Snacking when you have diabetes: MedlinePlus Medical Encyclopedia

Learning how to count the carbohydrates that you eat (carb counting) helps you plan what to eat. It will also keep your blood sugar under control.

Your health care provider may tell you to eat a snack at certain times of the day, most often at bedtime. This helps keep your blood sugar from getting too low at night. Other times, you may have a snack before or during exercise for the same reason. Ask your provider about the snacks you can and you can’t have.

Needing to snack to prevent low blood sugar has become much less common because of new types of insulin that are better at matching the insulin your body needs at specific times.

If you have type 2 diabetes and are taking insulin and often need to snack during the day and are gaining weight, your doses of insulin may be too high and you should talk to your provider about this.

You will also need to ask about what snacks to avoid.
