So, I understand how the link between Fitbit and MFP works. If Fitbit says I burned 3000 calories, but MFP says I was supposed to burn 2,500, I earn 500 extra calories.

Right now, I have MFP set to maintain weight. I haven't been wearing my Fibit. MFP says I need to eat 2060 calories to maintain my weight if I'm sedentary. Fitbit said I burned 2,288 calories yesterday with it not being worn. Based on howt the link between MFP and Fitbit works, I should have earned LEAST 200 extra calories.

Why is this? Shouldn't my calorie goal at LEAST be 2,200 calories since Fitbit says I burn that if I do NO activity all day?

    There are a few calculators out there for TDEE (what you burn on a daily basis). MFP and Fitbit sound like they use different ones. Basically you have to do trial and error to see what your actual TDEE is. Averaging them is a good place to start. You can also check out this page for some more calculators. http://scoobysworkshop.com/accurate-calorie-calculator/

    When's the last time you changed your weight on your Fitbit profile?

    Is your Fitbit set to estimate your calorie burn when not worn? If so, then the 2200 isn't Fitbit's BMR estimate for you, it's its TDEE estimate.

    Also, I imagine if MFP thinks you burn 2500 and your Fitbit said you burned 2200 yesterday, there won't be a positive Fitbit adjustment since 2200<2500. But I don't use MFP's plan so I could be wrong there.

    I'm not even sure that a 'calorie estimation' day (Fitbit not worn) triggers a MFP calorie adjustment at all. Fitbit says it doesn't count those days into your averages for their site.
