Which of the following can be a consequence of poor nutrition on physical performance?

When considering the effects of poor nutrition on physical performance, decreased performance is a significant consequence. Nutrition plays a crucial role in fueling the body for exercise and activity. A diet lacking essential nutrients can lead to insufficient energy levels, reduced stamina, and impaired muscle recovery. This, in turn, affects overall athletic performance, making it difficult to maintain intensity and endurance during physical activities.

When the body doesn't receive the necessary vitamins, minerals, carbohydrates, proteins, and fats, it cannot function optimally. This may manifest as fatigue, decreased motivation, and a lack of strength and coordination. The body's systems, especially the muscular and cardiovascular systems, rely on proper nutrition to perform at their best.

The other options highlight positive outcomes related to good nutrition rather than reflecting the adverse effects of poor dietary choices. Increased energy, enhanced recovery, and improved focus are all benefits that come from a well-balanced diet, emphasizing the stark contrast between good nutrition and the drawbacks of nutritional inadequacies on physical performance.
