Symptom 6. Increased Appetite and Weight Gain: The Hunger Pangs of Sleep Deprivation
Sleep deprivation not only affects our mental and physical well-being but also has a significant impact on our appetite and weight. It is not uncommon for individuals experiencing sleep deprivation to notice an increase in their appetite and a propensity for weight gain. In this section, we delve into the relationship between sleep deprivation, heightened appetite, and the potential consequences for our overall health.
Lack of sleep disrupts the delicate balance of hormones that regulate our appetite, leading to changes in hunger levels and food cravings. Ghrelin, known as the “hunger hormone,” is responsible for stimulating appetite, while leptin, the “satiety hormone,” signals to our brain that we are full. When we don’t get enough sleep, ghrelin levels rise, triggering an increase in hunger, while leptin levels decrease, reducing feelings of satiety.
As a result of these hormonal imbalances, individuals experiencing sleep deprivation often find themselves feeling hungrier and craving calorie-dense foods, particularly those high in carbohydrates and sugars. These cravings can be intense and difficult to resist, leading to a higher consumption of unhealthy, energy-dense foods. This, in turn, contributes to weight gain and an increased risk of developing conditions such as obesity and metabolic disorders.
The relationship between sleep deprivation, increased appetite, and weight gain is further exacerbated by the impact of sleep loss on our body’s metabolism. Insufficient sleep disrupts the body’s ability to process and regulate glucose, leading to impaired insulin sensitivity. This can result in higher blood sugar levels and an increased risk of developing insulin resistance and type 2 diabetes. Additionally, sleep deprivation negatively affects the body’s ability to efficiently use stored fat as an energy source, further promoting weight gain.(6)
