What role does physical activity play in relation to diet?

Physical activity plays a crucial role in maintaining a healthy weight by utilizing energy and burning calories. When individuals engage in regular exercise, they create a caloric deficit, which helps balance the energy they consume through food. This process contributes to weight management and can prevent obesity, among other health benefits.

Regular physical activity is also linked to numerous positive outcomes beyond weight control, including improved cardiovascular health, stronger muscles, and enhanced mood. It can promote better eating habits as well, reinforcing the link between a balanced diet and an active lifestyle.

The other options do not accurately reflect the positive relationship between physical activity and diet. While it’s true that physical activity can increase appetite in some people, this effect can lead to healthy eating choices if managed correctly. The assertion that physical activity has no impact on health contradicts extensive research highlighting its benefits. Lastly, while there can be short-term feelings of fatigue after intense exercise, regular physical activity actually enhances overall energy levels in the long run. Thus, the significance of physical activity in maintaining a healthy weight reinforces why it is a correct choice in this context.
