Calorie burning?

[The Raging Bull]

How many calories does the body naturally burn per day? And what helps it naturally burn more etc.? (Obviously not including exercise). I have been wondering about this for a while.

Help please

It all depends on your weight, height, and sex. Average person I think it's 1,400 calories?

The U.S. RDA of nutrients is based upon diets of 2,000 and 2,500 calories per day. These are considered the average calorie expenditures of the average woman and man in the United States.

Was he asking how much we burn just breathing or how much the average person burns waking up and doing normal tasks other than any exercise?

The more muscle you have, the more calories your body burns at rest.

when i eat at night and run in the morning and weigh myself i lose like 3 pounds like magic but i gain it back by eating

It depends on way to much for a simple answer man.
Lean muscle burns up more,
****y foods (most) (uhh and REAL ****e) have chemicals that make respiration (cellular respiration) go faster
Sleep- When you're fatigued you actually metabolize slower
How much you think-
I'm serious. Your Brain uses up glucose petty fast, it also doesn't really make use of sugar polymers, so don't be so shy about a few simple sugars, without em' ur not thinkin as well as you could, and are increasing risk to injury
Size, build, sex, genetics...
I could go on man, but I figured the first few were ones some may not know.

Yeh, I was asking how much the body burns without exercise. So when we're doing light tasks etc.

Thanks for the answers guys. I realised how vague my question was when I posted it, but thanks for the help.

A rough estimate of BMR is as follows:
Men's BMR in calories = 1 X Body weight in kilograms X 24 hours
Women's BMR in calories = 0.9 X Body weight in kilograms X 24

(to calculate your body fat in kilograms, divide your weight in pounds by 2.2)

Now, once you have this number, decide which body fat range you're in, and multiply it by the Lean Factor multiplier in parenthesis.

Lean Factor Chart
-Men Under 10%, Women under 14% 105% Multiplier - (1.05)
-Men 10% to <14% – Women 14% to <18% 100% Multiplier - (1.0)
-Men 14% to <20% – Women 18% to <28% 95% Multiplier - (.95)
-Men 20% to 28% – Women 28% to 38% 90% Multiplier - (.90)
-Men over 28% – Women over 38% 85%(0.85) 85% Multiplier - (.85)

This is your adjusted BMR. This is what a person at a specific body fat level burns while at rest (not asleep, but not doing anything but sitting down). There are other calculations you can do to estimate your daily caloric expenditure, but this gives you a rough idea of the amount of calories you a basal rate.
