A balanced diet significantly impacts energy levels by providing essential nutrients that fuel bodily functions. Consuming a variety of macronutrients—carbohydrates, proteins, and fats—ensures sustained energy throughout the day. Carbohydrates serve as the body's primary energy source, while proteins aid in muscle repair and recovery. Healthy fats are important for hormone production and nutrient absorption. Inadequate or imbalanced nutrition can result in fatigue, mood swings, and decreased motivation to exercise. Overall, a well-rounded diet supports optimal energy levels for daily activities and workouts.
