Are Calories Burned While Sleeping Equal To Basal Metabolic Rate
Zhang and associates measured calories burned while sleeping , Total Daily Energy Expenditure , and Resting Metabolic Rate in 18 healthy, pre-menopausal, obese, and non-obese female subjects .
Their ages ranged from 22 years to 45 years.
They took the measurements using a human respiratory chamber.
They reported that SMR decreased continuously during sleep and reached its lowest level in the early hours before the subject awakened in the morning.
They also reported that Sleeping Metabolic Rate tended to be significantly higher than Resting Metabolic Rate at the beginning of the sleep period. But it decreased during the night until it fell to a minimum below RMR in the early hours before waking.
According to the researchers, the rate of decrease of SMR after the beginning of the sleep period increased with increasing body weight and body mass index . Thus, while averages of SMR and RMR were similar, average SMR tended to be lower than RMR in obese subjects but higher than RMR in non-obese subjects.
Seale and Conway measured Overnight Energy Expenditure and BMR of 69 adult subjects in a room-sized indirect calorimeter. They reported that although energy expenditure dropped significantly below BMR during sleep, Overnight Energy Expenditure and BMR were equal.
According to the researchers, energy expenditure dropped significantly below BMR for about 60 minutes during sleep. However, Overnight Energy Expenditure was equal to BMR.
How Your Body Uses Calories While You Sleep
Many people are surprised to discover how many calories we burn while sleeping. Although sleeping requires far less energy than most daytime activities, its still an active period for our brain and certain other bodily functions.
The exact number of calories burned sleeping depends on a complex interplay between sleep, diet, exercise, and other variables. If you are having trouble with weight management or energy levels, an understanding of the factors that influence metabolism may help you regain control of your health.

Calculate How Many Calories Do You Burn While Sleeping
Understanding how many calories do you burn while sleeping is achieved by calculating the BMR. However, Accurate BMR calculation requires specific equipment that determines precisely how much oxygen a person is breathing, inhaling, and exhaling over a certain period.
But using the Harris-Benedict equation, it is possible to get the nearly accurate BMR:
This equation takes a persons sex, age, weight, and height into account.
Females, the formula is:
BMR = 665.1 + ) + ) )
Example :
BMR of 26 year female, height 53 and weight- 165
BMR = 665.1 + + = 1522.8 kcal/day.
Males, the formula is:
BMR = 66.47 + ) + ) )
Example :
BMR of 26 years Male, height 57 and weight- 170
BMR = 66.47 + + = 1790kcal/day
The formula will give the count of how many calories do you burn in a day due to BMR alone.
How Many Calories Burned Sleeping
As a very approximate number, we burn around 50 calories an hour1 while we sleep. However, every person burns a different amount of calories during sleep, depending on their personal basal metabolic rate2 .
Regarding this, How many calories do I need if I sit all day? Active men aged between 14 to 30 need 2,800 to 3,200 calories while sedentary men of the same age group need 2,000 to 2,600 calories. Active men and women above 30 years need 2,000 to 3,000 calories while sedentary men and women above 30 years of age need 1,600 to 2,400 calories.
Do you lose calories when you poop? While you might feel lighter after pooping, youre not actually losing much weight. Whats more, when you lose weight while pooping, youre not losing the weight that really matters. To lose disease-causing body fat, you need to burn more calories than you consume. You can do this by exercising more and eating less.
Do heavier people burn more calories? People who are larger or have more muscle burn more calories, even at rest. Your sex. Men usually have less body fat and more muscle than do women of the same age and weight, which means men burn more calories.
Beside above, How many calories do you naturally burn in a day?

What Factors Affect The Basal Metabolic Rate
The basal metabolic rate varies from person to person depending on a number of factors, only some of which can be changed:

Sleep Affects Weight In More Ways Than Just Nighttime Calorie Burn
While you are burning calories during sleep, there are other important ways that sleep affects what you weigh. When it comes to keeping the pounds in check, both the quality and quantity of your sleep are important.
A constant lack of Zs wreaks havoc on your hunger hormones, upping the amount of the appetite-stimulating ghrelin and decreasing the appetite-suppressing leptin in the body. Consuming calories is one compensatory mechanism for an under slept individual, says MH advisor W. Chris Winter, MD, a neurologist and sleep specialist, and author of sleep books including The Rested Child. In other words, youre prone to eating more. Not only that, but after just one sleepless night, research reveals that youre also prone to specifically eating more calorie-dense and high-fat foods.
Sleep affects other weight-regulating hormones as well. Yes, sleep deprivation, even short term, can result in insulin and glucose imbalances, says Kuljeet Gill, MD, a sleep medicine specialist at Northwestern Medicine Central DuPage Hospital. Lack of sleep can also affect how balanced cortisol and your thyroid hormones are.

How To Calculate Your Calories Burned While Asleep
Calculating your precise basal metabolic rate requires the use of a calorimeter. A calorimeter measures the amount of energy you are consuming by analyzing the oxygen and carbon dioxide being inhaled and expelled from your body.
Usually, people who want to get the most accurate reading of their basal metabolic rate will spend the night in a laboratory, abstain from exercise for 24 hours, fast for 12 hours, and sleep for at least 8 hours prior to the reading. These details are important because digestion and exercise are energy-hungry processes that cause spikes in metabolism. The measurements are then carried out in the morning in a darkened, temperature-controlled setting.
Due to the expensive and complex nature of this test, its not practical for the average person to get one done. However, you can get a rough idea of your basal metabolic rate by using one of several equations. One of the most common is the Harris-Benedict equation, which is based on weight, height, age, and gender:
Male: BMR = 66.5 + +
Female: BMR = 655 + +
The result gives you your basal metabolic rate while awake over a 24-hour-period. To calculate approximately how many calories you burn per hour of sleep, divide the number by 24 to get the hourly rate, then multiply by 0.85 to account for the lower metabolic rate during sleep.
BMI = weight / 2 x 703
Avoid Going To Bed Hungry
Going to bed hungry does more harm than you could ever think. Failure to eat anything makes the body to go into starvation mode. It does this by reducing your metabolism thus conserving calories.
Although grabbing a tiny portion of snacks while hungry is fine, you need to make sure that your choices are healthy. High-fat snacks arent the best choices. Taking a piece of high-fiber cereal that contains skim milk wont add any extra calories.
The most important thing to do if you want to burn calories is to strictly eat something only when hungry. If you are not starving, you need to avoid taking a bedtime snack.

Do Stimulants Affect The Calories Burned While Asleep
Avoid stimulants in the run-up to bedtime.
Nicotine and caffeine take several hours to war off and make it difficult for your body to relax. Drinking alcohol can make you feel sleepy, however, it wont result in a good nights sleep. Often drunker sleep is disrupted and causes you to be dehydrated, both leading to poor quality sleep.
Why Does A Heavier Person Burn More Calories
A calorie is a unit of energy and a heavier body requires more calories to carry out basic physiological functions. This can mean doing absolutely nothing.
Think of it like how a larger vehicle typically uses up more fuel than a smaller one. Weight affects fuel consumption .
But this also means that the heavier person expends more calories in a rested state.
This is also known as metabolic rate or metabolism.
The calculator uses a formula to approximate resting calories burned and then it factors in the duration and activity to guesstimate total calories burned .

Lower The Room Temperature
When youre cold, your body will need to burn more fuel to stay warm. And that fuel is calories. So, the colder it is, the more calories itll get rid of, hence the whole cold water thing earlier.
The best way to do it is to turn the thermostat down to 65 degrees while you sleep, your body will be doing all the work while youre off in dreamland.
Just be sure you dont put on too many clothes to stay warm. Otherwise, the only difference youll see is in your electric bill.
Combine Weight Lifting With Complex Carbs
Everyone says to avoid carbs. And, depending on the diet, they may be justified in saying so. But when you eat good carbs, you keep your muscles active. You have more of the right energy to, again, keep your metabolism fast and furious.
Heres how it goes. Lets say youre eating complex carbs that could be a bowl of whole-grain pasta or oatmeal. Your body breaks those carbs down into sugar to give you energy. If that sugar isnt used, it gets stored as fat.
But if youre lifting weights, the fuel is used as energy to keep going. Bodybuilders take in about 50% more carbs to fuel their workouts, and their metabolism is 14% faster than average.

Factors That Contribute To How Many Calories You Burn Sleeping
Its not clear if there are any lifestyle factors that directly influence how many calories you burn while sleeping that night. This number is based on your resting, or basal, metabolic rate . Your BMR represents the energy needed to keep your body functioning properly what you need to breathe, keep your heart beating, and repair cells, among many other roles. While your BMR is running day or night, as a whole, it accounts forabout 60% of the total calories your body burns in a day.
BMR is higher the more you weigh. People withmore muscle mass also have a higher BMR, as muscle is more metabolically active, so it burns more calories than fat. One of the more efficient ways to build muscle is by lifting weights and eating adequate protein. .
Another thing that can drag down BMR is dieting. When you cut calories in order to lose weight, your body conserves energy to make sure theres enough gas in the tank to take care of organ function. One recommendation is to moderately decrease calories while exercising in order to maintain BMR.
Sleep Better To Burn Extra Calories
We have done the math, and we can tell that one can burn calories anywhere between 200 and 600 calories each night. To increase calorie burning, try sleeping in a cool, calm, and darkroom. Cold Temperature helps to burn more calories to maintain the body temperature.
You can burn the most calories during REM sleep.
If youre struggling to get those seven hours each night, maintain a regular sleep schedule and limit electronic and television use before bed.

Eating Late Doesnt Slow Your Metabolism
Eating before bed may cause a temporary increase in your metabolism through whats called thermogenesis. And dont worry about eating after 8 pm. Foods consumed after this time dont magically make your gain more weight its the mindless snacking that does. That said, eating large meals right before bedtime may make it harder to sleep.
Change The Oil Not The Recipe
No need to give up fried food, just switch your cooking oil to something healthier, likecoconutoil.
Research shows that people who had two tablespoons of coconut oilin their breakfast arent as hungry during lunch, and they have less appetite later in the afternoon.
These two oils are also broken down and absorbed quickly into the body, and they help your metabolism get the job done faster.

Does Rem Sleep Burn More Calories Than Non
Multiple studies confirmed that metabolic rate decreased during sleep and reached its lowest level in the early hours before the subject awakened in the morning.
The decrease in energy expenditure during sleep occurs as the subject moves through the different stages of the sleep cycle.
Fontvieille and associates noted that changes in SMR during sleep were due to different rates of energy expenditure associated with the different sleep stages.
The researchers conducted a study to assess the relationship between EE and sleep stages. The study involved 29 subjets of different ethnicities , gender , age, sex, and weight. Fontvieille and associates used electroencephalographic readings to determine sleep stages and measured EE using indirect calorimetry.
The authors reported that SMR was related to sleep stages. Metabolic rates decreased as subjects progressed through the three stages of non-REM sleep, but peaked during REM sleep .
However, the differences in energy expenditure between the sleep stages were not enough to account for differences in SMR between the subjects. The researchers reported that the differences in SMR between the subjects were due to differences in fat-free mass , fat mass, age, sex, and ethnicity.
Brebbia and Altshuler earlier reported significant differences in energy expenditure between the four stages of sleep, with REM sleep having the highest EE. Energy expenditure decreased as subjects progressed through the non-REM sleep stages .

Estimating Calories Burned Sleeping
Calories burned sleeping are by the fat the best calories burned!!
All you need to do is go to sleep and when you wake in the morning youve already burnt around 500 calories more than youve consumed so far that day. In this article well try to give you an idea of how many calories you burn while asleep.
How To Get More Rem Sleep
We all know that a better nights rest is important for body function, mental health, and even weight loss. More REM sleep can lead to burning extra calories while you sleep. Here are a few tips to improve sleep quality:
- Invest in the best mattress for your needs to promote a more comfortable, deeper nights sleep.
- Keep to a schedule so you go to bed and wake up at the same time every day.
- Exercise 20-30 minutes a day. But dont exercise within a few hours of going to sleep.
- Avoid caffeine in the evening hours.
- Shut off bright lights and digital glow, and put your phone on silent. Dont watch TV in bed. Reading a print book or magazine is much better than scrolling on your phone, tablet, or another device with stimulating blue lights. In a Harvard study, it took participants an average of 10 minutes longer to fall asleep using an e-book reader versus a print book. This is because the light emitted from your screen causes your body to suppress the hormone melatonin, which is vital to falling asleep.
- If you cant get to sleep, dont just lay in bed awake. Move to the couch and read until youre tired.
