rather, my rule for most of my life has been that i eat when i'm hungry, rather than that i eat at a specific time of day. and, that's a big part of why i'm designing this how i'm designing it - i know i can't and won't eat three times a day, and it will be a struggle to force myself to eat twice a day.
in the end, i may let my iron stores fall, or even choose to take supplements rather than force myself to eat more than my body urges me to. but, i need to make sure i can absorb it before i decide how to react.
