    Everyone's different, but my FitBit is extremely accurate for me. I've had my metabolism tested professionally (participated in a University study) and my FitBit readings are very, very close.

    I had a fitbit charge hr for a while but got rid of it as it was way off of what Runkeeper or treadmills were showing for calorie burn

    Was the Fitbit higher or lower than the treadmill?

    Could the issue be that a Fitbit calorie burn is all inclusive, bmr+exercise.

    While a treadmill or run keeper is just exercise?

    I don't know, just seems odd to trust a treadmill etc over a Fitbit.
    I've also found the calorie burn from intentional exercise to be suspect.
    As an example, a few months ago I compared calories burned according to my treadmill and what my Fitbit showed. Keep in mind, I'm 5'8" 125 lbs. The treadmill showed just under 150 calories for 40 minutes of walking at an average speed of 3.3 mph with a slight incline. In that same time period, my Fitbit showed about 275 calories burned.

    According to my Fibit, I burned 1,097 cals yesterday running ten miles and taking over 20k steps. But that is VERY out of the norm for me.

    Also Fitbit gives you your TDEE, the only way to figure out how many calories you burned through exercise comes from synching with the MFP app.

    My daily burn is 2800 cals! When I do NOTHING. I think how much you burn daily is dependent on your current weight and activity level, not JUST activity level.

    Same here :)

    When I'm losing weight, the rate seems to match up properly so I assume the numbers are at least close to correct

    The Fitbit was way out, quite a bit higher
    The treadmills I use have an account sign in and I have my height/weight set up for it and it's usually a pretty close match on a 10km run for Runkeeper, never more than 150 cal out.
    The fitbit was almost doubling what I normally got, it was only ever switched on for running and I setup the online dashboard to only show and use exercise.

    A treadmill would be much more trustworthy than gps or fitbit because it's a constant calibrated machine free of outside influence, boring as hell, but constant.
    Gps & activity trackers can all be affected by outside influences, headwind (not included), bad satellite tracking, extra bounce from rough ground or arm movement, various different reasons

    Well now I'm curious about my daily 'living' burn. I had always assumed it was something like 1600 since that's what MFP had told me to eat to maintain my weight. Putting my info in at the site posted earlier in this thread gave me a number of 1975 kcals/day.

    I wouldn't say no if you're eating that much and not putting on weight. I can eat about 3800 calories a day and not gain weight.

    I find my Fitbit to be fairly accurate, I used it when losing weight and am now maintaining eating all the calories it gives me.

    For reference I'm 5'2, 121 lbs, age 41 and have a desk job but I average 14k steps a day. My average burn is 2200 cals.

    Remember the fitbit BMR is constantly running. To make it math simple, say your BMR is 2400 calories per day, or 100 calories per hour.

    Your treadmill estimates 200 for one hour of walking, your fitbit shows 300 for the same period. It isn't that either is "off", it is simply interpreted differently.

    The sync with MFP, only shows 200 of exercise.

    Obviously, the actual numbers aren't that perfect, but the above is just for illustration. I use my fitbit calories, but don't add in any other exercise, and have my settings at sedentary.

    I used to think my fitbit was horribly inaccurate. I'm 5'1, 34 years old and at the time was 128lbs. The second day I had it it said I burned over 2500 calories. My average burn was 2300 to 2800 depending on how many steps I took.

    I didn't believe it so I purposely ate 200 to 300 less than MFP told me to. And I did it for 8 weeks. During that period I lost 11.8lbs. Instead of 1lb per week like I intended to lose I was losing 1.45lb per week. So my deficit was closer to 750 than 500.

    Now I'm 113lbs and my daily average is a little lower....more like 2100 to 2600. Average is around 2300.

    I guess I'm just more active than I thought I was. I take 15000 to 25000 steps per day.

    The 2000 calories that the government use to base there recommendations on was established by a survey in which people stated what they THOUGHT they were consuming, however when scientists discovered using doubley labbeled water to fugure out the true calorie needs it turns out that women in actuality burn around 2400 calories a day and men 2700.

    According to my iWatch, I burn around 1700 a day with 12k-14k steps a day. I've always thought this was off, but I guess I'd rather underestimate than overestimate.

    I have a Fitbit One, it says I burn between 2400-2700 on my normal days. Seems about right. My friend has the One also, she was having problems attaching it where they suggested and it ends up she put it on a hairband on her wrist....I tried that because she was always getting a ton of calories burned. Wearing it on my wrist for a couple of days, I was burning 3200-3500 a day for the same activity. So, I hope the different styles are calibrated differently for where you are supposed to where them. I mean I would love to think that I burn over 3000 calories every day, but I am pretty sure that isn't right.

    Yesterday was the slackest day ever for me, I spent most of the afternoon on the couch and went to bed at 7pm. I still burned 2100. 5"8 150lbs, age 43
