Carnivore is all the rage lately and for pretty good reason. It helps people rapidly lose weight and/or heal from a variety of chronic diseases and ailments. You can read through a plethora of personal stories on MeatHeals.com (see stories by category from the list in the right column).

Why would the equivalent of eating toilet paper be something healthy for humans? Fiber is a non-nutritive substance we can’t digest.

So why do we think...
