Eat your dry chicken breasts and Brocolli.
I will eat hamburgers and cookies and be leaner and stronger.
In fact. I am leaner right now than you. Perhaps all that protein you are eating is a waste.
Maybe you should apply theroies based from an ectomorph body type to represent those mesomorphs, Ive been eating my fair share of "regualr" foods still, just in moderation..nothing new.
I had a slice of pizza for breakfast on the weekend. I had a cookie yesterday too! And on Sunday I enjoyed some Coldstone...

I have said it before in the past, I could never reach the 1-1.5 grams a protein per lbs of bw as the pros suggested.. some days I can, like maybe five or six days a month...
I think its all propaganda since five -six years ago.
