30 - 45 minute window
 

The 30 - 45 minute window after training or events is a crucial time during which the body races to recover as quickly as possible. The body's evolutionary instinct to immediately replace muscle glycogen (our first and main source of energy) means that it will use whatever nutrients are available, including amino acids present in muscle tissue, resulting in muscle wastage.

I think I read something else you wrote that goes along with this saying that a certain percentage of you carbs should be eaten post work out. I try and eat a lot of brown rice post work out along with a weight gaining shake.
