Are you familiar with those late-night snacking sessions that leave you feeling guilty and wondering, “Why did I eat that whole bag of crisps?”
Well, it turns out that your sleep habits might be playing a sneaky role in those calorie-loaded moments.
Yes, poor sleep impacting your food choices has been caught red-handed in scientific investigations! So, grab a cup of coffee (in moderation, of course!) and join us on this exploration into the link between sleep deprivation and increased calorie intake.
The Sleep-Induced Midnight Cravings.
Picture this: It’s late into the evening and you’re readying yourself for bed. Suddenly, a chorus of cravings begins to serenade your senses. “Just a little something before bed” you think to yourself, as your feet are somehow already heading in the direction of the kitchen.
This late night craving isn’t just in your head! Research has shown that sleep deprivation can mess with your hormones, particularly ghrelin and leptin.
Ghrelin, the hunger hormone, increases when you’re sleep-deprived, making you feel hungrier than usual. At the same time, sleep deprivation reduces the levels of leptin, the hormone that signals satiety, leaving you feeling unsatisfied even after a meal.
Sleep deprivation and disrupted hormone levels create the perfect recipe for late-night snacking.
When ghrelin is elevated and leptin is diminished, your body sends signals that it needs to be fed.
Unfortunately, the lack of sleep can lead to poor decision-making; making you more likely to reach for those high-calorie, indulgent treats.
Your body is simply trying to compensate for the sleep it’s lacking by seeking energy-dense foods.
So, the next time you find yourself rummaging through the pantry at midnight, remember that it might be your sleep-deprived hormones playing tricks on you.
The Zombie Food Shopper.
Ever embarked on a grocery shopping trip with less than stellar sleep under your belt?
You may have fallen victim to the sleep-deprived shopper’s curse.
In a study examining simulated online grocery shopping, researchers found that sleep-deprived participants were more likely to fill their virtual carts with unhealthy, calorie-dense items.
It seems that lack of sleep impairs our decision-making abilities and makes us gravitate toward those tempting bags of chips and tubs of ice cream.
When you’re sleep-deprived, your brain can feel like it’s trapped in a fog. The prefrontal cortex, responsible for decision-making and impulse control, becomes compromised.
This foggy state can impair your ability to make mindful choices, leading you to succumb to the allure of calorie-laden treats.
Moreover, sleep deprivation can disrupt the reward centres in your brain, making unhealthy foods appear more enticing. It’s like a double whammy!
So, the next time you’re running on minimal sleep and find yourself mindlessly tossing unhealthy items into your shopping cart, remember that it’s not just your lack of willpower—it’s the sleep-deprived zombie shopper taking control.
The Science of Brain Fog.
Ever experienced those moments when your brain feels like it’s wrapped in a thick fog, and decision-making becomes as challenging as navigating a labyrinth blindfolded?
Well, you can partially blame sleep deprivation for that.
Research has shown that insufficient sleep affects the prefrontal cortex, the part of the brain responsible for executive functions such as decision-making, impulse control, and reasoning.
When we’re sleep-deprived, the prefrontal cortex doesn’t function optimally, leading to a weakened ability to resist unhealthy food choices.
Imagine your brain as a well-oiled machine operating at full capacity after a good night’s sleep. However, when sleep-deprived, it’s like that machine is running on a low battery—sluggish, inefficient, and prone to errors.
You’re more likely to succumb to the allure of those calorie-laden treats because the brain’s ability to consider long-term consequences is compromised.
In simpler terms, sleep deprivation makes it harder to say no to that slice of chocolate cake staring at you from the fridge.
The Sleep-Eat Cycle.
Sleep deprivation and unhealthy food choices can become trapped in a never-ending cycle, much like a dance where each partner fuels the other’s moves.
It all starts with poor sleep disrupting your body’s natural circadian rhythm, the internal clock that regulates various bodily functions, including hunger and satiety.
When this delicate balance is disrupted, imbalances occur in hunger hormones.
Sleep deprivation often leads to an increase in ghrelin, the hormone responsible for stimulating appetite. Higher levels of ghrelin make you feel hungrier than usual, causing those midnight cravings and a heightened desire for food.
On the flip side, sleep deprivation reduces the levels of leptin, the hormone responsible for signalling satiety. With lower levels of leptin, even after a meal, you may still feel unsatisfied, leading to overeating or seeking out more food to fill that void.
What’s interesting is that consuming calorie-dense foods and drinks, especially those high in sugar or alcohol, can further disrupt your sleep. These nutrients can negatively impact sleep quality, making it harder to fall asleep or stay asleep throughout the night.
So, the cycle continues as poor sleep begets unhealthy food choices, and unhealthy food choices further disrupt sleep.
Breaking Free.
Breaking free from this sleep-eat cycle requires a multifaceted approach.
Prioritising good sleep hygiene, such as establishing a consistent sleep schedule, creating a relaxing bedtime routine, and creating a sleep-friendly environment, can help improve the quality and duration of your sleep.
Additionally, making mindful food choices, focusing on a balanced diet with plenty of fruits, vegetables, whole grains, and lean proteins, can support better sleep and overall health.
By nurturing a symbiotic relationship between sleep and nutrition, you can gradually break free from the sleep-eat cycle.
Remember, it’s not just about what happens in the kitchen or the bedroom individually, but how they influence and support each other for a healthier, well-rested you!
Conclusion.
As we bid adieu to our adventure into the world of sleep deprivation and increased calorie intake, let’s remember the importance of a good night’s sleep for both our physical and mental well-being.
While we’ve had some lighthearted fun exploring the subject, it’s essential to recognise that sleep deprivation and unhealthy food choices can have long-term consequences.
So, let’s strive for a peaceful slumber, make conscious food choices, and keep our cravings in check. Remember, a well-rested mind is a wiser, healthier, and happier one!

- Sperry et al. (2018): This study examined the effects of sleep deprivation on food choices and found that sleep-deprived individuals had an increased preference for high-calorie, high-carbohydrate foods compared to well-rested individuals. The researchers also observed changes in brain activity related to reward processing and the regulation of food intake.
- Greer et al. (2013): The study investigated the impact of sleep deprivation on food purchasing behavior in a simulated online grocery shopping task. Sleep-deprived participants were more likely to select unhealthy food items and displayed a stronger preference for calorie-dense foods compared to those who were well-rested.
- St-Onge et al. (2016): This study examined the effects of sleep restriction on dietary intake and found that participants who experienced sleep restriction consumed more calories, particularly from fat, compared to those who had adequate sleep. The sleep-restricted individuals also had higher levels of the hormone ghrelin, which stimulates appetite, and lower levels of the hormone leptin, which signals satiety.
