Calorie Inactivity Between 1 MET and 1.5 METs
1 Metabolic Equivalent (MET) corresponds with Resting Metabolic Rate (RMR). RMR is the total number of calories burned when your body is completely at rest. So why does Oura use 1.5 METs as the lowest threshold for activities which contribute to your daily active calorie burn?
During sedentary activities, METs range from 1 to 1.5. Sedentary activities include dining, or lounging while watching television. In contrast, active calories relate to inherently active tasks or activities (e.g., household chores). Physical activities typically result in a calorie burn greater than 1.5 METs.
Active calories above 1.5 METs are typically associated with active energy burn. Using 1.5 METs as the threshold for active calories prevents accumulating large amounts of active calories from low-intensity activities. This increases the accuracy on your Activity tab and doesn't exaggerate calories burned while you're seated or at rest.
