How Much Weight Can You Lose By Sleeping

Can Lack Of Sleep Increase Appetite

How to Lose Weight Well | Can you lose weight just by sleeping more?

One common hypothesis about the connection between weight and sleep involves how sleep affects appetite. While we often think of appetite as simply a matter of stomach grumbling, its actually controlled by neurotransmitters, which are chemical messengers that allow neurons to communicate with one another.

The neurotransmitters ghrelin and leptin are thought to be central to appetite. Ghrelin promotes hunger, and leptin contributes to feeling full. The body naturally increases and decreases the levels of these neurotransmitters throughout the day, signaling the need to consume calories.

A lack of sleep may affect the bodys regulation of these neurotransmitters. In one study, men who got 4 hours of sleep had increased ghrelin and decreased leptin compared to those who got 10 hours of sleep. This dysregulation of ghrelin and leptin may lead to increased appetite and diminished feelings of fullness in people who are sleep deprived.

In addition, several studies have also indicated that sleep deprivation affects food preferences. Sleep-deprived individuals tend to choose foods that are high in calories and carbohydrates.

Other hypotheses regarding the connection between sleep and increased appetite involve the bodys endocannabinoid system and orexin, a neurotransmitter targeted by some sleep aids.

A Single Sleep Counseling Intervention Helped People Sleep Longer

For the study, Dr. Tasali recruited 80 adults who were classified as overweight with a body mass index between 25 and 29.9. The group, with an average age of about 30, reported they regularly slept fewer than 6.5 hours per night.

After two weeks of monitoring study participants sleep habits at home via wrist sensors, Tasali and her team divided the group into two categories: a control arm that continued with their regular sleep routine, and a study arm, which received a single one-on-one sleep counseling intervention. During the session, Tasali helped the study participants carve out a personalized sleep plan to work in an hour of extra sleep each night.

Both groups then slept at home for another two weeks with wrist actigraphs recording their sleeping patterns. Seventy percent of those who received sleep counseling had full-time or part-time jobs and for most, changing their sleep habits meant getting into bed earlier each night. Putting away phones, laptops, and other electronic devices before bedtime was another big factor that helped people in this group get that extra hour of sleep each night, Tasali says.

Among the control group, caloric intake increased by about 115 calories per day on average.

About 270 to 300 calories is the equivalent of a McDonalds cheeseburger or a little bit less than the calories in four large eggs.

How The Reward System Works

We have a bag of sweets and eat one. The reward and pleasure centres of our brain tell us that this is good. So we have another because we now know that when we eat this thing, the result is a pleasant sensation .

In a person who has had adequate sleep, at some point another part of the brain will intervene and remind the person that too many sweets are bad for their teeth and waistline. The behaviour is checked and the sweets put away for another time.

In someone who is sleep-deprived, two factors are at play. Signals at the reward centres are amplified. So, when the person eats the sweet, the sensation is more intense and the drive to eat more is increased.

Secondary to this, the prefrontal cortex is dampened. So the signal to stop is weaker. In effect, our willpower is weaker.

In this example, the sleep-deprived person keeps on eating. The end result is a net calorie intake that is much higher for the sleep-deprived person compared to the person who got enough sleep.

Why Do I Lose Weight While I Sleep

The main thing that is changing overnight is the amount of water in your system. Its amazing how much water weighs! A gallon of water weighs 8 pounds, and a pint of water weighs 1 pound . This means that if you drink a 1-liter bottle of soda, you instantly gain 1 kilogram from the water! Thats a big weight change, and it can happen very quickly.

Overnight, there are two processes that cause you to lose water gradually. The first is respiration. Each time you exhale, you lose a little bit of water . The second is transpiration through the skin, also known as sweating. Over the course of a night, both of these processes eliminate quite a bit of water.

Then there is the tradition of using the restroom prior to the morning weigh-in. That process can eliminate up to 1 pound of water.

According to this water information page, the average person eliminates about 1.2 liters of water in urine each day, and also eliminates about 1 liter a day through perspiration and respiration. Thats 2.2 kilograms of weight fluctuation happening throughout the day!

You may have heard that its important to drink about eight glasses of water every day. Respiration, transpiration and urination are the reasons why! See the next page to learn more.

How to Lose Weight Fast: 4 Easy Steps ⢠Health blog

Having spent years studying the relationship between exercise, weight management and health, UCLAs Dr. Christopher B. Cooper, together with a team at the university , carried out research that focused on weight, nutrition, exercise and sleep.

Over 12 weeks, two groups followed the same exercise and nutrition programme, but one also received a behavioural modification programme a major part of which was sleep training. By the end of the study, the group without the additional training had lost on average 1.3 kilograms of fat mass. The group who received the additional training had lost 2.3 kilograms.

Dr. Cooper explains: We were unable to demonstrate that wed improved sleep quality, but intriguingly we improved exercise performance, aerobic quality including oxygen uptake and body composition. We saw significant reductions in the percentage of body fat at the end of the exercise training programme that had incorporated sleep training.

However, says Dr. Cooper, there is still a lot of work to be done in the field. Common sense shows us there has to be a relationship between sleep, weight management, exercise and other aspects of behaviour. Lots of studies in our review articles clearly demonstrate associations, but its a much greater challenge to prove cause and effect. More studies are definitely required.

May Help Moderate Your Appetite

Getting enough sleep may help prevent increases in calorie intake and appetite that can happen when youre sleep deprived.

Many studies have found that people who are sleep deprived report having an increased appetite and a higher daily calorie intake .

In fact, one review of studies found that those who experienced sleep deprivation consumed an additional 385 calories per day, with a greater than usual proportion of calories coming from fat .

Another study showed that sleep deprivation led to significant increases in hunger, food cravings, portion sizes, and chocolate and fat intakes .

The increase in food intake is likely caused partly by the effect of sleep on the hunger hormones ghrelin and leptin.

When you do not get adequate sleep, the body makes more ghrelin and less leptin, leaving you hungry and increasing your appetite .


Poor sleep may increase appetite, likely due to its effect on hormones that signal hunger and fullness.

Improving Sleep And Metabolism

You can make changes to help your body burn more calories while sleeping. Try to keep the room temperature comfortably cool because your metabolism kicks in to raise body temperature. The metabolic rate increases with a minimal drop in room temperature, from 72 degrees to 61 degrees Fahrenheit, according to a report in the European Journal of Clinical Nutrition in April 2002.

Because you’ll support weight loss by getting enough sleep, avoid dietary factors that interfere with restorative sleep, such as alcohol, caffeine and big spicy meals that might cause indigestion. A good night’s sleep also depends on honoring natural sleep-wake cycles. The brain secretes melatonin when it’s dark, which makes you sleepy. As daylight dawns, the amount of melatonin goes down to make you more alert. You’ll have a hard time falling asleep if you have lights on in your room. Blue light emitted from electronics, such as your phone, television, computer or tablet, is especially disruptive.

In addition to regulating your system, drinking 1 to 2 cups of coffee or tea in the morning or over the course of the day will also help you to feel less bloated.XResearch source
  • 2Have a healthy mid-morning snack. While some people grab a sugary or fatty pick-me-up snack in between meals, others opt not to snack. Neither option, however, is conducive to losing weight. If you are a snacker, swap that tempting sugary, salty, or fatty snack, with a healthy snack that will sustain you until lunch.XExpert Source
  • You Lose Some Weight When You Sweat At Night

    Doctor Discusses How Sleeping Can Help You Lose Weight

    If you sleep for eight hours in a row, your body will naturally sweat out 200 milliliters. This is because the body temperature stays within the average range. When temperatures are mild, it is at about 85°F and more, but if it is hot outside or on hotter nights, we produce much more liquid through our pores. This is because evaporation occurs due to higher levels of heat energy released by moonlight hitting our skin, causing us to sweat.

    When this happens, you need water to drink since not having enough fluids can cause headaches, hunger, weakness, dizziness, sluggishness, confusion, memory loss, weight gain, dehydration, and electrolyte imbalance.

    Several factors can influence how much you sweat at night, including diet and exercise. If you just had spicy food, for instanceit is likely your body will lose more water weight as part of the digestion process. It does this to cool off from all those spice molecules seeping into every cell.

    Night sweats could also increase during specific periods such as menopause or disease states like hyperthyroidism. This is where there is too much thyroxine hormone produced by your thyroid gland . So in these circumstances, you lose more than that 200 ml of sweat in just one night.

    So if we are to answer the question, how much weight do you lose through sweating? You will have to convert the 200 ml to grams which is essentially translated to 20 mg.

    Why You Lose Weight Overnight

    While you sleep, your bodys metabolism rate drops about 15%. That means many of your bodys processes that consume energy slows down. While that should technically work against weight loss at night, you might still observe yourself lighter in the morning than the night before.

    Here are a few things that cause you to lose weight overnight:

    Exercise Diet And Sleep

    Some studies have found that eating too close to bedtime can lead to weight gain, though a more important factor seems to be the type of food you eat. If you feel compelled to indulge in a midnight snack, stay away from junk food, and opt for a light and healthy snack instead. As a bonus, a healthier diet, in turn, improves sleep quality.

    Regular exercise and a healthy diet can help you regularize your sleep schedule, improve your muscle-to-fat ratio, and boost your metabolism. Avoid drinking caffeine and alcohol before bed. While caffeine does cause a temporary spike in metabolism, it interferes with sleep and is not an effective weight-loss strategy.

    Creating Healthy Habits To Lose Weight

    If a person wishes to maintain a moderate weight, they need to eat and sleep well.

    However, changing routines and building healthier habits can be challenging, and often people stick with some changes more than others.

    Below are some ideas individuals can use to start making healthier lifestyle choices and habits.

    Create a contract: Writing a weight loss goal down in the form of a contract can help a person understand why they wish to lose weight. For example, they may have a family history of heart disease. The contract can also include details on how they will lose weight, such as running twice a week or batch cooking nutritious meals at the weekend.

    Keep a food diary: Tracking meals throughout the day will help a person better understand what they are eating, so they can make mindful choices, such as choosing frozen yogurt over ice cream.

    Monitor progress: An individual can track their progress and health-related milestones. This does not have to be only weight-related and could also include achievements, such as running for 2 miles without feeling breathless.

    How Many Calories Do You Burn While You Sleep

    As a very approximate number, we burn around 50 calories an hour while we sleep. However, every person burns a different amount of calories during sleep, depending on their personal basal metabolic rate .

    The basal metabolic rate refers to the energy needed for essential functions such as breathing, circulation, temperature regulation, and cellular growth and repair. In most people, the basal metabolic rate accounts for approximately 80% of the total calories burned in a day. The brain itself burns glucose for energy, accounting for about 20% of the calories we consume while at rest.

    Sleep is a time for the body to repair and regenerate. In order to do this more effectively, our body temperature drops, our breathing slows, and our metabolism lowers. On average most people burn about 15% fewer calories while sleeping, compared with their basal metabolic rate during the day.
