Matt, if you and I both were 200lbs, do you think your bodies are the same and work the same?
What I am saying is each persons body will use the food they eat differently. Your body may only be able to handle 250grams of protein, but mine may be able to handle 500grams of protein.
These charts are just assumptions and not based on any real data.
How much protein does your body need????? Those numbers on that chart are probably alot higher than the amount your actually need. But if you have goals such as gaining mass, well..... you have to eat according to those goals. Increase calories and make sure you eat lots of protein.
