The NESTA Certified Sports Nutrition Specialist exam consists of 100 multiple-choice questions taken online and non-proctored, with roughly a 2-hour window, a 70% passing score, and 3 included attempts. It is open enrollment with no prerequisites. The credential covers performance nutrition science and physiology, carbohydrate/protein/fat needs and nutrient timing, micronutrients and oxidative stress, hydration and electrolytes, recovery and competition eating, evidence-based supplements, special cases (plant-based and environmental), and coaching application. This free practice bank provides 100 research-based selected-response questions with teaching explanations.

Sample NESTA Sports Nutrition Specialist Practice Questions

Try these sample questions to test your NESTA Sports Nutrition Specialist exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1How many kilocalories per gram does each gram of dietary carbohydrate provide?
A.4 kcal/g
B.7 kcal/g
C.9 kcal/g
D.2 kcal/g
Explanation: Carbohydrate and protein each yield approximately 4 kcal/g, while fat yields 9 kcal/g and alcohol 7 kcal/g. These Atwater factors are foundational for estimating an athlete's energy intake from food labels and diet records.
2Which energy system predominates during a maximal effort lasting roughly 10 seconds, such as a short sprint or single heavy lift?
A.Oxidative phosphorylation
B.ATP-PCr (phosphagen) system
C.Beta-oxidation of fatty acids
D.Krebs cycle alone
Explanation: The ATP-phosphocreatine (phosphagen) system supplies energy almost instantly for very short, maximal efforts of about 0-10 seconds. It does not require oxygen and relies on stored ATP and creatine phosphate.
3Glycogen is the primary storage form of which macronutrient in muscle and liver?
A.Protein
B.Fat
C.Carbohydrate
D.Cholesterol
Explanation: Glycogen is a branched polymer of glucose stored mainly in skeletal muscle and the liver. Muscle glycogen fuels working muscle, while liver glycogen helps maintain blood glucose.
4During prolonged moderate-intensity endurance exercise, what generally happens to the relative contribution of fat versus carbohydrate as exercise intensity increases toward maximal?
A.Fat contribution rises and carbohydrate contribution falls
B.Both fall equally
C.Neither changes with intensity
D.Carbohydrate contribution rises and fat contribution falls
Explanation: As exercise intensity increases, the body shifts toward carbohydrate as the dominant fuel because it can be metabolized faster per unit oxygen. Fat oxidation is highest at low-to-moderate intensities and declines at higher intensities (the crossover concept).
5Which term describes the energy expended to digest, absorb, and metabolize the food a person eats?
A.Thermic effect of food (TEF)
B.Resting metabolic rate (RMR)
C.Excess post-exercise oxygen consumption (EPOC)
D.Non-exercise activity thermogenesis (NEAT)
Explanation: The thermic effect of food (TEF), also called diet-induced thermogenesis, is the energy cost of processing nutrients and typically accounts for roughly 10% of total daily energy expenditure. Protein has the highest TEF of the macronutrients.
6Which macronutrient has the highest thermic effect of food, meaning the greatest percentage of its energy is used during digestion and metabolism?
A.Carbohydrate
B.Protein
C.Fat
D.Alcohol
Explanation: Protein has the highest thermic effect of food, with roughly 20-30% of its energy expended during digestion, absorption, and metabolism. Carbohydrate is intermediate (about 5-10%) and fat is lowest (about 0-3%).
7What is the primary monosaccharide that working muscle and the brain use directly for energy?
A.Sucrose
B.Lactose
C.Glucose
D.Maltose
Explanation: Glucose is the primary monosaccharide circulating in blood and used directly by muscle and brain for energy. Sucrose, lactose, and maltose are disaccharides that must first be broken down into monosaccharides.
8Gluconeogenesis refers to which metabolic process?
A.Breakdown of glycogen into glucose
B.Conversion of glucose into fatty acids
C.Oxidation of glucose to carbon dioxide and water
D.Synthesis of glucose from non-carbohydrate sources such as amino acids and glycerol
Explanation: Gluconeogenesis is the synthesis of new glucose from non-carbohydrate precursors such as glucogenic amino acids, lactate, and glycerol. It is important for maintaining blood glucose during prolonged exercise and carbohydrate restriction.
9Which of the following best describes an essential amino acid?
A.An amino acid the body cannot synthesize and must obtain from the diet
B.An amino acid produced only during exercise
C.An amino acid found only in plant proteins
D.An amino acid that provides no energy
Explanation: Essential (indispensable) amino acids cannot be synthesized by the body in adequate amounts and must be supplied by the diet. There are nine essential amino acids, including leucine, which is key for stimulating muscle protein synthesis.
10Which branched-chain amino acid is most strongly associated with triggering muscle protein synthesis through the mTOR pathway?
A.Glycine
B.Leucine
C.Glutamine
D.Alanine
Explanation: Leucine is the branched-chain amino acid that most potently stimulates muscle protein synthesis via the mTOR signaling pathway. A leucine threshold of roughly 2-3 g per meal helps maximize the anabolic response.

NESTA Sports Nutrition Specialist Study Tips from Top Performers

1Prioritize the two largest areas — Performance Nutrition Science (~20%) and Macronutrient Needs & Nutrient Timing (~20%) — which together are about 40% of the exam
2Memorize key numbers: protein 1.2-2.0 g/kg/day for athletes, fat ≥20% of energy, the ~2% body-mass-loss dehydration threshold, and caffeine ~3-6 mg/kg
3Understand carbohydrate periodization and glycogen resynthesis (about 1.0-1.2 g/kg/hour for rapid recovery), not just definitions
