Dietary changes that can help regulate blood sugar levels include reducing refined carbohydrates and sugars while increasing fiber intake. Choosing whole grains, vegetables, and legumes can stabilize blood sugar spikes. Combining proteins and healthy fats with carbohydrates can slow digestion and improve glucose management. Regularly scheduled meals and snacks promote steady energy levels. Monitoring portion sizes and avoiding excessive snacking also contributes to better blood sugar control, essential for overall metabolic health.
