Another thing I wanted to add was nutrient partitioning, and the fact that there are too many variables to say that you can only utilize xxg of protein a day if you're a natty. Your body may become catabolic if you go too long without eating for instance. Under real life conditions, an ATHLETE will probably want to eat at LEAST a gram of protein for every half pound of total mass. So if they're 200lbs, I'd recommend at LEAST 100g unless they know what it takes for them to grow or maintain. Everyone's different. Their body, their activities, etc. I'd still prefer recommending a slightly higher protein intake but it's not a life or death matter, especially if that person isn't hell bent on putting on sheaths of muscle mass.
60g of protein is pussy... but at the same time, I'm not going to eat 500g of protein each day and stare at my stop watch to make sure I'm not getting near the realm of catabolism. Blah, can't think right now. Too lazy lol
