I agree with P-Dog. Don’t really know where you got that info. Obviously, it all depends on when you train when you want to spike insulin and enhance protein synthesis and prevent protein breakdown. Post training, you want to ingest around a 2:1 ratio of carbs:protein per lb of lean body mass. Carbs will induce an insulin spike which will then shuttle those nutrients to muscle cells
Now I may be wrong in what I am about to say, but anytime you eat, insulin will be released. However…increased protein stimulates the release of glucagon which is a insulin antagonist (meaning it draws glycogen AWAY from muscles), so I dont think you need to worry about an increased insulin spike at night if you eat a meal consisting of 30+ grams of protein. Because protein results in glucagon being released…it stands to reason that you don’t want to eat a HUGE protein meal right after working out. Thats why it is pretty pointless to eat a meal consisting of upwards to 70,80,90 grams of protein (unless of coarse you are Hyyyoooge) as a P+C meal after training. It would just inhibit insulin’s job in shuttleing those nutrients into muscle. Thats why your best bet is to just divide your protein intake between your 6-7 meals which is usually 30,40, maybe 50 grams of protein per meal. Does that make sense? Man, I hope I am not wrong (I dont think I am), but I am sure someone will come along and let us know…haha.
