Fitbit not accurately calculating exercise

[Seto123]

Hi everyone

I'm new on this forum but not new to fitbit, I've had mine for almost 2 years.  I have been really disheartened lately as I have noticed my fitbit is calculating too many calories burned for the activities I am doing.  So, bit of background, I decided to get my act together and get in shape in the new year 2018! I've been combining couch to 5k with daily walks.  My walking calories are, I think, too much for my time, height/age/weight etc and I'm feeling quite deflated by it.  I noticed I hadn't been losing weight as I was going off my calories burned for the day, now I feel what is the point of having a fitbit if the estimated calorie burn is way off.  Can anyone advise, thanks in advance.

Personally, all the trackers and cardio machines, and ... well.. anything that does an auto calculation of calories are off. I see a weight loss doctor every month, and she informed me that all the apps, machines, and everything else are all based on assumptions. It will never be an exact *thing* no matter what you use. She advises me to cut the number by 30%-50%. I agree too, and that's what I have been doing.

That being said, I use my FitBit to gauge my effort, and even though (in my opinion) it's not accurate, as least it's consistently inaccurate, but a good overview of what's happening for me.

My Charge2 says my 1.5 hour workouts burn like 1200 calories. I doubt it. I work hard in the gym, but I don't think 1200 is accurate. However, I can safely say that I might be the 500 burn range. Again, nothing is exact, no matter what you use.

I do a 1800-2000 calorie intake daily, and that's below my 2300 BMR number. I was told not to eat below BMR. My TDEE is like 3200. But 1800-2000 works for me, and I do not feel starved at all.

I just try to use some good judgement and go in knowing that I'll never get an exact number on anything.
