# Here’s How You Burn About 500 Calories While Sleeping

SHARE

To lose weight, the majority of people go on a diet or start practicing sport. However, not many people know that it is not always imperative to drastically change your lifestyle to burn belly fat. On the issue of burning calories, the body is still working while we’re sleeping, so it keeps maintaining life and crucial bodily functions, which means that some people would be able to get rid of up to 500 calories just by sleeping, as Medical News Today claims.

However, when the human body is physically inactive, the metabolic ratio is approximately 15 percent lower than when the person active. To approximate the volume of calories burned, you have to calculate your hourly BMR and multiply it by the number of hours you sleep, and then reduce the sum by 15 percent. BMR is the number of calories the body gets rid of every 24 hours because of primary metabolism.

#### Here’s How You Burn About 500 Calories While Sleeping

Here is the formula you can use:

• Calories burned during sleep = BMR / 24 x numbers of hours sleeping x 0.85

To give you an example, a 40-year old male weighing 195lbs and is 5ft 9” tall will get rid of about 535 calories while sleeping for 8 hours. Here’s the math:

• Calories burned asleep = (1889.07 / 24) x 8 x 0.85
• Calories burned asleep = 78.71 x 8 x 0.85
• Calories burned asleep = 629.68 x 0.85
• Calories burned asleep = 535.23 calories

Another example is a 50-year-old female weighing 160lbs, 5ft 4” tall will burn about 404 calories while on an 8-hour sleep. Here’s the math in this case:

• Calories burned asleep = (1426.3 / 24) x 8 x 0.85
• Calories burned asleep = 59.43 x 8 x 0.85
• Calories burned asleep = 475.43 x 0.85
• Calories burned asleep = 404.12 calories

However, please note that these calculations only offer an approximate number of BMR and calories burned asleep. There are other factors which can influence a person’s BMR such as age, gender, weight, and height.
