It can never really hurt you to have a good source of protein before you go to bed. Your body is going to be, pretty much, catabolic. Remember now, you're out for six, seven, or eight hours, hopefully, which is extremely important.
Most people are not getting enough sleep. Without proper sleep, believe it or not, it's more like nine hours, but for some people that's virtually impossible. Without proper sleep, your body is not going to make muscle and burn fat.
The catabolic hormones are raging throughout the day. The gains that you do see are going to be minimal, at best, and you're literally cutting years off of your progress by not getting enough sleep.
While you're sleeping, your body is not getting any nutrients. It's always a good idea, especially, if you're someone who trains hard, and someone who's looking to make muscle, to add a little bit of a protein supplement before you go to sleep.
It could be a Casein, slower digesting protein. It could also be a blend. You could add some glutamine, or even some other amino acids in the mix. Those are going to help keep cortisol at a minimum while you're sleeping.
I recommend usually a couple scoops of glutamine, 5 to 10 grams minimum, into a protein shake, before someone goes to sleep. Their body will be fed this protein while they're sleeping.
You'll wake up in more of an anabolic state. The shake will be digested already, it's just a matter of whether or not you've done enough to protect the muscle tissue that you work so hard for during the day.
We've said it before. Don't eat at night. It's never good to eat carbs, specifically, at night, because carbs turn to fat. That's another topic for another discussion. Carbs don't turn to fat again. It has to do with calories in and calories out.
However, it's important to remember, it's when you work out, how long and hard you work out, relative to what that meal is going to be, if you are going to eat something late at night.
Just because you're eating something at night doesn't necessarily mean that it will be stored as body fat. In fact, if you have the kind of a body, clock, and a schedule, where you're working out at night, maybe even working out at the early evening, but not getting done until 9 or 10 o'clock, you've changed your whole bodies needs at that point. You can eat, sometimes even a meal, after that. Your body will be starving for recovery.
Everything that you've heard about eating carbs at night goes out the window, or even about not eating at all. Your body is going to be using those foods to repair, recover, and grow your body, even while you're sleeping.
