For example, if the individual does not accurately enter their weight, height, or body composition into the device, the calorie burn estimates will be less accurate.
D. Your Body’s Basal Metabolic Rate
Your basal metabolic rate (BMR) is the amount of energy that your body needs to perform basic functions such as breathing, circulation, and cell production while at rest. This is often referred to as your “metabolic rate” and it is an estimate of the number of calories that your body burns in a day to sustain basic functions.
BMR is influenced by several factors, including your age, sex, weight, height, and muscle mass. In general, men have a higher BMR than women, and people with a higher muscle mass have a higher BMR than those with a lower muscle mass.
It’s important to note that BMR is different from total daily energy expenditure (TDEE), which takes into account all the calories you burn throughout the day, including those burned during physical activity and digestion.
Knowing your BMR can be helpful in determining an appropriate calorie intake for weight management. However, it’s important to remember that BMR is just an estimate and individual needs may vary. A professional nutritionist or dietitian can help you determine your specific calorie needs based on your personal circumstances.
Limitations of Fitbit Devices for Tracking Calorie Burn
Fitbit devices are a useful tool for tracking physical activity and monitoring health and wellness, but they have several limitations that can impact the accuracy of calorie burn estimates. These limitations include:
