80% lean ground beef is great, except for the risk that it can come from sick cattle. Its estimated 25% of ground beef can come from sick/diseased animals. If you know they ground it themselves from the grocery store and its fresh then go for it. Saturated fat should be your main source of energy, after all, people have VERY little storage capability for carbs, but have unlimited ability to store fat, your PRIMARY energy source, if u just allow it to happen. Do this by cutting out carbs and eating protein and fat. After all, excess carbs are stored as body fat, u know what type, saturated fat, the energy u r meant to run on. But if you eat it, u have to cut out your carbs, at least below 100g a day, b/c high carbs and high fat will just make you fat. By the way, great price, where'd u find it that cheap at?
