Nutrition profoundly affects energy levels during exercise. Consuming adequate carbohydrates is essential, as they serve as the primary energy source for physical activities. A balanced diet with carbohydrates, proteins, and fats ensures that the body has the necessary fuel to sustain performance. Dehydration can also impact energy levels, making proper hydration vital for optimal physical function. Timing of meals and snacks can further influence performance, as eating too close to exercise may cause discomfort. Following sound nutritional practices helps maintain consistent energy levels, enhancing overall workout performance.
