Night Shifts? How do you log food on them?

I would log midnight to midnight.

If you are working four days a week, consider looking at a weekly average.
On work days you eat more; on non work days, you eat less.

I work 7P-7A three times a week. I changed my diary settings from meal names, to midnight-6AM, 6AM-noon, etc and log the meals in the correct time periods. I keep the midnight to midnight calories that MFP uses, I just find this the simplest way, rather than have food logged in all sorts of different length days. Works for me.

I don't do night shift but if I was I think I would be logging either on the day I eat it so after midnight and I log it the next day.

Or if I have multiple night shifts in a row log everything before I sleep on one day and start the next day when I wake up.

My day runs from 4 pm until 8 am the next day. It all gets charted under the day it was when I started at 4 pm. If I end up being up some during the day I log my food where ever it will fit and not make the day go over. I figure this makes my weekly calories add up right.
As for snacking, I usually try to preplan and prelog most of my food choices for the night. It is so hard at work because people constantly bring in food to share.

Goth time. If I haven't passed out yet, it's not tomorrow yet. No matter what the clock says. I log all foods eaten before I sleep my 6-8 hours on the day I woke up, then the next time I wake up is the new day. It makes it simpler for me. I already dislike math, no reason to go adding additional complications (pun absolutely intended.)

I go from midnight to midnight every day. It's just so much easier because some days I sleep right when I get home from work and other days I don't go to bed until later. 12-12 never changes.

Midnight to midnight for me too. I also gave up on snacking through the night. I take a small meal with me usually dinner leftovers and aim to eat that half way through my shift. I drink a ton of water and nothing sugary as it just increases my craving for snacks. Your shift pattern seems hard going. Best of luck.

I used to work nights at a group home. I would take ensures or slimfast with me depending on how I felt. But I was also homeless/just getting back on my feet at the time and stressed beyond appetite and lacked appetizing food too. So drinking meals made It easier for me to stomach them and helped me get my desire for food back. That being said, it worked for me in that situation. But night shifts also always messed up my stomach especially if I didn't sleep during the day. I can't say my advice is really all that healthy but it is practical and has to be more healthy than junk food. I would stay away from slimfast though. I've learned too much since then. But liquids of some sort like soup maybe be easier on your stomach if you get the same issues I get. But ensures, or protein bars like powerbar, or nutragrain bar, might help keep things manageable along with tons of water also. Preportioned raisins, or nuts ,dried fruit.....I started taking those as my money and appetite came back. Also plan out your snacks before work, take them with you and stick to it. It has to be cheaper than the vending machine or gas station Crap you're probably eating anyway. Just some ideas, take what you can and leave the rest.

I try not to eat any food/snack, only drink one energy drink or coconut water. Then get home after work and sleep first thing in morning. I eat after I woke up at afternoon. Eating any snack at night-morning make me to lose control. If I'm too hungry and have to eat, I limited myself to a 100 calories snack. It was only thing that worked for me. I log after midnight.

I log food when I eat it. I really don't care if I have my logging separated into special meals though. But I log it on the day I eat it.
