How Does Fitbit Calculate Calories Burned

It also calculates your distance traveled, counts the floors climbed, etc;

Let’s take a view on how the Fitbit Calculate the calories burned:

So before getting into the article lets clear about-

What is BMR: It is Basal Metabolic Rate. The rate at which you burn calories at rest to maintain vital body functions that include your breathing, blood circulation, and heartbeat and your activity data to estimate your calories burned.

Note: If your device tracks your heart rate, the heart-rate data is also included, especially to estimate calories burned during workout/exercise. The number you see on your Fitbit device is your total calories burned for the day.

Key Note: Your body burns calories even if you’re asleep or at static position i.e. enjoying a movie by leaning in a sofa at your home and you see calories burned on your device when you wake up and will notice this number increase throughout the day.

Like Fitbit and Withings, it uses age, gender, height, and weight. Like of (BMI) body mass index, which is best at estimating body composition among large populations, but aren’t need on-point when it comes to every single person.

How does your Fitbit Device detect your Heart Rate

  • When your heart starts beating, your capillaries expand and contract based on blood your volume changes.
  • To determine your heart rate, the optical heart-rate sensor in your Fitbit device flashes its green LEDs light many times/sec.

Working:

  • It uses light-sensitive photodiodes to detect these volume changes in the capillaries above your wrist and then your device calculates how many times your heart beats per minute. The optical heart-rate sensor detects a range of 30-220 bpm.
  • The optical heart-rate sensor also uses infrared light to determine when the device is on your wrist to improve the accuracy of your heart-rate data.
