wouldn't think of not using grass-fed only. Your choice. But I'd take a paper route to supplement income if I had to. In my opinion, you're overeating, if you're still eating five pounds of meat a day. Even Shawn Baker who is huge and works out like a fiend, eats around four pounds. And most in this field think he overeats. Too often we think more is better. But how about eating as little as possible, ensuring that everything you put in your mouth is utilized completely. Some think that excess protein cause mineral imbalances, not to mention stress on the body. Liver, which I know you do in copious amounts solves my cramping. But taken in excess, or more than the body needs and wants, I have no idea as to the resultant. Again, by blending your foods, you will never know how much in the moment your body is desiring. That's why I continually point out here, that to learn to listen to your body, to let it tell you what it needs as opposed to you telling it what you think it needs, one should take a bit at a time of fresh (unfrozen) meat/food at a time and see if you do indeed want another.
