I ignore the messages saying I need to increase my calorie intake. I do well when I stick real close to what Fitbit recommends since it seems to be take into account my BMR, but I keep inputting my food on Spark since it has the better database and all of my groupings. It seems to be a good guideline. Since I got my Fitbit at the end of Oct, 2012. I've lost 10 lbs. Not bad, especially with the holidays during that period and a 5-day cruise I went on. It has been so helpful at keeping me motivated and aware of just how much time in the day I sit around. Shocking really. Not something you really see with just a regular pedometer.

I'm driving myself crazy trying to figure this out and adjust. According to FB, I should have lost at least 3 lbs (figured a 4,000 cal deficit per pound) ... yet I lost .5/lb. Even though I increased my activity, caloric intake one week to the high end, another week to the low end of the range, the 3rd week up and down ....

So for me I am just using it to move more as it isn't helping with my weight loss yet.

I find my fitbit calorie burn estimate seems accurate most of the time as far as I can tell. By as far as I can tell, I mean:
*I have been wearing one for about three years. When I accurately track my food, my weight goes up or down or maintains following what my fitbit would predict. For three months last year I kept a spreadsheet of my daily weight, bodyfat estimate and calorie intake and fitbit estimate and fitbit deficit. It seemed on average I lost one pound for a 4,000 calorie fitbit deficit (sometimes a little more or less). So I figured it is either on the slightly high side of accurate, my food logging is flawed or my heart rate monitor slightly overestiamtes. (I used the calorie burn from my heart rate monitor for some activities including strength training and yoga--even though they are not the type of activities that hrm's are calibrated to estiamte).
*For a lot of step based aerobic exercise, my fitbit and heart rate monitor agree or are within 50 calories. This includes (for me) jogging, jump roping, cardio kickboxing, aerobic drills exercises (like jumping jacks, football runs, etc), and some dance. There are some activities where they disagree for me. They are all just estiamtes not direct measures though.
*Since I calibrated my stride lengths for running and walking my distance and speed information usually seems accurate or close compared to when I know the actual distance.
*The calorie burn range fitbit gives me tends to be around 1600 if I am pretty sedentary (around 4,000 steps) and 2200 or so if very active (moving most of the day, exercising 1-2 hours. I like to exercise so sometimes do this when time and energy allows). This is actually pretty inline with what I get when I use a formula that estimates my bmr then uses an activity multiplier. These calculators estimate that I should burn between 1487 (sedentary) to 2354 ("extra active" i.e. physical job + exercise). The only times I approached the 2354 were rare days when I acheived over 25,000 steps and logged some activity from my heart rate monitor in addition to fitbit estimates (but this was at a slightly higher weight). I am probably not quite as sedentary as the estimate (they multiplied my bmr by 1.2) nor am I quite as active as the 2354, so my observed fitbit range of 1600 - 2200 doesn't seem too unlikely.

However.... I agree the exercise calories coming over from fitbit are too high for me (and probably most people). I think it is because it is the total calories we burn during the fairly active and very active minutes. I believe this number includes calories we would be burning anyway such as our bmr.

So my workaround has been to take an average weekly "calorie burn" from what Spark is pulling from fitbit. Then I loked at the minutes, and estiamtes how much of that is my bmr (I used 60 calories per hour which is a little high for my bmr estimates) then I subtracted that number from the total, I also arbitrarily subtracted a couple hundred more calories so basicall in my case to deduct an even 1000 calories. That seems to help as my spark range and fitbit range are fairly similar now (the fitbit range is only 50 calories and variable by the day so they probably will not exactly match). I just ignore the "you are burning too many calories" message. It wasn't really set up for people like us who are using a fitbit. I hope Spark refines it a little more in time.

All calorie counts and suggestions are ESTIMATES based on a formula for a 'universal body' - or 'average body' - the trouble is that NOBODY HAS A UNIVERSAL OR AVERAGE BODY so look at all of the calorie 'counts' or 'suggestions' as similar to the gas mileage ratings on cars. There are just too many variables for those numbers to actually FIT anybody, whether calories or gas mileage, so it's simply a guideline and YOUR RESULTS MAY VARY.

Since you're losing weight at the moment, I fall back on the adage that if it ain't broke, don't fix it.

It dawned on me the other morning that part of the problem is when fitbit registers fitness calories, the BMR is included in the figure, which must not be the case for spark activities. I wonder, too, if the spark figures are adjusted for your mass, which of course they would be from the fitbit. Too bad I reset my account a while back, so I can't compare a 3 mph walk when I weighed 207 to now that I'm 45 pounds less!

I think the Fitbit overestimates calories burned -- at least that's the case for me; it may be different for others. Having said that, I am just letting it do its thing for now and am not adjusting my SparkPeople estimated calories burned since I think the SP number is closer to reality. I've thought about editing the Fitbit entries in my SP Fitness Tracker to lower the calories burned; but, have not done that as of yet. If I make it too much work for myself, I'm less likely to keep up with it.

Regardless, I have to say I am enjoying my new Fitbit and it is definitely motivating me to walk more stairs especially.

I totally agree with TESSLER65. I've had the One for 5 days, and I have just been logging my food into Spark, ignoring the red WARNING, and moving on. I figured, I've only had it it for 5 days, I have lost some weight already (water weight I'm sure!) and feel great. The FB seems to be happy with the calories...which coincide with Spark (and sometimes if I go over a little, it doesn't seem to mind).

Spark does say that "Little bits of fitness add up" and I guess FB is helping our Fitness Tracker capitalize on it. I figure, until I stop loosing (or gain) I'm not too worried about it. I'm taking the first few weeks to "collect data"...and other than trying to move a little more, I'm not changing anything!

Thanks USMAWife. Good to know I'm not the only one.

Tessler65, as above, it's good to know I'm not the only one. I'm ignoring the admonishments to eat more, adjust my settings, etc. as well. When I was using the BodyBugg I found that I'd have to add a few calories burned to balance out what the BB was reporting vs. how SP was interpreting the activities/numbers I was manually entering.

I suppose in the long run, as long as I'm releasing the pounds, I should shush and keep on keepin' on!

What I did was tweak my FB calorie settings to fall more closely in the range of my SP daily calorie settings. SP gripes continually about me burning too much on my fitness page; SP wants me to eat more. I know, however, that FB is reporting a lot more activity to SP than I would manually record myself, so I'm ignoring the SP "eat more!" warnings on the fitness page. At the end of the day, I find that FB and SP are closely aligned on what I should consume in order to hit my desired caloric deficit for the day.

My ticker reminds me that activity, fitness and good health are a gift I'm giving myself. How generous will I choose to be this month?

the calories between both are off completely and that is one of the things everyone asking for to be the same.



Everybody tells me that they would love to knit, but they don't have time. I look at people's lives and I can see opportunity and time for knitting all over the place. The time spent riding the bus each day? That's a pair of socks over a month. Waiting in line? Mittens. Watching TV? Buckets of wasted time that could be an exquisite lace shawl. ~Stephanie Pearl-McPhee, At Knit's End: Meditations for Women Who Knit Too Much

I ~love~ my Fitbit One. I love that it connects so well with SparkPeople. I question, though, the amount of calories it is saying I burn each day. I believe it's counting the calories accurately, but .. when my weekly calorie burn adds up, it's a tremendous amount. I'm worried if I up my to-burn count in my Fitness tracker, it will bump my to-eat count in my Nutrition tracker.

Right now on my Nutrition page I'm in a comfy calorie range of 1,740 - 2,090 to lose 1 lb a week, and I am losing (although a little more than 1 lb so far) steadily. If I bump up my to-burn count on my Fitness tracker, it jumps my to-eat count to 2,080 - 2,430. That seems ridiculous.

Has anyone had any experience with this? Any thoughts?
Thanks!
