Dietary changes can improve energy levels for workouts by ensuring adequate intake of macronutrients and micronutrients. For instance, consuming a balanced meal that includes complex carbohydrates provides sustained energy, while protein aids in muscle repair and recovery. Foods rich in essential vitamins and minerals, like iron and magnesium, can enhance overall energy metabolism. Hydration also plays a key role; staying hydrated prevents fatigue during workouts. Ultimately, optimal nutrition fuels performance and supports endurance.
