Energy Expenditure

What is energy expenditure?

Energy expenditure, also known as calorie burn, is an estimation of the amount of energy a person uses when carrying out various activities by measuring their heart function.

Why is understanding energy expenditure useful?

Effective monitoring of an individual’s energy expenditure and caloric needs can help control and manage health and wellness.

Obesity is often linked to health complications such as type 2 diabetes, coronary heart disease, stroke and certain types of cancer as well as generally reducing the quality of life.

“63% of UK adults are overweight or obese. This equates to an estimated 35 million overweight or obese UK adults.”

Therefore, being able to control obesity could be lifesaving.

The most reliable way of combating obesity and maintaining a healthy lifestyle is through understanding your energy expenditure and balancing it against your food.

Monitoring energy expenditure using ECG

ECG biometrics could prove to be an integral part of understanding energy expenditure, with more personalised, detailed, and accurate health data insights.

Using an ECG signal coupled with metadata, we can determine an accurate measurement of the caloric needs per individual.

The HeartKey® Energy Expenditure algorithm takes in a user’s physiological parameters and calculates the calories burned over a period of time.

Validation

HeartKey® Energy Expenditure algorithm performance validation is available under NDA.
