Appeal to authority. Yeah and Shaw hits Gear. Who Cares. Countless other "doctors" also looks "healthy" and can back up their claims with scientific studies and professional opinions too. The covid Vaccine has studies backing it too.
It is absolutely true that for short and long term health you need head to toe animal nutrition. All the blue zones eat some form of raw organ meat, especially for pregnent women, all traditional hunting societies, as featured in Weston A. Price studies, went right to splitting up the organs after a hunt, eating it before it bsgan to rot. The diets of pre-sedentary societies with optimal health and physique, did not just eat a grilled out steak. Certain hormones and other nutrients are found in greater available quantities in organ meats. Raw organic egg yolks were also sought out, fish ect.
Many people have abandoned the standard "carnivore" diet after years because it suffers from a nutrient difficiency similar to veganism, despite it being better than carb and SAD based diets. They often go back to eating plant foods, not realizing that what was missing was organs.
