To maintain healthy blood sugar levels, individuals should focus on a balanced diet that includes complex carbohydrates, proteins, and healthy fats. Regular physical activity, such as walking or strength training, can improve insulin sensitivity. Hydration is also essential, as water helps to regulate blood sugar. Monitoring portion sizes and limiting added sugars or processed foods can further aid in maintaining stable blood sugar levels. Incorporating foods rich in fiber, like fruits, vegetables, and whole grains, enhances satiety and supports healthy metabolic processes.
