Fitbit HR accuracy?

dblanke01

Anybody have any guesses as to the calorie count of the Fitbit HR? I’m 37F, 135, moderately active (walk 7000-10,000 steps everyday plus either weight lifting or HIIT 5 days/wk). My Fitbit is calculating between 1800-2000 calories.

What's happening with your weight given how much you are tracking as having eaten? That will be the way to determine how closely your fitbit is getting your daily calorie burn.

My guess is that it's probably mostly accurate for your interval work and step work and less (to not very) accurate with the weight training. If your weight training is done in a circuit training format it might be more accurate than if you are doing sets with 2 to 5 minute rests between.

Sounds about right to me, and I agree with Maxxit: track your food as accurately as you can while using your FitBit numbers. They are spot on for most people, but not for everyone. It's your experiment to run.

Hr monitors particularly fitbit and Garmin are the most accurate you can get. The technology is not there to be 100%. They are accurate enough to trust the numbers, the only time I would question them is when you get loads of steps on a long car trip or on a ride on lawn mower. I'm waiting for the technology to know the calories we put in without us having to record it manually.

They don't measure calories, they estimate. It's a statistical estimate, somewhat personalized, but founded on algorithms that rely on large-scale research studies. They'll be quite close for most people, further off (high or low) for a few, and significantly off for a very, very few. That's pretty much the nature of statistical estimates.

Follow it for 6 weeks or so, compare results to expectations, then you'll know. Over time, if it's not strictly accurate, it'll be likely to be off by a similar magnitude (percentage), then you can adjust intake accordingly, and rely on the adjusted figures.
