There a numerous studies out there that show that excess protein is not as beneficial as many believe. It increases protein catabolism throughout the body and forces the requirement of excess protein intake. Also, there is not a solid link between excess protein intake and muscle development. Last study on this that I read showed that, so long as an individual is getting the base amount of protein required for that person, muscle production in response to exercise is the same as one who is taking excess protein.
It's more important to get the correct amount of protein than an excessive amount of protein.
In this case, compound exercises for a full body workout, proper nutrition, and a combination of fat-burn and HIIT cardio training is the way to go.
