Between 50–60% of protein becomes glucose and enters the bloodstream about 3–4 hours after it's eaten. Don't eat fruit, fruit juice, or a "sweet" (often called fast-acting carbohydrates) for a snack without also eating protein. The protein will slow the absorption of carbohydrate. So this being said, you need the carbs to be able to absorb first and fast then wait and consume protein from what my coach says 20 minutes due to the spike AM was mentioning. Then eat your carbs with protein the rest of day to slow the absorption of it.
