, ESTUDYR
B. 198 kcal
C. 198 kcal (22 g × 9 kcal/g = 198 kcal)

Rationale: Fat provides 9 kcal per gram (22 × 9 = 198).
Dietary Reference Intakes address the nutrient needs of:
A. Only children
B. Only pregnant women
C. Most healthy population groups
D. Only athletes
Rationale: DRIs are designed for apparently healthy populations across life stages.
Overnutrition is best described as:
A. Eating too few calories only
B. Excess nutrient and energy intake over time
