So I've been calculating my RMR to get a sense of the calories that I need per day to just maintain current weight. I use the calories per hour website for this.
After you enter your information, they give you an "activity adjustment" since RMR is literally just the calories burned during a day of complete rest.
For example, someone with an office job and sedentary should adjust it by 1.2, etc., someone that exercises 3 days a week and is moderately active would adjust by 1.55.
Here is my silly question. Does the adjustment factor assume in a typical day this is the exercise you would get (so that if on *a specific day* you did nothing, you need to use a lower calorie count).
Or, alternatively, does it assume that someone who is generally active throughout the week has more muscle mass and even if *on that day* you didn't exercise, your metabolism is still burning calories at this rate.
To be conservative, I always use the "sedentary" calorie adjustment even if I typically do exercise quite a bit throughout the week (mostly walking).
How do you interpret the adjustment factor? Hopefully my question makes sense.
