Frustrated

First: Ignore the "if every day were like today" message you get when you close your diary. (You also don't have to close your diary, it doesn't do anything but post to your newsfeed and show you that BS message.) There were so many more factors that made today like today than how much you ate and how much you moved, which the app cannot know or account for, that any estimate it gives you is essentially worthless.

I'm also a little concerned that you're somehow posting calorie totals that would lead to a loss of 3lb per week if you were a perfect machine in terms of CICO - that's 1500 below your maintenance calories each day, on average. MFP won't give men a calorie goal lower than 1500, and the app won't let you close your diary with less than 1000 calories logged for the day (or it used to do that, I don't close my diary so I don't know). You don't say what kind of exercise you're doing, but unless you're very tall with a very low bodyfat%, your maintenance calories is probably lower than 3500/day. So, I think your numbers are a little out of whack, too - maybe go back and make sure you have your profile filled out correctly, in the units you intended. Go through the guided setup again and tell it you want to lose 1lb per week. Your activity level is meant to be how active you are without counting purposeful exercise; log those 3 workouts each week and eat back at least some of those calories. If you have a desk job, mark yourself Not Very Active, but if you spend a good part of the day on your feet or walking around, put Lightly Active or Active.

Finally, the last thing I would check is how accurate your logging has been. People are, as a species, just shockingly bad at estimating this kind of thing and also really good at eating more calories than we need. It used to be an advantage, before you could drive down the street and just buy 2000 calories for a fistful of dollars (or press some buttons on the magic glowy brick in your pocket and *summon* 2000 calories straight to your house, for a few dollars more). If you aren't at least measuring your servings with cups and spoons, if not weighing them with a food scale, I would start doing that. Mass is always going to be more accurate than volume, and if you're not seeing the results you want, using a food scale is a good way to really dial in the calories-in half of the CICO equation. The other piece of accurate logging is making sure you're picking correct entries from the database. There are a lot of entries that are incorrect or missing information, because the database is largely user-created and things vary over time and from place to place - we're a global community, after all. Always compare what comes up in the database to the label in your hand (for packaged foods) or the USDA SR Legacy food database (for whole foods), even and especially if you use the barcode scanner. The scanner is not downloading any information from the label, it's just searching the database without you having to type anything. Barcodes get reused, and companies change serving sizes or recipes over time, too, so the entry might have been accurate in 2012 but isn't anymore for one reason or another.
