A fitness client wants to lose 1 lb of fat per week. Approximately what daily caloric deficit is required to achieve this goal?
Answer: 500 kcal/day
One pound of fat contains approximately 3,500 kcal; a 500 kcal/day deficit over 7 days yields a 3,500 kcal weekly deficit.
Which electrolyte is the primary intracellular cation and plays a key role in muscle contraction and nerve transmission?
Answer: Potassium
Potassium is the dominant intracellular cation and is essential for maintaining the resting membrane potential and enabling muscle and nerve function.
What does the term 'nitrogen balance' indicate in the context of protein metabolism?
Answer: Whether protein intake equals, exceeds, or is less than protein breakdown
Nitrogen balance compares nitrogen intake from protein to nitrogen losses; positive balance indicates net protein synthesis, negative indicates net breakdown.
A client who is lactose intolerant avoids all dairy. Which non-dairy food provides the highest amount of dietary calcium per serving?
Answer: Canned sardines with bones
Canned sardines with edible bones provide approximately 325 mg of calcium per 3-oz serving, more than most plant-based alternatives.
Which macronutrient provides 9 kcal per gram, more than twice the energy density of carbohydrates or protein?
Answer: Dietary fat
Fat yields 9 kcal/g compared to 4 kcal/g for both protein and carbohydrates, making it the most energy-dense macronutrient.
Which dietary pattern is most strongly associated with reduced risk of cardiovascular disease based on current evidence?
Answer: Mediterranean diet
The Mediterranean diet, rich in olive oil, vegetables, legumes, fish, and whole grains, has the most robust evidence for reducing cardiovascular disease risk.
What is the primary function of phosphocreatine (PCr) in skeletal muscle during high-intensity exercise?
Answer: Rapidly regenerating ATP from ADP
Phosphocreatine donates its phosphate group to ADP via the creatine kinase reaction, rapidly regenerating ATP during the first 5–10 seconds of maximal effort.
