How long in minutes after a meal will blood glucose level be highest for a type 2 diet control diabetic?

Peak of blood sugar: Blood sugar generally peaks one to two hours after a meal. This number is just as important as fasting blood sugars are.

An hour: Depending upon your personal glucose tolerance curve, the highest blood sugar would occur in the one-half to one hour range.

At 45-60 minute: But can also happen at 30 minute depending the type of food being ingested ( fatty food mixed with carbs tends to delay the absorption of glucose from intestine).
