You probably don't need 40% of protein for building muscle. The known evidence points to 1.5g per kg of body mass (~=.75g/lb) being more than enough. In my case

You probably don't need 40% of protein for building muscle. The known evidence points to 1.5g per kg of body mass (~=.75g/lb) being more than enough. In my case that works out to about 20%.
