Essential nutrients for maintaining energy levels include carbohydrates, which serve as the primary fuel source, and proteins, which aid in muscle recovery. Healthy fats also contribute to sustained energy release. Micronutrients such as B vitamins are crucial for energy metabolism, while hydration is equally important in maintaining optimal physical performance. Incorporating a variety of whole foods, including fruits, vegetables, and whole grains, ensures adequate vitamin and mineral intake. This balanced approach supports consistent energy for daily activities and workouts.
