missmeow 156 Posted March 4, 2013 During weight loss, you are on low calories. The Protein helps in healing and keeps you from cannibalizing muscle, such as heart muscle. Keep the Protein high and you ensure fat loss without muscle loss. During maintenance, which I am assuming is the question since the OP is 1.5 years out, I have no idea. I would guess that given the limited portion size the protein keeps you satiated and less likely to snack.< /p> Share this post Link to post Share on other sites
