do you burn calories while sleeping or setting?

Question

Answer 1

Yes but they don't count.
Stop trying to talk yourself out of getting some exercise.

Answer 2

Sure do,but not 50 per hr.If you only eat 500 cals a day and burn up that while sleeping,you would disappear.You can google calories burnt with activities,and it will tell you.Good Luck.

Answer 3

'Calories' are a measure of HEAT, so if you are warm, you are 'using' calories. If your surroundings are warm, you will use less calories, because you lose less heat.

Your body temperature varies, and it's lowest in the middle of the night. When you sleep, your activity also varies. Some people always (and others sometimes) move about a lot in their sleep. This burns up more fuel (mostly fat, some sugar), and therefore 'uses' calories.

Because of all the variations, it's impossible to calculate specific relationships between the 'calorific value' of different activities and substances, either on the 'input' side (usually foods), the output side (usually movement, but also things like anxiety, which raises the tension in all your muscles a little bit, so using more fuel overall).

Fitness advice based on 'calories' is general, and is devised by reference to general population tendencies, rather than specific individual responses.

'Basic Metabolic Rate' is a guesstimate (derived from measurements that relate FAIRLY closely to fuel use) of the amount of fuel your body needs to burn in order to just maintain its life, rather than gaining or losing function.

Because this situation NEVER happens (different parts of your body will gain & lose function according to different circumstances; it is normal to be storing AND releasing bodyfat at the same time), calorific equations can only be applied to long-term trends, rather than particular events.

You burn around 50 sleeping, an hour. But you can burn so many more walking, running, working out, doing dishes, vaccuming, etc, etc. I don't think you would lose weight not doing anything except sleeping, though. I think if you ate healthy, though, you would maintain a good weight.

Answer 5

you're burning calories but not for weight loss

yes if you ate 100 calories a day and slept until all of them were burned off you'd have a net loss for the day....but you'd probably be dead in a week or so from malnutrition

the body is an engine...needs fuel

Answer 6

Actually, you're right, you do burn calories while sleeping, but not many. Your metabolism slows while you're sleeping; therefore, don't consider it as a weight loss plan b/c you'll actually gain weight if you sleep alot. In other words, it's being really lazy, and we all know what happens to a lazy person------OBESITY!

Answer 7

yes but the point of calorie counting is too intake proper calories you have to be balanaced the same way you need to intake a certain amount of fat you need carbs etc everything has calories its just better to eat fruit that has cals than chocolate...but burning clas doesnt account for fat so you need to exercise to get rid of that

Answer 8

yes believe it or not this is how my daughter lost her weight she just drank and went back to sleep got up had a wee and went back to sleep shes lost about three stone doing this as she was never awake long enough to bother eating and when you sleep you are not hungry after 18 hours of no food you no longer feel hungry not till you eat again ,and she actually looked good for all that rest ,i was worried that she would get ill but she fine ,,,

Answer 9

it depends on how much muscle your body has. Lift weights and make your body a calorie burning machine. 500 calories a day? your going to hurt your body, eat more and get more exercise.

Answer 10

Yah but u consmes more calories than that can be burnt even while watching TV, which burns more than that done while sleeping.

Answer 11

You definitely "burn calories" wheil sleeping/sitting. Everyone's body has something called a BMR (basal rate of metabolism), it differs from person to person, with people with more muscle having a higher BMR on average, than those with less muscle mass. Basal metabolic rate (BMR) is the amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive state (meaning that the digestive system is inactive, which requires about twelve hours of fasting in humans). The release of energy in this state is sufficient only for the functioning of the vital organs, such as the heart, lungs, brain and the rest of the nervous system, liver, kidneys, sex organs, muscles and skin. BMR decreases with age and with the loss of lean body mass.
BMR is calculated with the The Harris-Benedict equations:
The original equations from Harris and Benedict are:
for men, BMR = 66.4730 + (13.7516 * w) + (5.0033 * s) − (6.7550 * a)
for women, BMR =65.50955 + (9.5634 * w) + (1.8496 * s) − (4.6756 * a) >
w = weight in kilograms
s = stature in centimeters
a = age in years

or
Women: BMR = (4.35 x weight in pounds) + (4.7 x height in inches) - (4.7 x age in years)
Men: BMR = 66 + (6.23 x weight in pounds) + (12.7 x height in inches) - (6.8 x age in years)

Then:
Take this result and multiply it by your activity level (known as the Harris-Benedict equation):
Sedentary: (little or no exercise): BMR x 1.2
Light activity: (moderate exercise or sports 1 to 3 days per week): BMR x 1.375
Moderate activity: (moderate exercise or sports 3 to 5 days per week): BMR x 1.55
Very active: (hard exercise or sports 6 to 7 days per week): BMR x 1.725
Extremely active: (very hard exercise or sports and a physical job, activity or training 2 times per day): BMR x 1.9
