Good thing I quit cereal years ago and replaced it with good ole Quaker Oatmeal. I work out in the very early AM before work and after an exhausting workout there is absolutely no better source of quick enery than oatmeal.
I put salt, sugar, butter and sometimes heavy cream on my oatmeal.
Absent the availability of some or all of those things, I have been known to put ketchup or even Worcesterchire sauce.
