How does Samsung Health measure calories?

In this brief guide, we are going to answer the question, “ How does Samsung Health measure calories?”, and provide you with more tips on how to keep a check on your calories.

How does Samsung Health measure calories?

Samsung smartphone comes with a preinstalled app Samsung Health. The app comes with a feature that measures calories burned throughout the day. The app logs daily activities and makes an estimate of the calories burnt with daily step count, exercise activity and sleep time calculation. In this article we will ask more questions regarding how Samsung Health measures calories burnt.

What are calories?

According to an 1863 article in the Journal of Nutrition, titled “History of the Calorie in Nutrition,” a Calorie was defined as “the amount of heat needed to raise the temperature of 1 kilogram of water from 0 to 1 degree Celsius”. In 1925, calories were scientifically defined in terms of joules in which 1 joule is the amount of energy needed to force 1 Newton through 1 metre. 

In terms of calories, one calorie is the equivalent of 4.18 joules. The term Calorie is often used to represent kilocalorie and is shortened to kcal which is widely seen at the back of food products to represent their nutritional values.

How the Samsung health measures calories burned?

When we talk about burning calories, what we are essentially saying that the body burns calories to perform respiration, digestion or temperature regulation etc. The body burns calories while in a completely restful state as well. 

Basal Metabolic Rate (BMR) is the number of calories your body needs to function at rest. The BMR is identified through age, gender, height, weight and daily physical activity. The Samsung Health app calculates the calories burnt during rest, walking and exercise by initially calculating the BMR and using it as a reference.

How accurate are the calorie burnt measurements?

All smart accessories compute calorie burnt by extrapolating information from exercise activity, daily step count, heart rate and general time at rest. None of these methods are very accurate.

It is easily arguable that even if the tracker is inaccurate, it still logs daily progress. The inaccuracy would be by the same number of points, each day. 

Hence, if you sit around most days, the app will clearly show an you burnt more calories on the day you have decided to go for a walk.

Someone willing to log their activity level and maintain a good healthy routine can benefit from this information by knowing where the person spends most of their hours. It would also be useful to someone who is willing to add an exercise regime in their daily routine.
