This mainly pertains to ground beef . If you cook 80% gb and turn it into meatloaf . When you cook it a lot of th fat comes out and I scrap it out I to the trash . I have found charts online claiming that when you cook the beef the calories actually are lower from losing the fat and I'm wondering if there's any truth behind this? Seems logical to me . And cost effective bc 80% beef is always cheaper then the 93% and I can find it easier in larger packs .
