I've read articles, and read some more articles, and I'm none the wiser. Here's some info about me:

260lbs (approx 182lbs lean body mass)
Just under 6 feet
I go to the gym 3 times a week to do stronglifts (5x5x5)

I have calculated my macro needs using Robb Wolf's troubleshooting thingy and after reading Mark's article on here, this is what I came up with:

Protein: at .5g per pound = 91g

Carbs: 75g

Fat: this is what I'm finding to be way over the top. Apparently I will need 230g a day!!! It just seems way in excess...THat's 76g per meal (I eat three times per day).

Could somebody please help me out here as I am really floundering.
