Sudden decrease in "resting calories?"

Hey guys, recently my GC app has drastically cut what it calculated as my resting calories. I'm 5'11, 167 pounds. It was calculating my resting to be 2040 which is spot on for my TDEE.

Two days ago something changed, and my resting went down to 1720. What gives? I've changed nothing.

Has anyone else seen this?

Did you update your device to a new version of software? At least for the F3 they did this during a beta update and its done the same to my baseline TDEE. Unless they now made this change in the backend.

They're leaving out the sedentary multiplier and just using straight complete rest BMR as the "resting calories now".

Send it a report to support - they really need to change this back as it messes up total TDEE not to mention myfitnesspal adjustments.

Perhaps they need to rename "resting calories" to "baseline" or "sedentary" calories.

Yep, I'm now on the F3HR 3.0 beta firmware. I was thinking that a change in the watch shouldn't matter in GC but I guess I was being a little dense.


I agree, this is not a change for the better. It's telling me that I burned 2200 calories yesterday...that's about 300 too short. Which makes sense, because they cut 300 from my TDEE.



Surprised more people aren't bothered by this.

I know. Its a critical piece to have an accurate TDEE calculated from these devices and their new equation isn't accounting for enough baseline calories. Someone who is completely sedentary at your weight/height would need over 2k a day to maintain. I'm similar weight/height and noticed the drop of a few hundred.

But I'm not sure how many folks understand how the BMR formulas work and the multipliers used to calculate baseline TDEE before any significant steps/exercise.

I really hope they don't try to overcompensate through extra step calories etc because that could mess things up even more.

Here's what happened to mine.

I am just bumping this thread because they do need to be aware of this issue. Their new logic for total calorie calculation has the devices underestimating the calories burned for the day. Here was my example I posted in another thread.

Has anyone else been getting lower calories burned since the update? Yesterday my total was 1951 for the whole day. This seems pretty low to me. My basal metabolic rate has me right at 1600 calories a day and the Fenix has resting calories at 1556 so I am not really concerned about the resting calories. It is the active calories I am wondering about. Yesterday it had me at a total of 395 active calories which seems low. Yesterday I had a total of 13,657 steps which included a 20 minute treadmill run at 6 mph along with 28 floors climbed. I just find it hard that through out the whole day I only burned 350 calories over my bmr calculation. Without any exercise included my total burn should have been around 1867 using this formula 1556*1.2(desk job).

best to also email the ideas team and/or support.

I got this behavior also, it really sucks!
BMR as the TDEE? WTF Garmin?

we want the old TDEE calculation back, or at least a possibility to add own multiplier to the personal settings!

I sent a note to the ideas link. Hopefully they will listen and or respond. Definitely need this changed back or even better an option to configure your own multiplier.

Some common sedentary options
1. Mifflin-St Jeor BMR x 1.2 (typical)
2. Mifflin-St Jeor BMR x 1.25 (what myfitnesspal uses)
3. Custom BMR and multiplier off the Katch-McArdle formula if you know your bf%

YES!!!


I'd absolutely LOVE to be able to set a custom multiplier in GC. That would be awesome. I hope they listen.


It told me that I burned 2100 calories yesterday.....that's it. There's just no way.

Same issue here. Following.

I feel like there's an issue with active calories as well. In the past couple of weeks I've seen workouts that previously burned 600-800 calories burned 400-550 instead.

I really wish Fitbit would make a reliable and durable running watch. I never had these issues with my Charge HR.
