Forerunner 965 doesn't track NEAT or calories burned accurately

I have seen a similar thing, however, you need to take into account that of the 1291  calories you would have some of those at rest anyway.  That may account for 150 or so calories you have to earn back.  Where did you get the 14k steps for the run from, is that a guess or is it shown somewhere?

Although it’s not perfect I find garmin  to be closer to reality than any other brand. I have been maintaining my weight eating around 3000 to 3200 calories a day. My average calorie burn in garmin is around 3100.  So, at least for me it seems fairly accurate.   

I think it can look demotivating, but Fitbit, apple etc, grossly over estimate it, at least for me.  

Finally, calorie burn will always be tricky to estimate from a watch so I would use it as a guide and not a rule.  If weight is a concern then tracking weight and altering your diet is far better than believing your watch.  

14,000 steps came from the Fitbit. Since the overall step counts for the day were pretty close, I think it's a good guess.

1291 seems to be on target with what nearly 2 hours of running would burn so it shouldn't be included in the RMR.

Also, the Garmin seems to think I have the RMR of a sedentary person, but I average 25k to 30k steps a day, and work out 7 days a week including running, heavy weight lifting (squats, deadlifts, bench).

Is there some setting I am missing?

If I log walking as an activity, it says I burn a lot more than if I don't log it as an activity. 

Ok, steps aside.  

If you look in the activity you will see that calories show active and resting. My run yesterday, 7.2 miles, 1 hour. Active calories 784, resting 87, total 871.  I guessed at 150 for your run but you can see it. in other words, had I not gone on a run I would have burned 87  calories   

Your calories on garmin don’t include any exercise, they are based on rmr with a small amount of calories added on for daily life. For reference mine is 2033 a day which is based on age, weight, height and gender.   Overall my burn for yesterday was 3121 and includes another 2 mile walk.

You are not missing a setting as far as I know.  As long as your age, weight, height and gender are correct you are good to go. May also be wise to check your max hr is correct as well.   

You are correct that you do burn more when you log as an activity. I believe this is due to the heart rate monitor takes your pulse more often.  One of the reasons that I have a walk activity with no gps for when I go for a walk at lunch. This is and issue that’s well documented in this forum.  However, for pottering steps, this is fine, it’s only if you go for a brisk walk that it becomes an issue. Remember that walking at normal pace doesn’t burn that many calories.   

Thanks for the information!

There's at least 500 calories between my Whoop and Forerunner 965. My third day with Forerunner and now I am totally confused about both. Today I set my max heart rate to 164 on Whoop, before it was 170, same as Forerunner (164), I'll monitor the differences for another couple of days. Although all devices' calorie counts are all estimates there shouldn't be that much of a difference. I am using Carb Manager for a calorie deficit to control my diabetes if I enter too many calories then think that I am in a deficit whereas I am not this will ruin my health. However the reason why you buy a tracker (650 USD) is the opposite: to be healthier. 

Watches (of any brand) are not accurate for calorie burn.  It’s very hard to get accurate figures. You should only really track calories and use the scales to check your weight for a medical condition.  

I know that. But somehow we need to have an idea for calories in-out. Why else would people buy trackers? 

It does give you and idea.  However, they shouldn’t be relied on. 

I guess your issue here is that you have 2 differing values.  I’m guessing that you want the garmin to match the woop one.  That isn’t going to happen.

I would say that Garmin is the more accurate.  Apple over estimate calorie burn.  Not sure about woop.  Does that show 500 more calories than Garmin. If so I would ignore it.  

I disagree.

Garmin is only more accurate for people who are sedentary and do 1 workout a day.

But if you are active throughout the day, then the Garmin will underestimate calories burned by > 50% depending on how active you are.

*based on my two weeks of owning a Garmin Forerunner 965 but 6 months of counting every calorie and knowing how much my TDEE compares to the numbers shown on my FitBit Charge 5.

My main problem is: I am a diabetic, following keto, using Carb Manager. It's very good that Forerunner 965 talks to CM, automatically entering my burnt calories other than resting. However my settings are such that CM deducts these calories from my macros i.e. carbs, protein, fat. Then I have more space to eat based on this. But if there's an over estimate of calories burned that means everything I am doing is in vain.
