Nutrition plays a critical role in maintaining energy levels throughout the day. Consuming a balanced diet rich in complex carbohydrates, healthy fats, and proteins ensures a steady supply of energy. Foods with high fiber content, such as fruits, vegetables, and whole grains, prevent energy spikes and crashes. Staying hydrated is equally important, as even mild dehydration can lead to fatigue. Incorporating small, frequent meals can also help maintain stable energy levels and optimize metabolism throughout the day.
