fCAT: innovative peace leadership: WELLNESS TIP: EXERCISE TO BEAT DIABETES. Diabetics are always told to increase their physical activity and lose weight. This is because, when you’re exercising, your body derives energy from glucose reserves of your body. When that stored glucose is exhausted, your body extracts glucose from the bloodstream. This causes a drop in blood glucose levels. After your finish exercising, your liver restores the exhausted energy reserves, which further helps to reduce blood sugar levels. Regular exercise also increases your sensitivity to insulin. It also helps to burn fat, lower blood pressure cholesterol and improves circulation.
