As you sleep, your body burns calories, causing you to lose between 1 to 4 pounds of your weight overnight; this weight loss can be regarded as temporary weight loss because you need to consume fewer calories than you burn to avoid weight gain.
On average, you sweat about 25ml per hour of sleep under temperate conditions (around 85 degrees Fahrenheit). ² If you sleep for an average of eight hours, that's around 200ml of sweat per night. This would equate to a drop in weight of approximately 200g overnight.
First things first: It's totally normal for your weight to fluctuate 1-2kg in a day.
If you are not regular, or your fiber intake has been inconsistent, this can be a reason why you gained weight overnight. Maybe you are backed up and haven't used the restroom yet. Excess waste can make you hold onto more water. Your sleep can play a role in water retention.

In one hour of sleep, most people burn approximately 0.3 calories for every pound of body weight. For example, a 150-pound person would multiply 150 by 0.3 to get 45 calories used in one hour of sleep. After eight hours of sleep, that person has burned 360 calories.
Yes, you can lose 1 kg in a day, but this weight loss may be a combination of fluid loss and waste loss and not the loss of fat.
04/6Water retention
Water retention can make you feel bloated, which may add on to your weight. In the morning our stomach is empty and the body's water is lost through sweat, respiration and urination. Due to these factors, we feel lighter.
“Everyone's weight fluctuates throughout the day, and especially from morning to night,” says dietitian Anne Danahy, MS, RDN. “The average change is 2 to 5 pounds, and it's due to fluid shifts throughout the day.” If you see fluctuations of less than 5 pounds, you needn't worry.
Unintentional weight loss has many different causes. It might be caused by a stressful event like a divorce, losing a job, or the death of a loved one. It can also be caused by malnutrition, a health condition or a combination of things.
“On a day you don't eat for 24 hours, you're guaranteed to be losing a third or half a pound of non-water weight that's mostly from body fat,” Pilon told Global News.
In general, our weight fluctuates throughout the day by 500 grams to 1 kilo. It all depends on when you had your meal or performed intense exercises or if you are menstruating. Your weight be a little lower in the morning as compared to evening and at night and there are several reasons behind this.
Not eating means your body doesn't get the sugars it needs to operate properly. This leads to a process called gluconeogenesis, which also causes the loss of appetite. Gluconeogenesis is your body's way of telling itself that blood glucose levels are too low.
Don't Go to Bed Hungry
While we encourage you to avoid late-night snacking, we also discourage you from going to bed while hungry. Your body constantly needs energy to function, even during sleep. Going to bed without a last meal means your body has less energy to rejuvenate and repair itself.
Short-term tiredness and loss of appetite are not usually a cause for concern. These symptoms may be the result of a minor illness or changes to a person's diet or sleep routine. However, persistent tiredness and loss of appetite may signal an underlying health condition that requires treatment.
It is recommended to sleep for seven to nine hours every day to ensure your body repairs properly and you can prevent obesity. According to the National Sleep Foundation, adults should sleep for seven to nine hours every night. This helps one to wake up refreshed and also lose weight.
Keep Salt at Bay to Stop Water Retention
If it senses too much sodium, you'll retain water to even out the concentration. Minimize your intake of salty snacks and restaurant meals for a day, and you'll lose some water weight overnight.
You should step on the scale first thing in the morning. That's when you'll get your most accurate weight because your body has had the overnight hours to digest and process whatever you ate and drank the day before. And you should try to turn that step into a regular part of your routine.
A cheat day causes some large weight increases, but weight because of water, not fat. Depending on what kind of diet you were on, loading up on carbs on a cheat day can increase your weight noticeably. If you were trying to lose fat, you likely were trying to cut carbohydrates out of your diet.
Since you're not eating or drinking during the night (unless you get the midnight munchies), your body has a chance to remove extra fluids (that's why you pee so much in the morning when you wake up). So weigh yourself in the morning ... after you pee.
