Tdee when sitting all day

Hey!
Calculated my bmr to be 1678 and tdee 2013
using the sedentary activity level. Now the thing is, i dont go outside at all, my only movement is walking around my house.
So how can i burn over 300 calories more than my bmr by doing nothing?

    BMR is with you doing nothing. It uses energy to move your body thru your day. Granted, if you're very inactive it would not hurt to throw in some extra movement. Walk or jog in place occasionally, for example.

    BMR = laying in bed all day doing literally nothing (most people describe it as what you would burn in a coma)

    TDEE = any extra activity plus your BMR. I know you put sedentary, but they account for the fact that you are most likely not in a coma. So you do burn some extra calories even if you just brush your teeth, lift your hand to your mouth multiple times a day just eating and drinking, sitting up right at all and engaging those muscles to do so, walking to the bathroom, and walking to the couch. And that's just an example of the most sedentary person I can think of.

    So even, sedentary, your TDEE should be a little higher than your BMR.

    eating, digestion, talking, sitting, fidgeting, thinking, etc.

    Your TDEE will be higher than your BMR but how much higher depends on your activity. I used to be VERY seditary. I work 10 hour days at a desk. When I first got my fit bit, I was barely taking 2000 steps a day. At that rate, my estimated TDEE was about 100 calories too high.

    It's all an estimate anyways. The best thing to do is try it for a few weeks and see how you sit. If you've lost weight, you are in a good zone, if you haven't lost or you've gained, you need to reevaluate. You can also look into getting an activity tracker (like the fit bit) to give you a better esimation.

    Your BMR is basically what you would burn in a coma. Are you more active than being in a coma? Do you put clothes on, chew your food, walk to the bathroom? Yes? Then there you go.

    If you want to test it, eat at your TDEE for a couple of weeks, see if any changes happen. If you are really that sedentary, you will gain a little bit of weight (like, less than a pound but still) and then know that your personal TDEE is lower than that.

    While I love my Fitbit, a simple $5-15 pedometer can do the same thing for less $. Wear it for a week, noting your daily step count. Then use that information to challenge yourself to do 500/day more, or 2500/day more or whatever seems a reasonable goal for you...

    This is referred to as NEAT - non-exercise activity thermogenesis.

    Don't forget to add TEF too (thermic effect of feeding) - the calories used digesting food.


    TDEE = BMR + NEAT + TEF + exercise

    Even without exercise the body can easily burn those extra 300 cals per day.

    hmmm.... I've never heard of TEF (I guess I assumed it was part of BMR or something).

    Learn something new every day.

    Still the point still stands that even sedentary people aren't completely motionless.

    You use 10% of your energy eating and digesting your food. Well, That's what the huge scooby formula told me when I calculated mine. There is so much misinformation on the net, so don't hold me to that.
