FitBit Calorie Adjustment is super confusing.

Hey, I used to have a FitBit in 2014, and wore it for around 8 months. If I ran approx 5 miles, and the treadmill showed that I had burnt roughly "600" calories, then my MFP calorie adjustment when it synced with my FitBit was also around "600" calories.
I recently got a new FitBit Flex, and was so excited to not manually have to log my runs anymore. I already have a deficit worked into MFP, and my daily goal is 1375cal. My MFP account, and my FitBit account are connected, and my calorie goal also shows up on my FitBit account.
Here's where it gets tricky.
Yesterday I had eaten around 1200 calories before suppertime. I run before I eat dinner. I ran 5 miles, and burnt 600 calories. FitBit had showed that over the course of the day, I burnt 2200 calories in TOTAL. However, my MFP calorie adjustment was ONLY 298 additional calories, bringing me up to 1,673 calories I could eat yesterday before, according to MFP, I was "over."
FitBit never used to do this to me. I have checked, and re-checked settings and I'm not sure what to do. I'm already going crazy and it's only been one day. I have read forum after forum and I'm at my wits end. Someone please help!!

What is your activity level set to? My first guess is that you didn't move "enough" the rest of the day (that is, as much as your activity level projected) so that your exercise didn't give you 600 calories more -- it only brought you closer to even. This is why I have my activity level set to sedentary -- to minimize things like this.0
-
Okay, so based on your FitBit your TDEE yesterday was 2200 calories. Your adjusted calorie goal was 1673 calories. That results in a daily calorie deficit of 527 calories or just about a pound per week weight loss.
Do you have MFP set for a 1lb/week rate of weight loss?0 -
I already have a deficit set in MFP that is just above my BMR (afterall 1375cals/day is basically nothing, as I'm 5'8" and 164lbs) Lol. I feel like FitBit is doubling up on the deficit maybe? I already have my activity level set to sedentary, and my "goal" is to lose 1lb/week.
All I know is, that eating less than 1600cals/day, while also running 5 miles a day is not healthy nor sustainable and I miss the way FitBit used to account for that. I can't figure out why it's not adjusting properly.0 -
Since your goal is to lose 1lb/week (500 calorie deficit per day), your FitBit worked exactly like it was supposed to. You were probably less active than "sedentary" during the day, which resulted in a low TDEE.I already have a deficit set in MFP that is just above my BMR (afterall 1375cals/day is basically nothing, as I'm 5'8" and 164lbs) Lol.

How many calories did you burn the rest of your day (not counting the run)? I can run, burn a ton of calories, and still have a low burn day overall if I'm not moving very much (um, not that I'd ever do that!)0 -
Is your height and stride set in FitBit? The website shows me a chart of how many calories and steps it's giving me per every 15 minutes. During your run, how many calories was it charting per 15 minutes?0
-
If my caloric goal in MFP already includes a 500cal/day deficit, (as I said, 1375c/day is justtttt above my Basal Metabolic Rate) how do I fix this? I think I'm basically double dipping now in terms of deficits.

My TOTAL tdee was 2200, my run accounts for roughly 600 of that, meaning that I burnt an additional 1600cals throughout the day.0 -

You're not doubling your deficit. FitBit said your TDEE was 2200 calories, a 500(ish) cal deficit was subtracted, and your goal was adjusted to 1673 calories.If my caloric goal in MFP already includes a 500cal/day deficit, (as I said, 1375c/day is justtttt above my Basal Metabolic Rate) how do I fix this?

If my goal on MFP includes a deficit already, then before I ever had the FitBit, when I would run, and enter my workouts into MFP, it added all those calories to "what I had left" to "eat" for the day.. Now, I'm "getting" about 1/3 of them, and I don't know what to do. Something's not right.0
-
in the last few months the way MFP tracked the fitbit adjustment changed. They take into account current burn and expected burn. The outcome was that calorie adjustments went down A LOT. I think they did this because before the calorie adjustment given by fitbit was too high.0
-
Before, MFP assumed that you were burning enough calories throughout the day to be considered "sedentary." Now you know that you're not.If my goal on MFP includes a deficit already, then before I ever had the FitBit, when I would run, and enter my workouts into MFP, it added all those calories to "what I had left" to "eat" for the day..

Yesterday you only burned 1600 calories without your run. Without your FitBit, you were assuming you burned 1870 calories per day with no exercise.
ETA: Also, do you have negative adjustments enabled? This will help show you how your actual TDEE is comparing with your MFP calculated TDEE throughout the day.0 -
Something has definitely changed. My caloric intake setting on MFP already has a large deficit calculated into it, therefore ALL exercise calories should be able to be eaten back. I have used this method before and lost 20+lbs, no problem. I thought having a FitBit again would simplify things, and instead it leaves me feeling mentally defeated and hungry

I've used Fitbit + MFP since 2013, and it's never worked like that. Your Fitbit burn is TDEE, and adjustments are the difference between your Fitbit burn and your MFP activity level (sedentary, lightly active, etc.).
Connect your accounts at http://www.myfitnesspal.com/fitbit
Set your goal to .5 lb. for every 25 lbs. you're overweight: http://www.myfitnesspal.com/account/change_goals_guided
Enable negative calorie adjustments: http://www.myfitnesspal.com/account/diary_settings
Ignore your Fitbit calorie goal and follow MFP's, eating back your adjustments. No need to log any step-based activity—your Fitbit is tracking it for you. Log non-step exercise (like swimming or biking) either in Fitbit or in MFP—never both. Exercise logged in MFP overwrites your Fitbit burn during that time.

Thanks for your help everyone. I still haven't figured any of this out. And I'm still hungry. And I still run 5+ miles a day. And my BMR is still 1575/day. And FitBit still recommends that after running 5+ miles, I only eat 1600cals/day.. Neat.0
-
Adjustment your deficit then. I used to have my loss set at 2 lbs a week and it was restricting my calories waaaaay too much. I have it now for .5 and I can eat enough where I am not starving all the time.0
-
Change your weight loss to .5lb/week instead of 1lb/week. You'll have an extra 250 calories to eat per day.Thanks for your help everyone. I still haven't figured any of this out.

Fitbit prorates your calories by time of day—and goes below 1,200. As I said above, ignore it and follow your MFP calorie goal.
If (and only if) you enable negative calorie adjustments, you'll be eating TDEE minus deficit.0 -
I have mine manually set at 1375. I have a BMR of 1575, which means if I laid in bed all day and did NOTHING, I would burn 1575cals.
I NEVER use MFP's recommendation for 1.5lb/week or 2lb/week because I feel that 1200cal/day isn't healthy for ANYONE.0 -
Fitbit and MFP don't care what you manually set it too. it has its own set of algorithms. Why don't you just set it for 1 or .5 lbs loss and follow what MFP says. Works pretty well for me.0

So here's what your FitBit said:
-You burned 1575 calories doing nothing.
-You burned *something* doing your run (we're not sure exactly, but your FitBit webpage would have a chart showing its calculation)
-You burned *something else* doing dishes and getting dressed and walking to your car
Your FitBit says that those things added up to 2200 for the day. Is it possible you don't burn 600 calories running? We have similar stats and I probably would only burn about 400 ADDITIONAL calories (over and above my BMR for that period) running 5 miles.0 -

No, I definitely burn that much. The treadmills says it (I enter height/weight) and matches up within 10-15cals of what MFP says too (when I used to manually enter my workouts) ..you're probably not running as fast as me.

I would trust my FitBit burn over what the treadmill says, personally. MFP is notorious for overestimating burn. Also, the more efficient/better you are at running -- ironically -- the fewer calories you burn (for the same distance) due to momentum and muscle adaptation and your heart simply getting better at delivering oxygen.0 -

Oh I'm aware that as you adjust, you have to increase the challenge. I'm training for a half marathon, so I'm constantly increasing speed, distance and sometimes I throw in a bit of an incline. I run 5 miles now, at a speed of 6.5mph. I also do HIIT sprints 5-6 times per run, at a speed of 9mph. A month ago, I could barely run 3 miles. So I am getting better, running faster, and running longer, to achieve the "burn" I desire. Does that make sense?0 -
Your fitbit is new. Did you have a complete 24 hour day?0

Sure, but does it make sense that I suspect each of your runs is not exactly 600 calories? No matter what the treadmill says?0 -
The fitbit "exercise" adjustment is NOT an exercise adjustment; it is a TDEE adjustment.
Set yourself up as @editorgrrl suggests, using 1lb loss (500Cal deficit) for MFP, with negative adjustments enabled and eat as per MFP's suggestions as long as your Fitbit and Mfp are synchronizing properly.
Since you want to set yourself to eat 200 Cal less than MFP suggests, and assuming you're up and about till midnight, eat to 200 Cal less than MFP suggests including eating back your complete exercise adjustment.
IF you are not setup as sedentary in MFP and if you do go to bed before midnight leave an extra 100 to 200 Cal buffer space to compensate for your reduced late evening activity level... this compensation should be minimal if you're setup at the sedentary level in MFP.
Read @heybales 's FAQ in the Fitbit group as to WHY you should be choosing all these settings.
For running and walking activities the Fitbit TDEE calculations are pretty darn accurate unless there is a settings or hardware issue.0
