Simply breathing, existing, and essential bodily functions account for the majority of energy expenditure. NETO (non exercise thermogenic output) is another considerably contributing component of energy expenditure. This is physical activity done without significant conscious effort, such as typing, standing and moving during everyday mundane activities, fidgeting, etc. In contrast to exercise, which is activity that is thoroughly planned with conscious acknowledgement of its purpose contributes to the least for most. Exercise really doesn’t burn as much as calories as one would think or desire. Especially since most exercise is done for only so long. Not all day long.
