first, pemican is not cooked meat. It is cooked fat. I think you know that, and it's a typo on your part, for you have written about the heated fats before. Next, I have for the last two weeks, heated my fat after putting it through a food processor. The tempurature of the fat never goes above 100-105. A rich golden yellow liquid, entirely delicious, separates from the fat tissues. I skim off that with a spoon and eat. The remaining fat/tissue not unlike a creamy hot cereal in texture, I eat with a spoon also warm, and it is easy to swallow the liquid out of the mixture and not swallow the tissue parts. I end up with a tablespoon or so of fibrous material. I can tell you that my stool amount has shrunk dramatically, just from doing this. It's not hard for me to imagine that if I powered my meat and simply had liquid fat as described above, that my stool amounts would even decrease another substantial amount. Or in other words, as Delfuego writes or suggests, that his digestion of the ingested material is so efficient that not much remains. My raw dogs eating whole lamb as wolves would in the wild pass large stools that soon turn white in the fields from eating the bones along with meat of the whole lamb. They also throw down their throats materials like tendons etc, that are far from being completely digestible.
Before we dismiss Delfuego as crazy or whatever else he has been described as, we might like to actually try ourselves what he does. After just watching Aujonas on the DRs program, like those doctors who have no real experience of eating meat raw, and then go on to make their highly prejudiced remarks, we too maybe should have some direct experience before sounding so sure.
Remember, in carb eaters, at least one half of the stool mass is from the bacteria that feed on the carbs. A zc eater doesn't have that bacterial mass exiting or needing to exit. I say needing to exit, for the acidic content of bacterial wastes can build to such a point that it can irritate the colon. It is also one of the main factors contributing to peristalsis in carb eaters. The acid level signals the colon to contract. Also we have very limited ability to digest vegetable fiber, also contributing to mass or volume of stools.
