Answer to Question 1
ANS: C
In general, when energy requirements are completely met by kilocalorie (kcal) intake in food, weight does not change. When kilocalories ingested exceed a person's energy demands, the individual gains weight. If kilocalories ingested fail to meet a person's energy requirement, the individual loses weight. Fluid, not kilocalories, causes daily weight fluctuations.
Answer to Question 2
ANS: B
The basal metabolic rate (BMR) is the energy needed at rest to maintain life-sustaining activities for a specific period of time. The resting energy expenditure (REE), or resting metabolic rate, is the amount of energy an individual needs to consume over a 24-hour period for the body to maintain all of its internal working activities while at rest. Nutrients are the elements necessary for body processes and function. Nutrient density is the proportion of essential nutrients to the number of kilocalories. Highnutrient density foods provide a large number of nutrients in relation to kilocalories.
