Just a personal observation: For many people, a day can potentially take a turn for the better or worse (and thus be quantified) based solely upon what they ultimately chose to fill their belly's with.
For example, last Thursday ended on a high note for me, largely due to tasting fresh goat curd cheese that, early the previous morning, had still been inside a goat.
The following evening, the day was summed up (poorly) in terms of the generous portion of Cheetos I ate, chased by three canned Diet Cokes.
Now I will say that for the average twelve year-old boy, the above pairings of food/appraisal of day would probably be reversed.
(ie: Fresh-from-the-Teat Goat Curd = Creepy Day
Copious Amounts of Cheetos and Soda = Awesome Day)
Then there's the frustrated dieter, for whom eating minuscule quantities of food- usually of questionable quality- compels them to view their day in terms of simultaneous juxtaposition.
My mom calls me and says, "I just finished my lunch. I only had two carrots with some hummus and three Wheat Thins." The tone in her voice rings of both victory, and a sense of longing that will probably go unrealized (until she hits the Edy's Cookies and Cream later on that night.)
