I may get flamed for this one... This is one of the reasons why I think training in the early AM is superior. The research PROVES you have a far more efficient insulin response in the morning than later in the day, probably because your kidneys aren't tired out. And I agree that post workout is Ideal for an insulin spike. Therefore, to accomplish a massive and efficient insulin at the optimal time (post workout, when anabolism is most appreciated), have a small protein/carb/fat meal when awaken, then drink a super fast absorbing post workout shake when you finish. badabing badaboom
