I have heard this my entire life and I agree. But why? Is it really the most important? If so, is there a type of food that is more important than another? Are you supposed to have high carbs to burn throughout the day? High sugar, for a quick burst of energy? Citrus? Protein? Should it be a big meal since you haven’t eaten in hours or a small meal since you haven’t eaten in hours?

Does anyone know anything about what is BEST for us first thing in the morning?
