Bullet proof coffee is a foamy invigorating drink created by Dave Asprey and has become the toast of breakfast mornings in Silicon Valley. Made from Coffee, Butter and Oil, its listed benefits are many: It triggers weight loss by way of ketosis, a metabolic state triggered by a lack of carbs that kicks fat-burning into overdrive; it kills annoying cravings; and it enhances cognitive function, injecting a dose of mental lucidity into your foggy morning brain! This coffee is intended to be efficient, easy way to gulp down fats and calories without processed carbohydrates. But dieticians and nutritionists say that a tablespoon of good old fat in the morning helps line up the gut, switching fat to fuel instead of carbs and keeps insulin levels stable and of course, one cannot neglect the importance of a healthy diet, happy mind and exercise!
