Mack is not "GOD"....he is an extremely knowledgeable bro who knows what works FOR HIM.....he can't tell you what will work for you. I promise you, if you eat 4ozs or 8oz, you will never look like he does. You may look awesome, but not the same as him. Point is, it's trial and error........find out what works for you and do it.....personally, I need HIGH HIGH fats and mod/ to low carbs with high protein. Some like high carbs, to each his own.
