Keto meets carnivore in this revolutionary new book by revered cookbook author and low-carb pioneer Maria Emmerich. Did you know that our ancestors were apex predators who were even more carnivorous than hyenas and big cats? That was only about 30,000 years ago. But since then, our diets have drastically changed due to the invention of agriculture about 7,000 years ago and, within the last 100 years or so, the introduction of millions of food additives, the development of a year-round produce supply, and the hybridization of fruits and vegetables, making them higher in sugar and lower in nutrients.
