When pursuing a healthier lifestyle, it can be hard to navigate through the plethora of information out there. At times, facts can intermingle with myths and truths can blur with misconceptions. One often questioned is the interplay between sleep and weight loss. 

In the relentless pursuit of productivity and busting schedules, sleep often takes a backseat when it comes to priority. However maintaining an ideal body weight, or achieving a specific look is typically on the minds of many. So is there any connection between the two? Science says yes, let’s break it down.

The digestion process at night

As each of us falls asleep at night, the digestive system shifts. The parasympathetic nervous system which is responsible for promoting relaxation and digestion, will take precedence over the sympathetic nervous system which dominates during wakefulness. This shift helps the absorption of nutrients and the digestion process to begin. 

When we sleep, the digestive process occurs at a slower pace. The stomach contracts periodically which helps to facilitate the movement of food and gastric juices. The liver and gallbladder release bile into the small intestine which enhances the breakdown of fats. The pancreas secretes enzymes which then break down carbohydrates, proteins, and fats.

Late-night cravings

We have all done it. You start craving a snack or two and you get up out of bed and snack a bit. Harmless right? Well, of course at the moment yes, but over time the effects will start to take place. What effects are these? We will explain. 

When we partake in a late-night snack, a series of physiological responses occur as the body prepares for sleep. When you finally get to bed, the body’s metabolic rate starts to decrease. 

When you consume a late-night snack, the digestive system will gear up to process the incoming nutrients. Due to this, the digestive process extends into the night which affects the quality of sleep. This is because high-fat or heavy meals require more energy and time to digest, leading to discomfort or disrupted sleep patterns. Blood sugar levels can also fluctuate, impacting the release of insulin and glucagon. These influence sleep because it disrupts the circadian rhythm and hormone balance. 

The connection between sleep and weight loss

Sleep plays a critical role in regulating many different physiological processes; these processes include metabolism, hormone secretion, and appetite control. When we get adequate amounts of sleep, our body’s metabolism functions optimally, converting nutrients into energy and supporting the maintenance of a healthy weight. 

Now, for those with sleep deprivation, that balance is disrupted. Sleep loss can lead to alterations in the secretion of hormones. Two specific hormones affected include leptin and ghrelin. Leptin signals when you are full, and ghrelin stimulates hunger. This imbalance of hormones is what prompts an increased appetite, especially for foods high in sugars and calories. This habit can lead to overeating and gaining weight over time. 


We previously mentioned the impact of the release of insulin and glucose and how this occurs due to meals before bed. If this pattern continues, and sleep remains deprived, the body’s ability to process glucose is altered, leading to insulin resistance, and increasing the risk of type 2 diabetes. 

Not to mention a lack of sleep affects energy the next day, which reduces the chances of exercise, thus increasing the risk of weight gain. 

If you struggle to attain sleep each night, consider Relaxium Sleep. Relaxium Sleep is a sleep supplement designed to help you fall asleep faster, stay asleep longer, and wake up feeling more refreshed and alert. 

Why getting adequate sleep is important for weight loss

Obtaining sufficient and restful sleep provides numerous benefits for those on weight loss journeys. Quality sleep supports muscle recovery, which makes it easier to engage in physical activity. The more regular the physical activity, the better your metabolism. 

Adequate amounts of sleep also help to promote mental clarity and emotional well-being. This especially in the areas of stress, reduces the likelihood of emotional eating being triggered.

By fostering mental clarity, emotional resilience, and stress reduction, sleep equips us with the mental tools needed to make mindful dietary choices. Ultimately, embracing adequate sleep as an essential pillar of our weight loss journey empowers us to navigate the complex interplay between physiology, behavior, and well-being, setting the stage for sustainable and holistic transformation.

Bettering sleep each night for long-term health 

If you are pursuing a weight loss journey, alongside diet and exercise you must prioritize sleep. If you struggle to do so, implement a few of these tips into your schedule.

  • Establish a consistent sleep schedule: Go to bed and wake up at the same time each day; this includes weekends. By doing this you can train your body to be ready for bed. 
  • Limit exposure to screens before bed: Technology emits a blue light that interferes with the production of melatonin that helps you to sleep each night. Avoid activating your brain before bed. 
  • Manage stress: Consider practicing stress-reducing techniques to help promote relaxation, this will help to deal with stress that could impact your sleep.
  • Create a comfortable sleep environment: Create a bedroom optimal for sleep. Do this by keeping the room clean, cold, and dark.
