What impact does physical activity have on nutritional needs?

Physical activity significantly impacts nutritional needs by increasing caloric and nutrient requirements. When engaging in physical activities, the body expends more energy, which necessitates a higher caloric intake to maintain energy balance and support overall function. This increase in energy expenditure means that individuals who are physically active need more calories than those who lead a sedentary lifestyle.

Additionally, physical activity can elevate the need for specific nutrients, such as proteins to aid in muscle repair and growth, and carbohydrates to replenish glycogen stores depleted during exercise. Essential nutrients like vitamins and minerals may also be needed in greater amounts for energy metabolism and recovery processes. Thus, to optimize performance and health, individuals involved in regular physical activity must adjust their dietary intake accordingly, making choice C the most accurate regarding the effect of physical activity on nutritional needs.
