In the book the basis is .7-1g of protein per pound of lean mass (not per pound of total body weight). Then you have your 50-75g carbs. Then you make up the rest of the calories with fat so that you get a decent caloric deficit under your BMR. Google BMR and Harris-Benedict equation to figure this out. Then aim for a deficit of 500-800 calories daily or so. That is from the book.
I'd personally say to do the .7-1g of protein per pound of lean mass, then your carbs, then add some fat to every meal to keep you satiated and keep your energy level high enough.
