How long do blood sugar levels stay elevated after eating?

After eating, your body begins to break food down into usable energy. This comes in the form of carbohydrates, proteins, and fats. Carbohydrates are turned into blood sugar, which can mean that the more carbs you eat, the higher your blood sugar can rise. Foods that do not contain carbohydrates, such as meat or nuts, do not significantly increase your blood sugar levels, but may extend the time it takes carbohydrates to turn in to sugar and hit the blood stream.

How long does your blood sugar stay elevated after eating? Everyone is different. It can be helpful to monitor your blood sugar levels before and after you eat. This can give you an idea of your own personal range and help you make estimations for the future. According to the American Diabetes Association, blood glucose levels of around 10 mmol/L or below is a good goal one to two hours after a meal.¹ Speak to your doctor about determining your recommended range.
