Does anyone input their food ahead of time?

I do. I do not currently have a smart phone so I have to do all my updating on an ipod touch or my computer. I input my breakfast and what I plan to eat for lunch before I leave for work in the morning and then update again for dinner and I try to plan my snacks and input them ahead of time too.

Yep I always log my food the night before. I make sure Ill have enough protein to sustain me throughout the day and that I'm under my calorie limit of course. I find it helps me stress less about what I'm going to eat throughout the day. And it keeps me from binging when I don't feel so restricted and ball and chained to immediately logging into MFP.

I'm a bit obsessive about it actually. I have my diary planned a few days in advance. I find it helps me make better choices instead of trying to figure it out as I go.

I just started this on Tuesday and figured out right away if I enter my workouts and meals then I am more likely to stick to it since it is there in writing.

Yes I "pre-order" my calories just to save some time. I know what I have in my lunchbox and I add beers prior to a night out to guage my exercise time to keep me in "the good".

I pre-log quite often and highly recommend it to people that are just starting out.

Logging ahead of time has been extremely helpful to me. In many cases it helps me to make different choices based on how it all looks together. WHen I was using another site It helped me to tweak my menu a bit to increase certain nutrients where I was lacking. I also find it helpful to look up and log potential choices when eating out. Once I see how it in the log I may decide to make a better choice in order to help reach my end goal.

I work nights so it's helpful for me to plan out my day and put it all in before I head to work. It also keeps me on track to kind of plan ahead and pick healthy things, instead of just going "oh, I'll run through a drive thru, or I'll grab a slice of pizza from the place a few doors down."
It's nice to know a general idea of the calories you'll consume too, for snacking purposes, or to see if you need to crank up the exercise that day, depending on your meals.

I frequently do--especially when I am working, then will make any changes at the end of the day

YES the night before! Then I can play w/ the numbers and make sure I don't go over. It takes careful planning to stay w/in 1200 cals.

I do sometimes. Especially when I know that a meal that day is going to be big (like a family cook out or something) that way I'll know what I can have for the other meals to stay within that 1200 cals...also, I'm less likely to grab the extra Dr. Pepper if I know I don't have the extra cals and carbs to spare.

Since I am in contest prep, I add my meals one week in advance. I print it out and post it on my fridge, this allows me to know what macro range I am working with per day.

My meals are usually planned in advance. I tend to eat the same stuff for the vast majority of the week so the MFP log is a bit redundant now, as long as I stick to the right foods for me and only eat when hungry then I'm good.

Yes I pre-log in the week and I usually stay within my calorie allowance as I work out what I can/can't have - I find it really helpful to plan my meals that way.

However at the weekends I log after the event and more-often-than-not I have eaten more than I should and gone over my calories!!

I never log food that I‘ve not eaten, the whole reason to log food is to track it, not to plan it, but keep a track of the amount.
Pre-logging is taking calorie counting to a more extreme level, a level I do not wish to go to.

I eat roughly the same things when I am at work, so I know what kind of numbers I’ll be heading for, but the food tracker is my aid, not my parent, I don’t need its permission to eat an extra slice of ham or a doughnut. 14,000 kcal a week, not daily or by the hour, if I go over one day I either work harder, or eat less the next day. At the end of every week I’m normally left with a couple of thousand calories that I could eat back, but don’t.
