"If you drink coffee, the caffeine in the coffee will bind to adenosine receptors in the central nervous system and stop these adenosine receptors from doing their job, namely down-regulating the central nervous system. In addition, caffeine also promotes neurotransmitter releases that further stimulates the central nervous system. As a result, for a short period of time, drinking #coffee will give you the illusion of being less tired, more alert, more energetic, and even more creative. In reality, behind the scenes, caffeine does no such thing. #Caffeine simply stops your body from functioning as it should." www.allthingscarnivore.com/should-you-drink-coffee-on-the-carnivore-diet
