Sugar intake has a significant impact on energy levels. Consuming high amounts of sugar can lead to rapid spikes in blood sugar, followed by quick crashes, resulting in feelings of fatigue and lethargy. While sugars can provide immediate energy, their effects are often short-lived. In contrast, balanced meals with complex carbohydrates offer sustained energy. Reducing sugar can help stabilize energy levels, leading to improved focus and endurance throughout the day. Overall, managing sugar intake is essential for maintaining consistent energy and overall health.
