Hi, I've tried searching for this answer but can't find it!!! I got the FitBit app for my iPhone yesterday, it works off the motion sensors in the phone so I just stick it in my pocket and off I go. The thing is the calories on FitBit and MFP are different so which should I go by? MFP Is telling me I have 100+ and FitBit is telling me I'm 35 over - any help appreciated

    Since 70 or so calories won't do much in the way of a big change, it doesn't really matter which you choose. But I use Fitbit and because I log food through MFP, I go with that number.

    Same here. I only add foods and exercise through MFP. Do you have the negative calories box checked? It takes a few days or a week before it get a base to work from, so if you do, give it time to gather information.

    You might want to check if you have them set up differently. I only use the calories burned part of the fitbit which syncs with MFP, and I track the food here. (I also use the step, stairs and sleep trackers as encouragement, and the silent alarm is awesome).

    You shouldn't be tracking on FitBit's website if you are also tracking here - according to the MFP guide you should log everything here and MFP will use the calorie data from your FitBit.

    Hope that is helpful.

    Ok I'm even more confused now!!! I haven't eaten anything else but I'm now more over my calories?!? Also FitBit has a goal of 1200 for me and MFP has 1430 - how do I change the FitBit to make it the same as MFP?

    Have you synced MFP and fitbit lately? My numbers are usually a few calories off between the 2 apps... I don't worry about it. I just eat according to MFP. I only use fitbit for steps and calories burned. It's all estimated anyway, neither is precise.

    The flex is really accurate for me. And you can change it in the settings, they won't be spot on the same there might be a 50ish calorie difference in what they say you need,

    Okay, so I was using just the MFP app for a couple weeks, and lost weight really fast--like 4 lbs a week fast, yes probably too fast. I was sticking to around 1440 calories a day during this time and was pretty active, exercising around 4x/week. I got the Fitbit Flex, synced it and of course saw that I was burning a lot more calories through daily activity and exercise than I thought. I started adding the calories that MFP and Fitbit calculated that I could(varied, but around 1600-1800), and pretty much stopped losing weight for the next two weeks. Very frustrating. Started just focusing on the MFP's goal for me to lose 1 lb/week, which is 1370 calories a day and not looking at what the FitBit calories add. Is this right? I feel like the calories calculations for both at least for me are not accurate at all for weight loss. Has anyone else experienced this?

    You probably have calorie estimation turned on.
    Theres your calories burned, which shows you by minute - hour how many you've burned real time -- then there's your food app which estimates for your entire day how much it thinks youre going to burn based on your trends of the week.
    Therefore, if you move more it gives you more calories, and the less you move the more it goes down to change its estimations to accommodate actual burns for the day.

    Everybody's different, and weight loss takes a whole lot of trial & error to find what works for you.

    Enable negative calorie adjustments:

    Adjust your activity level:

    Enable/disable Fitbit's calorie estimation:
    http://www.fitbit.com/user/profile/edit

    Fitbit pro-rates your calories by time of day (and goes way below 1,200 calories), so I ignore it & follow MFP's calorie goal.

    The calorie estimation changes throughout the day, but gets more accurate with time. I log my food and exercise on MFP and allow negative changes. at the end of the day it'll fall back into place most of the time.

    MFP calculates your calorie burn really approximately, fitbit isnt always on point but it's a lot more accurate.

    I have the Fitbit Flex, I log my food in MFP and log my activities in Fitbit, this gives MFP the additional calorie deficit. The calories burned are a lot lower this way and and it makes me work harder I think to burn more. Not sure if this is correct but I am still losing weight BIG SMILE.

    This is absolutely correct. Do not log step based activity. Log non-step workouts in Fitbit or MFP. I, too, find Fitbit's burns to be way more accurate than MFP's one-size-fits-all guesstimates.

    That is what I was about to add in there that I am going to be doing stretches and the like this morning and will log that directly into MFP. Thank you very much for the clarification

    Thanks for all the replies :) I think I have my settings sorted now. My next question is when I set up MFP I included 2x 45 minute MMA class, do I add this manually as my FitBit is tracked on my phone which I won't have in training with me. Thanks again

    Unless they've recently changed something, the planned exercise you enter at http://www.myfitnesspal.com/account/change_goals_guided has no effect on your calorie goal. I've never understood why it's there.

    Do not log step based activity. Log non-step workouts any time after you've completed them either in Fitbit or in MFP.

    Don't know whether to invest in a Fit bit. Seems to cause a lot of confusion when used in conjunction with MFP

    I got my Fitbit last week and find it is really motivating me! I log my food on MFP, but let Fitbit be my guide. As many have said already, the Fitbit is more accurate in terms of calorie burn as MFP does use a more one size fits all approach. Additionally, I've got several friends with Fitbit that go to nutritionists. They did the math and found the Fitbit to be fairly accurate.

    I follow the Fitbit. It prompts me to keep about a 500 calorie deficit over the course of the day, so I find it easier to follow. Plus, seeing the number of steps I've done vs my goal REALLY gets me motivated! I just can't bear to lose, so I HAVE to hit my goal for steps. :) Thus, it makes me move a little more and eat a little less.

    Bottom line, love my Fitbit. I think the thing to recall is that there is no device/program that will be exact for all people. I say give it a try, you can get the Fitbit Zip for about $45 on amazon right now and they have a lovely return program if you decide its not for you.

    Just started back up with MFP and also purchased a fitbit One and Aria scale. The only reason I'm still using MFP is the food logging and recipe integration can't be beat. I log my food in MFP and everything else happens in Fitbit. Just ignore what MFP is telling you and trust the Fitbit guide, though you might want to get an actual Fitbit one/flex as it'll be more accurate and you can wear it in your MMA classes.

    Highly recommend them. I log my food in MFP and it syncs with my fitbit one which gives me my step calories. Easy Peasy. I don't log anything into Fitbit, just let it do it's thing feeding MFP.

    So you don't actually have a FitBit Flex, Force, One, etc, you are just using your phone? I don't think it is actually tracking your movements because FitBit is not set up for that, that I'm aware of anyways. The app for the iPhone is so you can sync your FitBit from your phone and not use the computer. Is it actually showing how many steps you have taken through the day on FitBit?

    Edit - Nevermind! I didn't realize they came out with this. I wonder how accurate it is though.

    Lol!!! It tracks all my steps - just finding I forget to keep my phone with me all the time if I'm wearing something without pockets so looking at getting a flex now :)

    If your fitbit is saying 1200 cal than go in to MFP and set it to 1200 cal ...but I can't see that as 1200 is the lowest cal per day you should go.

    not sure of your measurements or weight age etc but I use these website and it has helped me
