Chow has an interesting thread going about when people eat, what and why. My response is below:
weekdays: oatmeal with raisins around 9 am at work, occasionally a snack of cheese and crackers or fruit mid-morning, lunch of leftovers at my desk anytime between 11 and 2, snack of yogurt and raisins or crackers mid-afternoon, snack of popcorn or cheese and crackers (i like cheese and crackers, you see) at home around 6, dinner around 8, usually rice or pasta based with a glass of wine. on rare occasion, will have a cookie or a few spoonfuls of salted caramel (thank you, bi-rite) ice cream after dinner. i don't love sweets.
weekends: decaf coffee with milk and sugar whenever i wake up. eggs of some sort an hour or so afterwards. snack (popcorn, fruit, or chips) in the early afternoon or lunch depending on when i woke up. dinner out or take away, usually around 7/8.
i eat when hungry, out of necessity. i get very cranky, nauseous, and tired if i don't eat as soon as i am hungry. however, the food choices are usually purely for pleasure, although i like to use up the contents of my csa box for health reasons. hopefully those vegetable experiments turn out pleasurable as well.
