Not enough worth in teh bodybuilding community is given to the bioavailability of protein.
Just as we know meats and dairy due to their amino makeup are more easily absorbed proteins, having an adequate supply of the alkaline minerals and glycogen-along with not being hypothyroid- allows for more of the protein to be used for muscle building/repair,not properly digested, etc. then used for something like making energy as one would while low carb, as an example.
I think that's one of the reasons why I had issue gaining muscle while low carb.
So, from a biologist with a PHD, not me, when you eat a few eggs, drink a glass of milk and some OJ to access all that protein from the egg. With meat have a sweet coffee maybe,etc or some coke and milk again for calcium, the coffee also helps prevent absorption of iron from red meat, and I think the iron problem is the real reason whymeat eaters suffer cardiovascular issues as there is much more proper science detailing the negatives of too much iron .
