how many calories do you burn in one day just from daily functions?!

i a 25 year old woman , 5'4, decent shape, 120 lbs
The results of your calculations are: BMR 1,381 RMR 1,297
For an explanation of BMR and RMR and important notes on the accuracy of these calculations, please see our FAQ entitled, What do BMR and RMR stand for? While BMR is much more widely used than RMR, our FAQ explains why RMR is likely to be more appropriate for your needs.
As BMR and RMR only represent resting energy expenditure or calories burned during a day of rest, an adjustment must be made to reflect activity level. This can be done by multiplying your BMR and RMR by an activity factor:
Factor Category BMR RMR
1.2 Bed Rest 1,657 1,556
1.3 Sedentary 1,795 1,686
1.4 Active 1,933 1,816
1.5 Very Active 2,072 1,946

What is daily function? Nomally a person is 2000 to 3000 calories

you burn 1800 calories.

it all depends on your height and weight. there is an equation to determine your daily caloric expenditure. but if you are over the age of 14 and in normal shape, you burn approximatley 2100 per day, more if you are more active.

It all depends on what your normal "daily functions" are..the rule of thumb is that you burn 2000 calories a day just doing what you do..but some people do more than others..if you spend your day sitting at a desk and don't do nuch of anything when you leave work then that could be less.

The nutritional formula to answer this question is called the Harris-Benedict formula and it will provide you the minimum amount of calories you burn just to survive everyday.
For a woman this formula is:
B.E.E. = 655.1 + (9.563 x kg) + (1.850 x cm) - (4.676 x age)
From there you multiply the BEE by an activity factor of 1.2-1.3 because you are walking around and not laying in bed all day. After putting in your info you will burn about 1700 Calories per day from just walking around during a normal day.

Well I have asked my self the same question. I have search the web and come up with a equations to help out, Well just a basic count of the calories you need in a day. So if you take your weight multiply by about 14 (for woman) 16 (for men), will give you your calorie count for the day. This count should keep you at the weight you are right now.

So your 120 X 14 = 1680
