Fitbit calorie adjustment

I'm just curious as to whether or not people take the fitbit calorie adjustment into account. Sometimes it seems overly high for me. Like for today it's already - 155. Some days I have over 600, 700 calories burned because of the Fitbit.

    I'm not sure how accurate it is. Mine sometimes adds over 1,000 calories if I've been really active. Today I'm on 355 already.

    The size of your fitbit adjustment will depend on the activity level you set in MFP. I'm fairly active, but I set my activity level to sedentary because I like seeing the big adjustments when I'm active. It motivates me.

    I eat most or all of my fitbit adjustment, and it seems pretty accurate for me based on rate of loss over the last few months.

    Yeah I set my level to sedentary as well even though I'm anything but.

    The value that you see on your tracker when you wake up in the morning is your estimated calorie burn for the day so far. You still burn calories even if you are sedentary or sleeping. We estimate your calorie burn based on your age, gender, height, and weight. If your tracker measures heart rate, the calorie burn estimate also takes heart rate into account.

    Your tracker may register movements or restlessness as steps when you're wearing it while you sleep. The number of steps typically measured during these periods is minimal, and should not offset your overall fitness progress. Any steps taken to and from other rooms during the night will also be tracked.

    The size of the adjustment really depends on how accurate you were in selecting your activity level.

    I've been in maintenance for a while now. I have found my Fitbit data to be fairly accurate. As in, if I eat less than my daily burn according to Fitbit, over time, my weight drops.

    The activity record from the device button press is merely to allow viewing those stats for that block of time, you can manually make an activity record too for same purpose. Not logging those calories, merely viewing what Fitbit came up with already.
    If you know you'll manually log a workout to input more accurate calorie burn, the activity record does make it easier to see when the start time was, and figure out duration, and allow seeing the Fitbit stats for that time, rather than buried in the daily stats.

    If you log workout with an existing activity record, it does NOT replace the calorie burn in the record, just the daily stats. If you create activity record manually after logging workout, calorie burn is whatever you entered, though the other stats will be shown for steps & distance.

    So you should expect decent adjustments. An active you burns more calories per day than a sedentary you. :)

    Also, a tip from a Dr was while you are trying to lose weight you do not eat your extra calories burned off. Only stick to you calorie goal for the day. Once you hit the goal weight, then you can eat your extra calories to maintain. :smile:

    It does. I'm in the process is of raising my cals to maintenance and do so with trepidation.

    I do not agree with this. You have to fuel your exercise! I eat back my calories and have lost well over a pound a week for the past 6 months. Doctors often have no clue about nutrition.

    I've been tracking for about 4 months both in MFP and spreadsheet and found my weight loss is tracking almost exactly what it should figuring in my MFP deficit + all Fitbit calories burned. So fairly accurate for me as well.

    Great info and experience in this thread. Thanks! I am set at sedentary on MFP so I often get adjustments upwards of 700-800 calories from my Fitbit. Glad to hear people trust their Fitbit and that it has proven accurate. I'm still in the testing phase with mine.

    Do you all eat all of your fitbit adjustment calories, or just some of them? I always eat a few hundred back but am wary about eating the whack in case it's overestimating.

    In my opinion, you should ALWAYS set your activity level on MFP to sedentary if you are using a device that syncs up and adds your exercise. The FitBit will include any movement (walking to the fridge, walking to the bathroom, walking around the building, etc.) as exercise. If you set your level to lightly active or active or anything else, you are double-dipping on those "normal" activity calories.

    Also, make sure allow negative adjustments is checked in your settings. This way, it will remove calories on days you may not be as active.

    Finally, as far as eating your exercise calories back... you should. That is what MFP is all about. However, since no device is 100% accurate at determining exactly how many calories you burn, you may have to adjust. Since this is a lifestyle change and not a quick fix, I would eat all of your exercise calories back to start and check your weight weekly. If - after a few weeks - you are gaining weight or maintaining weight, then adjust accordingly. But not eating your exercise calories back (at least some of them) is not the correct way to do it. If you eat only 1,200 calories in a day but you exercise really hard and burn 900 calories, you are netting only 300 calories which is NOT safe.

    The bolded part is not accurate. If you set your activity level to something other than sedentary, you're not "double-dipping," you'll just get a lower fitbit adjustment (or a negative adjustment). It really depends on your preference.

    I set MFP for sedentary and took the FB calorie adjustments and found that even at "maintenance" I was still losing about a pound a month.

    My bad, good to know. Who knew technology was so technologically advanced.

    Yeah eat them all

    But remember fitbit extrapolates to end of the day based on what you've done...so if it's 10am and you've just done a 5 mile run it will assume that level of activity will continue till midnight ...and each time you synch it will readjust

    Over time it learns your activity rates and the differences are smaller...but at the start you could end the day with 100 cals spare and synch the next morning and realise that you actually overate by 150 the previous day

    So always synch as late as possible and leave a bit spare for readjustments next day

    That depends on what method you are using. Unlike other methods, MFP does not factor intentional exercise into your calorie allotment. Yesterday I walked/hiked for 65 minutes, practiced yoga for 75 minutes, and went to the gym and lifted weights. I absolutely need to eat extra to fuel that.
