Midnight Shift

Hi OP! I work 6p-6a for four days then I am off four days...well nights. I had the same problem when I first started tracking my calories. I read multiple posts about people's ideas and chose one that made sense to me. Those ideas boil down to:
* track everything you eat while awake on the calendar date it is when you wake up
* track everything you eat while awake on the calendar date it is when you go to sleep
* track everything you eat when you eat it and it will most likely be half each day (if it's confusing to track CICO by days this way, look at the weekly picture and make sure you are in a weekly deficit)

But it's best to stick with one way so your tracking history will remain consistent.

I would start a new "day" when you wake up and keep it on the same "day" until you go to bed, that way you can evaluate it as a chunk that belongs together and not have your breakfast llogged one day and lunch and dinner the next.

I work 10pm - 6am 3 nights a week, then a double - 10pm - 2pm (16 hours) on the last day. I've found it very hard as well to figure out how best to track what I eat, as it switches hours on my nights off, as it does for you it sounds like. I have chosen to go with midnight to midnight, it seems to be working for me.
