To get an idea of just how impactful sleep is on weight loss, you only have to look at the scientific studies.

There has been loads of research done over the years on how the amount of sleep we get each night directly impacts our ability to lose or gain weight.

These are some of the more interesting finds that prove why sleep is so important if you’re trying to reach a healthy weight.

  • One study found that children and adults who slept for shorter periods were more likely to experience obesity. From the study, 89% of children and 55% of adults analyzed reported obesity that was linked to short sleep cycles and a predeterminer of obesity in the future.
  • A 2013 study took a group of 16 adults and allowed them to have just five hours of sleep for five nights. After the trial period, the participants gained an average of 1.8lbs in this short period, which shows the tremendous potential for serious weight gain over longer periods.
  • A study from 2006 focused on a sample group of 60,000 nurses who were of an average healthy weight and their sleep patterns over 16 years. It was discovered that nurses who slept fewer than five hours a night were 15% more likely to be overweight by the end of the study, compared to the nurses who had their recommended seven hours or more each night.

How Many Calories Do You Burn While Sleeping?

The key to simple weight loss in creating a deficit with calories, so you need to be eating fewer calories than those burned during your everyday activities.

The number of calories that someone burns depends entirely on them, and although things like weight are important, it can also be impacted by gender, hormones, and other lifestyle factors.

Our metabolism is responsible for weight loss and determines how many calories we burn each day.

This process is how our body converts the food we eat into energy which is used for bodily functions, exercise, and daily activities.

Our basal metabolic rate (BMR) is how many calories we burn each day even while doing nothing, which includes our all-important nightly sleep.

Even as we sleep, we lose a specific number of calories each night, thanks to our metabolism.

According to Healthline, someone who weighs 125 pounds will burn around 38 calories an hour, so if you’re getting the recommended seven hours of sleep each night it’s 266 calories.

A person weighing Although it might not sound like a lot, consider that you’re doing nothing at all to burn these off and you’ll see why it’s so important.

What Happens When We Don’t Get Enough Sleep?

We know that getting enough sleep each night can help give our weight loss a boost, but what happens on those nights when we’re not able to hit the recommended hours?

Although having an off night now and then won’t take any serious toll on your health or the number on the scale, repeatedly poor sleep can lead to a range of consequences.

We want unhealthy foods

Waking up tired means you’re more likely to reach for a large latte and a bacon sandwich rather than water and a fruit salad.

Studies have shown that people who haven’t slept enough will reach for foods with increased levels of fat, sugar, and carbohydrates, so you’ll be bound to make unhealthy choices.

Our appetite is increased

When we’re sleep-deprived, two important hunger hormones start to act up, making it hard to resist eating all day long.

Ghrelin is released in the stomach and is at its highest when we’re hungry, and leptin suppresses hunger and is released from fat cells.

Both hormones are impacted when we’re sleep-deprived and lead us to eat a lot more than usual.

We eat more calories

The mere fact that we’re awake for longer means there’s more time for eating, which means we can fit more calories into the day.

A regular sleep schedule of at least seven to nine hours a night means there’s just enough time to eat a healthy number of calories from foods that are good for us.

Our willpower is lacking

Studies have proven that when we don’t get enough sleep, it’s harder for us to make healthy choices.

This means we don’t think about the negative effects of eating donuts or skipping our daily walk because it’s too hard for our brains to resist these bad choices. 

We’re too tired to exercise

The last thing you want to do when you wake up from a poor night’s sleep is to work out.

When you don’t get enough sleep there’s less chance that you’ll want to exercise in the morning and this tiredness will carry throughout the day so you won’t want to do it later either.

The easiest thing we can do to lose weight is to get our sleep schedule on track, but how do we know the magic number for how many hours of sleep we need each night?

Everyone is different with how much sleep they require, but as a general rule, we should be aiming for between seven to nine hours every evening.

According to the Sleep Foundation, each age group requires their own recommended hours of sleep each night.

Keep these figures in mind if you’re trying to come up with a healthy sleep schedule for yourself and your family:

  • Babies – 12 – 15 hours
  • Children: 9 – 11 hours
  • Teenagers: 8-10 hours
  • Adults: 7 – 9 hours
  • Older adults 65+: 7-8 hours

The Benefits of Sleep That Can Affect Your Weight

Making sure you get the recommended number of sleep hours each night might not be easy for everyone, but once you make it part of your routine, you’ll start to see the benefits.

These are just some ways that a good night’s sleep can help you lose weight or maintain it at a healthy level.

Increased energy

The most obvious benefit to sleep is having energy and with a full night’s rest, we’ll be full of it.

This means more energy to prepare healthy foods, cook for ourselves at home and avoid takeout, and get in our daily workout.

Clearer head

Nothing beats the feeling of waking up refreshed and full of energy.

When we enter into our day with a clear head, we’re more likely to make smart decisions, stick to our plans, and treat our bodies with respect.

Stronger willpower

Our minds are stronger when we’re well-rested and it’ll be easier to convince yourself to make healthy choices.

This means you won’t have to talk yourself into sticking to a diet or working out a gym because it’ll be a no-brainer.

Improved mood

Being in a happier mood overall will make it easier to stick with healthy habits, and this can be achieved with a good night’s sleep.

When you’re feeling better mentally that will translate to your physical abilities, so it’s hugely beneficial.
