So I've been moving along thinking I was eating 1200 calories per day now for about 12 weeks, counting every meal and snack... I finally got a food scale a couple of weeks ago, before I was going with cups, tablespoons, package info,etc... I started out weighing meats, fruits, veggies, pasta (because I knew the cup thing wasn't working there!), things like that.
This week I started weighing things I normally use a measuring cup or spoon for -yogurt, rice, trail mix, granola, coffee creamer (the one tbsp I allow myself...), peanut butter, fat free caramel apple dip that I eat several nights per week, etc...
My yogurt was pretty darn close, actually a little under most of the time.
My rice had almost an entire serving extra - 32 grams, 45 g is a serving... That is over 100 calories!
My trail mix varied from 20-80 over calories per 1/8 c I was measuring out... And I was sometimes eating a small trail mix snack twice per day at work...
My granola, also pretty darn close - within a gram or so up or down...
I was consuming 10 extra calories per day in coffee creamer, small number until I looked at the fact that I have one cup of coffee every single day...
My peanut butter was very inconsistent - luckily I didn't eat it much...
My caramel apple dip that I rated at around 50 calories based on my tbsp was actually closer to 75 cals...
I've been succeeding - I lost 1.8 pounds since my last official weigh in two weeks ago,17 total. In looking back at the calories I've tracked the last three months I now realize that I lost that weight eating more calories than I thought... So this week I've been eating the 1200 I thought I was eating before because I've weighed out everything, and I worry about slowing my metabolism down and hurting my progress... I'm thinking about moving up to 1300 - my feeling is that it can't hurt me, I've probably been really eating that all along on average and just didn't realize it...
I just had a small trail mix snack at 3:20 and am already hungry again... Could be really hungry, could be stress hungry...

I think you'd be doing fine to just go ahead and adjust your calorie goal number to meet what you were actually getting.
