Dietary changes that can improve energy levels often focus on incorporating a balanced intake of carbohydrates, proteins, and healthy fats. Complex carbohydrates, found in whole grains, fruits, and vegetables, provide sustained energy rather than the quick spikes associated with simple sugars. Incorporating adequate protein aids in muscle recovery and helps maintain energy throughout the day. Staying hydrated also plays a significant role, as dehydration can lead to lethargy. Including foods rich in iron, such as lean meats and spinach, can combat fatigue. Ultimately, a nutritious and balanced diet supports overall energy and vitality.
