    It's 11:58pm and mfp tells me I have 430 cals left and Fitbit tells me I have 250 left. I choose to always go by Fitbit. I have lost 13lbs in 35 days so I am sticking to it. I think I would eat too much otherwise .

    Fitbit does not include your exercise cals in your remaining cals for the day whereas MFP does from what I can see?
    also, calories are based on what actual cals you have burnt so far whereas MFP takes in a projected tdee when adjusting your cals.

    @becalee26 - Have you updated your calorie goal on MFP since you lost weight?

    Also, if your at 1200 calories, then your deficit might not actually be as high as you picked.

    For example, if I set mine to 2 lbs per week:

    MFP would say I could eat 1200 calories per day. This however wouldn't give me a 1000 calorie deficit. My deficit would actually be 648 because MFP thinks that I will burn 1870 in a day and won't let me go below 1200 calories. Fitbit doesn't care if my goal is below 1200 though, so I will be in a constant 1000 calorie deficit on their food plan. I think Fitbit probably hopes that people will see a really low calorie goal and get off their butt so that they can eat more.

    So the adjustment I get from Fitbit on MFP will be to keep me at a 648 calorie deficit. Fitbit, on the other hand, will still be giving me a 1000 calorie deficit on their food plan. So MFP would allow me to eat 352 calories more than Fitbit would say I could.
