochondrion is the site of aerobic energy production, generating most cellular ATP through oxidative phosphorylation. This is why it is often called the cell's powerhouse.
8In which organ does the majority of nutrient absorption occur?
A.Stomach
B.Small intestine
C.Large intestine
D.Esophagus
Explanation: The small intestine, with its villi and microvilli, provides the enormous surface area where most carbohydrate, protein, fat, vitamins, and minerals are absorbed into the bloodstream and lymph.
9Which enzyme found in saliva begins the chemical digestion of carbohydrates?
A.Pepsin
B.Salivary amylase
C.Lipase
D.Trypsin
Explanation: Salivary amylase (ptyalin) starts breaking starch into maltose in the mouth. Carbohydrate digestion then largely pauses in the acidic stomach and resumes in the small intestine with pancreatic amylase.
10Which organ produces bile to emulsify dietary fats?
A.Pancreas
B.Spleen
C.Liver
D.Gallbladder
Explanation: The liver produces bile, which emulsifies large fat droplets into smaller ones to increase the surface area for lipase action. The gallbladder stores and concentrates bile but does not produce it.

ISSA Nutritionist Study Tips from Top Performers

1Prioritize nutrition science — it is about half the curriculum (digestion, metabolism, energy balance, the macronutrients, vitamins, minerals, and hydration)
2Memorize the Atwater energy values (carbohydrate 4, protein 4, fat 9, alcohol 7 kcal/g) and the AMDRs (carb 45-65%, protein 10-35%, fat 20-35%)
3Master scope-of-practice boundaries — many questions test when to refer to a physician or registered dietitian versus what a coach may do
4Learn behavior-change frameworks: the Stages of Change model, motivational interviewing, and SMART goal setting
5Even though the exam is open-book, practice the 100-question bank and review every miss with the AI tutor so you can apply concepts quickly
