 SLYSAM SparkPoints: (43,184) Fitness Minutes: (110,991) Posts: 1,474 11/10/12 2:24 P Just to add, the base of it is what Courtney describes for time that has passed if you have calorie estimation turned "on" and are not wearing the fitbit or not moving. If you are wearing it and move around enough, it is more like an estimate of your bmr (the calories you bur at rest so less than your sedentary burn) + how fitbit estimates your activity calories. How fitbit estimates your activity calories has a lot to do with how much you move (steps) and how fast they are in any given minute. Notice on the fitbit dashboard there is a graph of calories burned per five minutes, the graph has colored spikes. The colored spikes represent the activity level that five minutes is classes as... gray = sedentary, teal=lightly active, yellow=fairly active and red= very active. Fitbit actually does this per minute as the pie chart for "time active" breaks this down per minute of the day. So it is tracking how much you move (to the extent it can) even if it isn't intentional exercise and more movement would result in adding more activity calories on top of your base bmr calorie burn. Just one side comment, I can't really comment whether 2000 calories is high for a sedentary burn. I think it might be quite typical for some people considering that a lot of people eat more than 2000 calories a day (some restaurant meals can run that in one meal). It can be pretty hard to compare calorie burn estimates among people of different heights, weights, ages, and genders. Some people might have a 2000 calorie burn just from sedentary activity while others have to work very hard to reach 2000 calories (or may not be able to). It really varies by the height, weight, age and gender and how they balance out. Similar to the common discussion on "how many calories did you burn today?" in this board. Some people routinely post a thousand or more exercise calories, yet I would have to workout for three hours or more to get my heart rate monitor to credit me with that many calories burned. It is kind of meaningless to compare unless maybe you are comparing with people very similar to yourself. It might make more sense for you to run your stats through a couple of the popular bmr/rmr calculators to see what kind of numbers they give you. They are just estimates, but each method gives me a slightly different number. Keep in mind the number these give you should be slightly lower than your "sedentary" calorie burn for the day (as even sedentary assumes some activity while bmr/rmr is meant to be what you burn resting all day).
