*trigger warning: I will be discussing calories and calorie needs here. If that’s triggering for you, skip this post! If you’re not familiar, indirect calorimetry is a tool used to assess energy expenditure and fuel utilization in the body by measuring oxygen consumption and carbon dioxide production. Basically, you breath into a tube for about 20 minutes, and a machine does a bunch of high level calculations to determine your resting energy expenditure (REE), and therefore the minimum number of calories you’d need to consume in a day at rest to meet your body’s needs. The information I received also included the minimum number of calories I needed for general every day activity (like walking to the grocery store).
