Which hormone, secreted by adipose tissue, signals the hypothalamus to suppress appetite and increase energy expenditure?
Answer: Leptin
Leptin is released by fat cells in proportion to fat mass and acts on the hypothalamus to reduce hunger and up-regulate metabolic rate.
A vegan client reports fatigue, numbness in the hands, and megaloblastic anemia. Which nutrient deficiency is most likely?
Answer: Vitamin B12
Vitamin B12 is found almost exclusively in animal products; deficiency causes megaloblastic anemia and neurological symptoms and is common in strict vegans.
What is the recommended carbohydrate intake range as a percentage of total daily calories for active individuals, according to general sports nutrition guidelines?
Answer: 45–65%
The Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates is 45–65% of total energy, aligning with sports nutrition guidelines for active people.
Which supplement has the strongest evidence base for improving high-intensity, short-duration athletic performance such as sprinting and weightlifting?
Answer: Creatine monohydrate
Creatine monohydrate is the most extensively studied ergogenic aid and consistently improves maximal strength, power output, and repeated sprint performance.
Which amino acid is the rate-limiting precursor for serotonin synthesis and may influence mood and sleep when consumed in the diet?
Answer: Tryptophan
Tryptophan is converted to 5-hydroxytryptophan (5-HTP) and then to serotonin; dietary intake influences central serotonin levels and related mood and sleep regulation.
What is the key difference between soluble and insoluble dietary fiber?
Answer: Soluble fiber dissolves in water and forms a gel; insoluble fiber does not dissolve
Soluble fiber dissolves in water to form a viscous gel that slows digestion and lowers cholesterol, while insoluble fiber adds bulk and speeds intestinal transit.
Which of the following best describes the concept of energy availability in the context of the Female Athlete Triad?
Answer: Dietary energy intake minus exercise energy expenditure relative to lean body mass
Energy availability = (dietary energy intake − exercise energy expenditure) ÷ fat-free mass; low energy availability disrupts hormonal function and bone health in the Triad.
