The time between waking up and eating was a much stronger predictor of alertness than the different types of breakfast, so maybe _not_ eating breakfast at all is even better than eating a bowl of sugar? How did the authors get away with not even mentioning the strongest modifiable predictor of alertness in their study? I cannot comprehend this. Otherwise GREAT study.
