From The Rosedale Diet by Dr. Ron Rosedale

"If high carbohydrate wasn't the right approach, that left two other  
major food categories on which to base a diet: protein and fat.  It  
may surprise you to learn that the protein the body doesn't quickly  
use to repair or make new cells is largely broken down into simple  
sugars, which increases blood sugar and promotes insulin resistance.   
Furthermore, protein itself triggers insulin production, which can  
worsen insulin resistance."

Rosedale recommends no more than three to five pack-of-cards-sized  
portions of lean protein a day.
