Although only recently fashionable, scientists have long been intrigued by this very low-carb way of eating known as the Carnivore Diet.
As early as 1797, researchers attempted to replicate the traditional meat-based dietary intake of Arctic or nomadic societies by imitating their traditional meat-rich diets. Dr. John Rollo made history when he successfully treated patients with type 2 diabetes using a diet consisting of predominantly meat and fat after studying indigenous people's very low-carbohydrate diet of St. Lucia; it soon became a widely adopted therapy until insulin was discovered in 1921.
