This study showed that there was more muscle protein synthesis after consuming 25g of protein vs. consuming 25g spread out over multiple servings.
A lesson to be learned with protein is that “pulsing” is more effective at increasing muscle protein synthesis than constant infusions of smaller amounts. So having two big protein meals a day can be a bigger net gain than trying to eat a lot of small meals with some protein in them. This is similar to how you maintain better insulin sensitivity by not constantly putting a small amount of carbs in your mouth vs. just eating one large amount and then giving your pancreas a break for a while.
