Had my fitbit since Dec. 11. I started on Spartpeople Jan. 11. Bummed that the 2 didn't sync and found myfitnesspal from a facebook friend who said she loves this site. I was very happy to learn that it syncs with fitbit, and I love the app that lets me scan the bar code of the food I am eating and track it. (Cause I am so bad about tracking, lazy mostly) it couldn't be any easier for me! NO MORE EXCUSES!
The question I have is when I work-out should I add it on MFP or Fitbit? I do like to use the timer when I do workout too.

I probably wouldn't eat that adjustment in the morning, well you probably won't need too as it is probably not likely you would go over your base goal with breakfast. :-) MFP recalculates your adjustment every time your fitbit and mfp account sync. I don't think deleting it makes any difference since it recalculates it. It can go up or down depending whether you sustain the activity level mfp bases the adjustment on. Seeing one in the morning just means you were more than sedentary this morning. I think anyone who is getting close or exceeding fitbit goals would most likely end up with a substancial adjustment on mfp with a sedentary setting since the goal of the fitbit targets is to ease us into being active. I take it as a good sign to see one whether or not I choose to eat some or all of those calories.

Remember your fitbit burn is a little similar to the old Police song "every step you take, every move you make". It is possible that you may be a little more active than you give yourself credit for. But be cautious with eating the adjustment calories at first just because they can end up decreasing (and it is a little frustrating to think you are in goal range to look the next day and see you overate a little from those adjustment calories). After a few days you may see what the pattern tends to be for your schedule and activity level.

If your settings are correct on both sites and you aren't logging false activity on fitbit (which can sometimes happen driving, on roller coasters, etc), you should be on the right track.


it was up to 377 by bed time. I honestly was so lazy yesterday lol. I only earn about 270 calories doing 30DS! (which i didn't do yesterday) Fitbit have me down as burning 2300 calories a day, yet MFP have me at around 1950 to maintain my weight, could that be the difference??

Are you set to maintain? Is 1950 the calories you may eat without exercise to maintain? Or is that your "calories burned from normal activity" from the goals page?

Fitbits daily burn will vary by how active you are that day. Seriously my activity level can vary, fitbit has me burning anywhere from 1500 to 2300 depending on how active I am that day. MFP currently has me estimated to burn 1570 without exercise at a lightly active setting. The mfp base does not change according to my activity, if I go under (on a 1500 day) ir is the same and if I go over it is the same. They basically take their estimate of my bmr and multiply it by a certain number (I think something like 1.3 but it is different at the different activity levels). This is really how a lot of books and sites that estimate your daily burn work, they use your profile to estimate your bmr then multiply that by another number according to your activity level.

When I add my mfp base (from the mfp goal page) to my exercise calories (including fitbit adjustment) the number is quite similar to mine on fitbit. (Which makes sense since that is what the fitbit adjustment is doing--giving us more activity calories). There is a small difference, which I think may be just a difference in how the two estimate bmr (not sure though).

Cheryl, I think you would probably be fine only logging whatever you already log. Using the timer doesn't matter, use it if you want. If you do choose to log an activity, the official advice is to log it here and mfp logs it to fitbit. Some people log it at fitbit with no problem and some here with no problem. I log here so the workout is on both my diary here and on fitbit. I don't log every activity though, I don't log walking and often not jogging (unless my heart rate monitor gives me a higher calorie burn that day often they pretty much match though). I use the timer often just because I like seeing the record it makes.

no i'm set to lost 1lb a week, i just changed it to maintain for a minute to see how much it would give me.

yesterday it gave me an extra 600 calories by the end of the day. I did do a lot of walking (around a mall lol) I'm just not sure if i should eat them as I've never had them before, but it makes it look like my net calories is about 7/800 in a day (I'm set to 1420 calories a day)

Why would fitbit log anything when you drive? Your sitting down!


It depends. I don't usually have this problem, but it is a common one. I suspect it may be more common if you wear your fitbit on your hip, but it can happen to those who wear it on their chest as well. Depending on the road your drive or the vehical, there are these vibrations and you are not perfectly still. Sometimes they may mimic the impact you would experience in a step so it credits you with a step. Impact seems to be one of the things the fitbit uses in it's estimate of your steps/activity level/calorie burn. Usually I only see a few extra steps or a few dozen but not enough to really raise the burn. The same thing can happen with other activities that move your body enough such as carnival rides. As mentioned, logging the time as driving can correct this for a bumpy ride/drive.

ETA: for those who don't know. If you have this problem and wish to try logging your driving. Log it on fitbit as that is where it is set up to correct the problem (I don't know whether it corrects floors though, but it should with the calorie burn anyway). Also, your nonfitbit using mfp friends won't be curious why you suddenly consider driving a workout, lol!


I do quite a lot of driving in my job and the change in elevation cause the FB to log them as stairs climbed. So I have to manually log into FB as driving to zero out the stairs. Other than that, it works like a charm!

I was very active while sleeping. How can that be? Has that happened to anyone else?

Mine show that when I have tossed and turned all night. Not sure how that works with you but for me I really have a problem with restless sleeping. It is nothing for me to be up hourly all night.

What do you mean? You received "very active minutes" while sleeping? When you logged a workout, did you accidentally log am instead of pm? That happens a lot. Also, is your time zone correct?

Or do you mean you were surprised by the steps and calorie burn you saw on your fitbit when you woke up?

I went to bed at 10:45. When I synced my FITBIT in the morning and logged my sleep, it said that I was very active between 12:00 am and 12:30. I did do my bike for a little so I went over my 10,000 steps for the day and that was at 10:00. My FB said that I was asleep until 3:45 for a couple of minutes. I was wondering how it shows that I was "active in the hot pink color" if I was sleeping. If I was tossing and turning I would of been in a sweat. Time zones are correct on both sites.
March 26, 2012 12:05 PM
I rechecked my time zone and one has 5:00 and another has 4:00 both Eastern US. I wonder if that was the issue also because I did my bike for 30 mins at 10:00.
March 26, 2012 12:54 PM
Make sure your time zones are correct and match each other. The red in a sleep log isn't the same as "very active" when awake as it is a little more sensitive with sleep to pick up on your tossing and turning. In your settings there is an option for sensitive or normal during sleep tracking. Most people find they have a lot of red (compared to sleep activity levels) when in sensitive mode, I think that is for people who are pretty still when they sleep. Since the fitbit is on your wrist it can pick up a lot of small movements like adjusting your covers, pressing the snooze alarm, etc. Usually when I see long spikes of red during sleep it is when I get up to use the rest room. I once did have some mysterious night activity, but at the time I was not wearing my fitbit and have no idea whether something was vibrating or something where it was (it was sitting in a medicine cabinet as at that time I didn't sleep with it).

Is there an option for daylight savings time on one so they match?
March 26, 2012 1:09 PM
Actually I just checked it again and it says that it was active on the regular scale and not on the sleep scale. There is no other time zone to change to on either site.
March 26, 2012 3:18 PM
I think I've worked out why fitbit gives me so many more calories. Here on MFP to lose 1lb a week my sedentary calorie allowance is 1420, yet on fitbit to lose 500g a week (just over 1lb) its 1739 before any activity (which fits with the numbers on the fat2fit website too) Thats over 300 calorie difference, which is about the amount fitbit give me in their adjustment by the end of the day.

Ok. I had that once last year for a mysterious reason when I wasn't wearing the fitbit and it hadn't happened since so it could just be something weird that happened (there is a thread on this forum about fitbit poltergeists). But one thing to watch for, the suggestion to wear it on your non-dominant wrist for sleep. That seems to work fine for sleep for a lot of people, but it will sometimes pick up fairly small movements. I had steps once reading in bed from turning the page of a book (so I now just put it on my wrist just before sleeping not if I am reading in bed. It could be that you make large movements in your sleep. Did you get up at all? Hopefully it is just something weird that happened the once. Are your time zones correct now? I don't think it will correct past activity, but it may help with the future.

ETA: you might be able to get rid of that activity if you manually log that half hour as sleeping in the activity log if you want to try to correct your calorie burn. If that doesn't work, try driving (driving should get rid of the steps but the calorie burn would be too high compared to sleeping).

Thanks so much for all of your help. I am only counting the calorie burn that I entered into MFP. I wanted to just use the FB this week, but not today, I will see what happens tonight. Thanks again. smile
March 26, 2012 6:34 PM
I wasn't able to change the time zone thing. There were no other choices on either site.
March 26, 2012 9:07 PM
To change your time zone on fitbit, look on your dash for "profile settings" (on your right under your profile picture. It is towards the bottom of the "edit profile" page.

On mfp, go to settings then choose the option "change time zone". It looks like neither asks about daylight savings, but you should be able to choose the correct one.

Interesting that it logs hills, but not the 100 steps ups I do at the gym.

It's based on elevation. You actually have to go up a flight of stairs for it to count it. Or if you're driving and go over an over-pass, it can count it as stairs because of the elevation...which is why I have to log driving to remove the extra "stairs" that I did not climb. So no it will not count stair-stepping on a machine as climbing stairs...there is no change in elevation.
