How Accurate Is the Fitbit Calorie Burn Counter?
Fitbit devices are incredible pieces of technology that can track your every move and give you detailed information about your fitness and activity levels. But is all of that detailed information accurate or just for show?
While there are countless data metrics to look at, we’ll look at Fitbit’s calorie counter in this article. How reliable and accurate is Fitbit’s calorie burn counter?
How Do Fitbit Devices Calculate Calorie Burn?
Fitbit’s fitness features can be utilizedbeyond just counting steps, and one of the most useful features is the calorie burn counter. But how does Fitbit calculate the number of calories you’ve burned?
Fitbit uses your heart rate as a key part of its calculation. It also takes into account your height, weight, age, and gender to give you a better estimate of how many calories you’re burning throughout the day.
Here are the two most important factors that determine total calories burned on your Fitbit device:
Fitbit’s calorie burning accuracy has come a long way since its early days. And while there’s always room for improvement, Fitbit devices are still some of the most accurate fitness trackers on the market.
The short answer is that Fitbit’s calorie burn counter is generally accurate. However, there are a few factors that can affect its accuracy.
According to a 2019BBC article, one study found that the Fitbit Charge 2 was underestimating the calories burned by participants during running by 4 percent and overestimating calories burned while walking by more than 50 percent. The study also found that the calorie burn estimates were more accurate in higher-priced trackers.
What Factors Can Affect the Accuracy of Fitbit’s Calorie Burn Counter?
There are a few factors that can affect the Fitbit’s calorie counter accuracy, including:
Fitbit Calories Burned Accuracy by Model
Every Fitbit model is slightly different, so the accuracy of the calorie burn counter will vary by model. Newer and more expensive Fitbit models tend to be more accurate than older, more affordable models.
For example, the Fitbit Charge 4 has been found to be one of the most accurate fitness trackers on the market. A study conducted byWareablefound that the Charge 4 was highly accurate when it came to tracking heart rate and steps. The upgraded model—the Fitbit Charge 5—is even more accurate than the Charge 4.
The Fitbit Inspire 2, on the other hand, has a less accurate calorie burn counter. That said, based on the accuracy of other Fitbit models, it’s safe to say that the Inspire 2 is likely accurate within a few percentage points.
However, as an entry-level model without a built-in GPS, the Inspire 2 may not ever be as accurate as the more expensive models like the Charge or Sense. With theFitbit Inspire 3’s big improvements, it may be worth splurging on this newer model rather than the Inspire 2.
Making the most out of your fitness trackeris all about understanding its limitations. No fitness tracker is perfect, and they all have their own strengths and weaknesses. If you want to knowwhich Fitbit model is best for you, we’ve got you covered.
How to Improve the Accuracy of the Fitbit Calorie Burn Counter
There are a few things you could do to improve the Fitbit calorie accuracy.
What if My Fitbit Says I’m Burning More Calories Than I Actually Am?
If your Fitbit says you’re burning more calories than you actually are, don’t worry. Remember that the calorie burn estimate is just that—an estimate. It’s not going to be 100 percent accurate.
Your Fitbit tracker may be overestimating your calorie burn if you’re very active. Because the tracker uses your heart rate to estimate calorie burn, it may not be able to estimate caloric burn as accurately for people whose heart rates are frequently high. At the same time, Fitbit sensors may not measure as accurately for people who are more sedentary or obese, according to research inBiomedical Optics Express.
If you notice some big discrepancies between your Fitbit calorie burn estimate and the calories you actually burn based on other forms of measurement, you can try factory resetting your Fitbit. If yourFitbit won’t sync properly, it may not be able to track your activity level and calorie burns accurately.
Does Fitbit Provide an Accurate Calorie Burn Estimate?
The question sounds simple—how accurate is Fitbit’s calorie burn estimate? But the accuracy of the Fitbit calorie burn counter will vary depending on the model you have and how you use it. That said, Fitbit trackers are generally accurate to within a few percentage points.
So, if your goal is to get an idea of how many calories you’re burning, a Fitbit tracker is a good option and relatively accurate. Just remember that fitness trackers are great motivational tools to track and inspire your progress, but they’re not meant to provide 100 percent accuracy on any statistic, including estimated calories burned.
Both wearables can help you achieve your fitness goals. But which one deserves your hard-earned money?
My iPhone does it all, but I still need my dumb phone.
OneDrive is one of the best, but it has a catch.
Goodbye sending links via other apps.
