These devices typically track motion and heart rate. Wearable devices, such as fitness trackers and smartwatches utilize a combination of sensor data and algorithms to estimate energy expenditure. TDEE is then calculated from REE by adding the two additional energy expenses, thermic effect of food and physical activity. By analyzing the ratio of oxygen used to carbon dioxide produced, scientists can estimate the number of calories a person burns at rest. The body uses oxygen to metabolize nutrients and create energy, while the carbon dioxide produced is a byproduct of this process. During an indirect calorimetry test, a person’s oxygen consumption and carbon dioxide production are measured. The most accurate laboratory test to measure REE is indirect calorimetry.
