Energizing the Writing Brain

Supposedly, the act of writing is one of the cognitive activities that requires the most energy by the brain. That being said, is it interesting to think about what had been eaten by the author of a piece of writing you are currently reading (or have read in the past)?

If your answer is yes, then lets see... [what did I eat which is powering my human engine to write this piece?] It was some combination of roasted hemp seeds and a fried-egg sandwich with mayonnaise!
