Interesting thoughts here Times. I recently watched a YouTube video of Dorian Yates speaking on nutrition. His suggestions were 1-1.5g/lb of body weight for protein intake and double that for carb intake to start and then adjust from there depending on how carb sensitive you are. So that throws the traditional 40/40/20 out the window and to a degree helps to reinforce the theories you just put forth.

In my early days of training it was all about the protein. I made sure to eat my proteins first in my meals and then eat my carb source after until I was full. It wasn't until I reversed that idea that I really started to see fast growth. Now I start my meals with my carb source and the move on to the protein until I can't put in another bite. This new method has given me a 30lb weight gain over the past year with only a 4-5% increase in body fat.
