I tend to think about it from a different perspective. I have heard the argument a thousand times that "You dont need that much protein" when they hear I am over 350 grams per day. What I tell them is I DO NEED 3200 calories a day to hold me lean while working out and doing cardio and I have 3 choices to get them from. Now if I cut drop the protein to 175g a day that means I would need to get 2500 calories a day from carbs and fat. Figure that to be around 100g of fat an additional 400g of carbs per day which does not work for me when it comes to dropping bf.
