    Have had both, the are pretty similar. No difference in accuracy that I could tell. Fitbit is easier to hide. The company pissed me off bc they only offered me a slight discount on a new fitbit when it died bc I sweated too much on it even though it was less then a year old. WTF!? A fitness item u can't sweat on!? They very sweetly (NOT!) told me they have a new fitbit I should consider buying that is water/sweat resistant. Relatively new to bodymedia. Refused to get another fitbit after that wonderful interaction w customer service. I haven't had issues so don't know if their service is any better.

    I hope it's okay to comment on a different one that I got as I have never tried either of those. Like you, I had gotten a Polar and the one I had gotten was about $200. After the battery ran out, I had a horrible time getting it to work again without sending it off to Polar. I recently got a HRM called ePulse2 and so far I really like it. I don't wear it all day, but just when I work out. I wore it here to work (I work in a medical clinic) and put a pulse ox on my finger to see if the epulse was matching up with our medical ones. It matched exactly which I was happy with. I have a mechanical aortic heart valve so it's good for me to keep good track of my HR while exercising. I can also see calories burned, along with it let me set my stride and use it as a pedometer when I walk in the evenings. It is worn on the upper forearm near the elbow. It cost about $85 off Amazon.

    I have the BodyMedia LINK armband.

    When I was wearing it religiously (we started remodeling and I misplaced the power cord, but found it again!) i totally forgot I had it on....even hopped in the shower with in on (thankfully didn't get it too wet, still works!)

    It's comfortable. I've never gotten 'dimples' or a rash from it.
    (you know how continuous and hard you have to press on skin/muscles to get a permanent 'dent'? Very hard for a long time, you aren't supposed to wear the band super tight.)

    I love that it syncs with my smartphone so I can check progress at will, and with the new update, the data from the armband can be synced to the BodyMedia website via upload through the smartphone app. I also like that it tracks sleep and sleep efficiency. That's one area I've been trying to work on is being more mindful of getting a proper sleep amount.

    I had not heard of the Bodymedia until this post but that is cool that is measure sleep and sleep efficiency!! Sleep IS very important and one thing I need to get more of also. I typically get about 5 hours a night and feel tired much of the time.

    Love my fitbit. As a vain female, I wouldn't consider anything on my arm.

    I have a fitbit and linked it to Myfitnesspal. if i stick to the calorie goals that are produced with the conjunction of fitbit and myfitnesspal, i lose 2 lbs a week just like it says i will.

    I was honest about my activity level and would have altered it if things were not corelating. The fitbit hangs from a necklace on a carabiner. Cant lose it, not in the way at all.... I am not going to walk around with an arm band. I dont care about what others think either, but having an armband on 24/7 does not appeal to me.

    Fitbit has no subscription (there is a premium option but its pointless for most) and i forget i have it.

    I can vouch for accuracy. Johnythans experience is the same exact one as mine. it has been a steady and measured weight loss. I dont even have to exercise much unless i want to fit some indulgences in.

    Here is my two cents...

    Let me first say I am purchasing a FITBIT this weekend. I currently have BodyMedia Link.

    I also use (or have used the following):
    Garmin 310 XT
    Garmin 910 XT
    Polar HRM (not sure which)
    Garmin Edge 500 (cycling only)
    Garmin Edge 810 (cycling only)

    So to help put all this together, for about 2 weeks during my workouts (and only my workouts - I race triathlons and wil lrace my 2nd Ironman this year in Oct.)

    I found the following:
    Garmin 310 has the lowest calories burned
    Polar has the highest calories burned - sometimes laughable like almost double the others!
    BodyMedia Falls in the middle, about 10 to 15% more than Garmin

    Even between the Garmin devices, there is variation due to the age of the algorithms used. The 910 and 810 are the newest and use technology from FirstBeat (you can research their studies/white papers online if you are a nerd like me).

    When using the 910xt, the Calorie burn is higher than the 310xt (both are triathlon gps hrm). The 910xt is lower on the calorie burn than BodyMedia and still WAY different than Polar. Essentially, I felt my Polar was way off and quite honestly, useless for calorie burn. Don't get me wrong, for heart rate training (Google it), it would be more than a great entry point just ignore the calories burned.

    Because I am vain, I have worn the body media both on my arm and around my ankle - essentially the same results for the same workouts (bike rides) Maybe 20-50 calorie difference, which over a 3 -5 hour ride is within the margin of error given outdoor temp variations, recovery, existing fatigue, etc.

    Now when I cycle, because I usually wear a tank top, I wear the bodymedia around my ankle (doesn't look as dorky and it avoids a tan line)

    To give you an idea of the difference between Garmin and BodyMedia

    6 hour century ride (lower intensity):
    Garmin 2100 calories roughly
    Body Media 2300 calories

    2 hour cycling:
    Garmin: 525
    Body Media: 640

    Brick workout (bike and run on same day, in succession):
    235 Minutes cycling + 150 minute Run
    Garmin: 2995 cals
    Body Media: 3592 cals

    FYI, using various Garmin GPS devices, the last 365 days I have logged over 3300 miles cycling, and 700 miles running. 2900 of those miles have been since I have purchased, and usually worn, the BodyMedia. Garmin has me listed as (for only the workouts) burning over 133,000 calories. BodyMedia only lets me report the last 28 days.

    So the Grand Question: Which is more accurate? To be honest, I think the body media is more accurate for the 'daily use' as it accounts for 'all the other daily stuff' we do, but I feel it overestimates during 'real' workouts. So, it's almost a wash if your workouts are an hour or so, or less. I ran a slight deficit the month of July, according to Body Media. I did want to run a caloric deficit so I could get 'Lean Muscle' for racing. I lost about 2 lbs (which I didn't log on MFP). On average, I ran a deficit of 247 calories for 28 days. On longer workouts, I usually ignore the BodyMedia Adjustment or delete it, as feel it is high. So I use a mix that seems to work well for my goals. As with MFP, BodyMedia, Garmin, Polar are all just pieces of the puzzle. And it's a different puzzle each day, for each person.

    Sidenote: there is a lot more to consider, point out, contemplate, debate, etc., but its becoming a thesis... I pointed out what I feel is the meat of the bones, but PLEASE take it with a grain of salt. There was no real 'Scientific Method' applied.

    Additionally, when I get the FITBIT, I will revisit my post with what find. One thing I like, and the reason I am looking at the FITBIT, is I can wear it while I shower. I sometimes forget to put the BodyMedia back on after showering. Now if only I can find one I can swim in (it doesn't even need to take measurements lol).

    Hope this helps!

    I have both. I find my BMF gives me a regular daily calorie burn of 200 Cals above that of my Fitbit.

    I started using FITBIT, and also am wearing BodyMedia.

    Things I need to point out about Body Media - It DOES NOT leave any lasting impressions/marks on the skin. I snickered when I read that! Who ever posted that is ill informed. After you remove it, yes, there is a mark on you, sorta like when you take off tighter socks, there are indents. In an hour, the mark is gone. I have been using BodyMedia since January and still don't have any deformities. BodyMedia uses Heart Rate, Movement, and Body Temp (which I don't nec. agree with) to determine calories and if you are 'vigorously' working out.

    I don't yet know how FITBIT Flex works, but the no where in the literature does it say it uses heart rate. Heart rate is the second best method for determine calories burned (distant second from the best way - wearing the mask, measuring CO2 output, etc, but still second). The SLEEP mode is aweful. Flex, you need to tap the thing to tell it you are going to sleep, and tap it when you wake up. Body Media knows when you are lying down, as well as when you are lying down, awake, or lying down asleep. The problem is it cannot differentiate when I am lying on the couch watching TV, or lying in bed, trying to fall asleep.

    After a long, cold, wet bicycling ride, Body Media had me burning 1265 calories. Garmin had me burning 1010. Fitbit had me at 320. Its new to me, so I will check into this.

    So far:
    2 Days in: BodyMedia 2, Fitbit 0

    Tell all the people in this thread (and others on this site and other sites) that they don't actually have any indentations or impressions on their arms. They're just ill-informed.

    You are ill-informed. BodyMedia products do not measure or use heart rate. The armband measures movement (steps), sweat, and temperature.

    Right now I'm using the Fitbit One, though I continue to research other options (especially new ones). For me the advantage of the Fitbit has been that it is a great choice for just wearing at all times. While there are other options that add interesting data, or accuracy, during workouts the Fitbit lets me track activity during real life without getting in the way of real life.

    So far, for me, the problem with the Bodymedia Fit is that its too intrusive for constant wear yet doesn't add enough data to make the inconvenience worthwhile. If they come out with a version that does measure heart rate, well then I'd reconsider it.

    The people prob. have the thing on too tight! Then they piss and moan because there is a mark on their arm for an hour or so! lol. It's comical. Sort of like wearing boxer briefs with elastic that bunches in an area - there is a mark for a spell then its gone! :)

    As I mentioned, I have worn the BodyMedia for over 6 months, removing to shower and swim. No lasting marks! I also move it to my ankle when I am out in the sun because I am vein and don't even want tan lines.

    I was wrong about the Body Media, you are correct. It doesn't use heart rate. I thought I read it did several months ago. It should since it has the metal plates already there. I assumed it did as the calories were fairly close to my HRM.

    Give me a two weeks (I have a recovery week for workouts - low intensity / low volume, followed by a high volume / high intensity week) and I can definitively tell you which I think is better since I am currently wearing them both!

    At the moment, my first pick is still any Garmin HRM! I started using FITBIT, and also am wearing BodyMedia.

    Another FYI - The crude Activity Calculators on FITBIT and BodyMedia can be WAY off. FITBIT says for my Bike ride, I burned roughly 2950 calories and BodyMedia's calculator had me burn 3050.

    Fitbit devices measure movement and only work well for activities involving stepping. On a bicycle, your torso doesn't move so the Fitbit doesn't record much activity.

    I have a BodyMedia Link and I love it! Very accurate. I dont like the armband because if you wear it long enough it leaves an indentation in your muscle that takes a while to go away, and it screams "I'M ON A DIET!" I have since learned to wear it on the inside of my bra strap under my arm next to my rib cage and it does just fine there. No one knows I am wearing it, no indentaion and I still get my info. The only time I use the armband is when I sleep. It is a great device to keep you on track and gives great insights.

    I am picking June because Ohio sorta had a cool July.

    June 28, I rode 6 hours, 12 minutes. Fairly low intensity ride, started the ride at roughly 1:30 so I was training in the heat of the day. Garmin had my calories at 2807. Body Media had my calories (going in and zeroing in on the time of my workout): 3457 calories.

    June 18, 1 hour, easy ride: Garmin: 504 cal, BodyMedia 518

    I love the fact it knows when I am just lying down, and when I am actually asleep. No tapping, no interaction from me. It even logs if I have a nap during the day!

    I like the idea of the fitbit flex. It's small, can shower with it, doesn't scream diet lol. People around me just assume the BodyMedia is another HRM since we all wear them. That's why I am putting it through the paces versus what I currently use...

    Almost every time this question comes up (and it's fairly often), it seems most people agree that Fitbit is the way to go. I have a Fitbit One (had it almost a year) and I love it!

    When I see this question, I often refer people to this article that I stumbled across earlier this year.

    Just got my BodyMedia Link late last week. My wife has had her's since May. She loves hers, and I've yet to find anything to not like.
    My normal wear at work is business casual. No one has noticed this thing on my arm, but I have been showing it to lots of people, so maybe it is that the people who would have noticed it already had me showing it to them.
    Yes, it leaves an indent. About as much of one as my socks and underwear do when I take them off at the end of the day. Since I don't often run around with my shirt and it both off I don't see it as a problem. Not like the people in my shower are going to be asking what I did to my arm. Maybe if I was going to wear something that left my arms bare to something fancy enough that I wouldn't want people to see it I'd care more about it, but I don't see myself wearing a sleeveless dress anytime soon, so I don't see it as a problem.
    Very impressed with how quickly I stopped noticing I was wearing it.
    It doesn't collect hear rate info, but can link to a HRM and show you that info on the website.

    I was actually coming in here to see if anyone had some insight into adjusting to this new combo way of tracking net cals it is making me deal with. I'll admit I am not making it easy on myself, as the first full day I had it I ran my first measured 5k, and then on Sunday walked 6.5 miles, so I have several big cal burns messing up my baseline.

    it screams "I'M ON A DIET!"
    First time I saw one I assumed it was a mp3 player, as it didn't look like a phone.
    They were walking around in the grocery store wearing workout clothes so maybe that is why I didn't think anything about it.
    Definitely didn't make me think diet, as they looked more like someone who spends most of their time in a gym.
    Come to think of it, I've got one, and seeing as I am trying to eat at a balance, so I can lose this last bit of fat, and put on some muscle to replace it, I don't think mine makes anyone think I am on a diet.

    I am curious what data it used to compute that, since the device would have measured next to no movement on your arm.
    From their website: "BodyMedia FIT is worn directly on your arm. Its patented sensors detect skin temperature, heat flux and motion, so it knows what you're doing, when you're doing it and even the intensity of your effort."

    My words:
    It takes some 5000 readings per second of the electricity of your skin, body temp, how fast you are getting rid of that heat, and the motion of your body. This means even if your arm and upper body are perfectly still and restrained, it is still going to be able to tell that you are working hard to do 3 sets of 20 reps of 500lb leg presses. It has no clue what you are doing, but it knows you are working hard. This is why it can tell the difference between you running up 15 flights of stairs, and you running up the same flights wearing a 120lbs in a backpack. It can also tell the difference between you laying in bed wishing you were asleep, and you being asleep.
    This is also why it is a FDA-registered medical device.

    I know what sensors it has. That doesn't tell us how they are computing the calorie burn. Presumably they're doing it based solely on heat flux and sweat, but there are so many situations where that could lead to incredibly misleading calculations that I don't think that's all they're doing.

    BTW, the FDA registration doesn't mean anything in terms of accuracy or anything like that. It means they paid the FDA to register the device as a Class II device for purposes of safety. The FDA is reasonably assured by BodyMedia and BodyMedia's registration fee that the device won't electrocute you, in other words.

    I know what sensors it has. That doesn't tell us how they are computing the calorie burn. Presumably they're doing it based solely on heat flux and sweat, but there are so many situations where that could lead to incredibly misleading calculations that I don't think that's all they're doing.
    When I was in the hospital all they did was attach two electrodes to me to get the readings they needed. There are many situations where that could lead to incredibly misleading calculations...but since 99% of the time it works, they continue to use it.
    This is kind of the same thing.
    All I know is that it pinpoints exactly when in my day I start walking, and when I start to run, when I hit the hill, and when I start coming down the other side, and when I am lifting weights, when I am laying down watching tv, and when I drift off to asleep. It can tell the difference between when I am giving it 110%, and when I am phoning it in. Seems good enough to me.

    And it is way better than the current version of saying I ran 2 miles in 15 minutes and getting a calorie burn out of that, seeing as there is nothing in that to say if it was done on a high school track, or going up Pike's Peak.

    I have had a bodymedia link since last OCtober, when I was wearing it and tracking my calories religiously, I lost 10lbs in less than a month by eating under my bodymedia calorie burn for the day.. It really worked for me...and then i stopped! I disliked that it is noticeable so I recently bought the FITBIT 1, and now I"m doing a little research by using both to see which one is most accurate.
    So far I have noticed that the fit bit gives me less of a calorie burn and bodymedia is giving me more steps, which could be from when i'm driving in my car. So far, I'd say I prefer bodymedia because I like that it gives in depth details about sleep and calorie burn and the calorie burn readout that it gives me seems to be accurate since I am losing weight. I decided that if I have a dress or an outfit that I don't want people to notice it, I'll just wear my fitbit for the day. I can also say that bodymedia gave me no "dimples" or indentations on my arm. Maybe if that happens the strap is too tight to your skin.. you don't wanna cut off your blood circulation.

    No one is mentioning the monthly fee you have to pay for Body Media. I deactivated my account last year and at that time it was $7.95 a month! Fit Bit is free so that's what I am asking for for Christmas. I liked the Body Media but I can't justify the cost.

    ^ This. Also the thing about wearing the Bodymedia "Screams you're on a diet"- I would also agree. I just personally like that stuff hidden from the world, but some people don't mind.

    I have both. I wear them at the same time, because I just got a fitbit one so I wanted to see how accurate it is before dumping the hugely ugly and annoyingly visible (to me) Bodymedia device. Fitbit usually calculates that I burn about 200 fewer calories per day (on average) than the Bodymedia records which doesn't bother me. I'm sure the Bodymedia is more accurate there, but it doesn't bother me to have that small discrepancy. They both calculate the same number of steps, almost exactly. And Fitbit is easier to wear, smaller, and has no monthly fee. So I'm dumping the $8/month fee and going with fitbit. Personal choice.

    Ditto that!
    That doesn't tell us how they (BMF) are computing the calorie burn. Presumably they're doing it based solely on heat flux and sweat, but there are so many situations where that could lead to incredibly misleading calculations that I don't think that's all they're doing.

    I'm pretty sure most of the BMF data is from the accelerometer, just like the Fitbit's is. If anything, I bet the skin data is used mostly to determine sleep. And to make people feel like they have more technology on than you'd find in a Wii remote.
