Next day Fitbit flex frustrations.

Why is it that in the evening fitbit will tell me that i am within my goals and that i have 300 calories left in my budget, so I eat a snack thats 100 calories and go to bed thinking I did great and I was 200 under my goal, and then when i wake up in the morning I look at the previous day and it tells me i ate 300 calories too much! So annoying!

When you check it in the evening, you might make sure that MFP has the latest info from Fitbit. Go to your exercise tab (in the web app) and click on the little 'i' next to the Fitbit calorie adjustment and look at the last MFP-Fitbit sync time. If it isn't quite recent, then the estimate of how many calories you have left will be off. I think you can force (or maybe I should say "encourage") the apps to communicate by entering some data that would be exchanged (food or exercise). Just be sure to undo what you entered so you don't have bogus data messing things up. (Also, be sure your Fitbit has synced recently.) I haven't had this problem - mine seem to stay in pretty close sync - but that's what I would try if I needed to get MFP to be updated with Fitbit's data.

If the data is recent, then maybe some setting is messed up. My "calories remaining" definitely go down when I am not active (for instance, when I'm asleep), but there is no way they could go down by 500 between when I go to bed and midnight.

If your MFP activity level is higher than sedentary, and your last sync and eating goal is earlier in evening, then you can get that effect.

Or if you Fitbit is set to Personalized daily burn, but you don't sync your device in the evening, it thinks you have burned more and reports that to MFP.
But next morning upon new sync, the fresh info comes in, new math, same effect.
