Sleep plays a critical role in overall health, particularly when it comes to weight loss. In this blog, let’s see how sleep impacts your waistline and discuss the practical tips for incorporating better sleep habits. So, from now on, despite how busy your life is, get a good amount of sleep! 

Uh-oh. No compromises on that! 

Science Behind Science and Weight Loss

When you don’t get enough sleep, you lose control over your body. 

There are two hormones- leptin and ghrelin in your body that control your hunger and keep you full. So, with less sleep, you will feel more hungry, even though you just ate a meal fit for the king! This will push you to snack on more, leading to overeating. 

According to the NIH study, Adults who slept five hours or less per night over a workweek gained an average of 3 pounds, and their insulin sensitivity declined. This is because, at night, they had more after-dinner snacks than those who slept for normal hours

According to a clinical study, Adults who increased their sleep hours reduced their calorie intake by an average of 270 calories compared to those who were sleep-deprived. 

Lack of Sleep and Weight Gain: Hormonal Imbalance

Adults with shorter sleep duration are more likely to experience weight gain due to hormonal changes that increase appetite and reduce the feeling of fullness. 

  • Increased Appetite: When you are sleep-deprived, the level of the Leptin and Ghrelin hormones, responsible for satiety and appetite regulation, gets out of order. Leptin, which tells your brain you are full, takes a sudden drop by nearly 16%. Meanwhile, Ghrelin, which makes you hungry, increases by 15%. 
  • Release of stress hormone: When you don’t get enough sleep, your body produces increased cortisol levels, also known as the “stress hormone”, which can stimulate hunger and abdominal fat storage, leading to metabolic dysfunction. 

Metabolism and Sleep

Sleep deprivation decreases the body’s resting metabolic rate, which is the number of calories burned at rest. 

A study found that adults who slept an average of five hours a night over two weeks had a 20% decrease in their metabolic rate. While those who enjoyed a full, solid night’s sleep didn’t experience any decline in metabolic rate. 

Here is how sleep impacts your metabolism,

  • Energy balance: Poor sleep quality impairs your body’s ability to regulate energy balance. It reduces the amount of energy expended during the day while increasing hunger and appetite.
  • Glycogen Storage: When you sleep well, your body maintains adequate glycogen storage for excellent athletic performance and weight management. 

Impact on Food Choices

People who lack adequate sleep often find themselves reaching out for extra snacks late at night. It is because of poor impulse control and decision-making that people make unhealthy food choices. 

  • Altered reward pathways: Sleep deprivation affects the brain’s reward pathways, causing increased food consumption and cravings for high-calorie and unprocessed foods. 
  • Decreased inhibition: A study found that sleep-deprived people experienced brain activity changes that made them less able to make healthy food choices. 

Stress, Sleep and Weight Loss

We already discussed the increased levels of cortisol. Here’s another page on the connection between stress, sleep and weight loss. 

  • Mental Health: Lack of sleep causes stress and anxiety and increases the chance of experiencing depression, which leads to increased calorie intake and weight gain.
  • Visceral Fat: Sleep deprivation and elevated levels of cortisol lead to an increase in visceral fat, the dangerous kind that surrounds major organs and raises the risk of several diseases, including diabetes, heart disease, and cancer. 

Importance of Quality Sleep

Now, let’s talk about quality vs. quantity. 

Your sleeping pattern should be analysed by the number of hours you sleep and how well you sleep. It is not a good slumber if you get eight hours of sleep but are disrupted by frequent awakenings. It will disrupt the natural release of hormones, increase stress levels, and slow down your overall metabolism. 

Hence, you should address issues like sleep disturbances, sleep efficiency, and sleep latency to get better sleep.  Ideally, 7 to 9 hours of sleep is needed.

7 Tips for Incorporating Better Sleep Habits

Here are some tips for incorporating better sleep habits. 

  • Have a sleep schedule: Go to bed and wake up at the same time each day for 21 days, and it will become a habit. Having a sleep schedule regulates your circadian rhythm. 
  • Have a sleep routine: Before sleeping, indulge in relaxing activities like a warm bath, meditation, or listening to soft music. After a few days of this practice, your body will know it’s time to shut down. 
  • Go device-free: Stop using gadgets for at least 30 minutes before going to bed. Screens emit blue light that can interrupt your sleep cycle. 
  • Limit late-night snacking: Do not consume large or heavy meals within three hours of bedtime to ensure proper digestion and reduce disrupted sleep. 
  • Create a comfortable sleeping environment: For good sleep, invest in a comfortable mattress, pillow, and blackout curtains. 
  • Manage stress: Tackle stress through relaxing activities like yoga or muscle relaxation techniques. 
  • Exercise regularly: Regular exercise (yoga, light stretching, and breathing exercises) will make you fall asleep faster and also enhance your sleep quality.
