How is Type 2 Diabetes Treated?

Before starting medications, generally the first step to treating Type 2 Diabetes is improving your lifestyle. Your healthcare provider can give you personalized information, but here is an overview:

Eat healthier and lose weight

Improving your diet and losing weight are key parts of managing type 2 diabetes. [1,2] Even losing 5-10% of your body weight can meaningfully improve control of your blood sugar.

Eating foods high in fiber (including vegetables, fruits, whole grains and legumes), low-fat dairy products and fresh fish can all contribute to a healthier diet. You should also avoid foods that are high in saturated fat and decrease your intake of sweet deserts and snacks. [3-5]


Healthcare providers generally recommend as much physical activity as you can tolerate. If you can, you should aim for at least 150 minutes of moderate exercise per week (example: 30 minutes, five times per week). [6]

Great examples of moderate physical activity include aerobics, resistance and flexibility training. Aerobic exercise is any exercise that causes your body to use more oxygen, and thus increases your heart rate. This includes activities such as brisk walking, cycling or swimming.

If you have difficulty moving for any reason, exercising as tolerated is still highly encouraged. Talk to your healthcare provider for more information.
