Explain why can lack of sleep lead to weight gain?

In short (click here for detailed version)

Lack of sleep disrupts hunger and satiety hormones, increasing appetite and promoting weight gain. Additionally, lack of sleep can lead to a decrease in metabolism, which can also contribute to weight gain.

In detail, for those interested!

Impact on metabolism

Lack of sleep can have a significant impact on metabolism. Studies have shown that lack of sleep can disrupt the normal functioning of metabolism, which can lead to increased weight gain. When we sleep, our body regulates many important metabolic processes. Lack of sleep disrupts these processes, which can lead to changes in how our body stores and uses energy from the food we consume. Indeed, lack of sleep has been associated with a decrease in insulin sensitivity, a hormone that plays a key role in regulating blood sugar and fat metabolism. This decrease in insulin sensitivity can lead to increased blood sugar and promote fat storage, which can contribute to weight gain. Additionally, lack of sleep has been linked to changes in levels of other hormones involved in regulating metabolism, which can also have an impact on weight gain. In summary, lack of sleep can disrupt metabolism in various ways, which can promote weight gain and increase the risk of developing health problems related to obesity.

Regulation of hunger and satiety hormones

Lack of sleep disrupts the regulation of hunger and satiety hormones. Levels of key hormones involved in appetite management are affected by lack of sleep.

Leptin hormone, produced by fat cells, is responsible for suppressing appetite. When individuals lack sleep, leptin levels decrease.

On the other hand, ghrelin hormone, produced by the stomach, stimulates appetite. In cases of lack of sleep, ghrelin levels increase, prompting to eat more.

This hormonal disruption resulting from lack of sleep can lead to imbalances in food intake. People deprived of sleep often have a greater appetite for high-calorie and sugary foods.

Furthermore, lack of sleep can alter the perception of hunger and satiety, which can lead to overeating.

These changes in hunger and satiety hormone regulation may contribute to long-term weight gain in individuals who suffer from regular sleep deprivation.

Changes in eating habits

Lack of sleep can disrupt individuals' eating habits. Several studies have shown that lack of sleep is associated with an increase in the consumption of high-calorie, sugary, and fatty foods. Indeed, the sleep-deprived brain often seeks to compensate by craving comforting and energy-rich foods to quickly boost its functioning. This quest for food can lead to less healthy food choices and overconsumption of calories.

Furthermore, lack of sleep disrupts appetite regulation signals, which can result in an increased sensation of hunger. People who do not get enough sleep tend to feel hunger more often and more intensely, prompting them to eat more. Levels of the hormone leptin, which signals satiety, may also be reduced in cases of sleep deprivation, contributing to an increase in appetite.

Changes in eating habits induced by lack of sleep can therefore promote weight gain. It is essential to consider the impact of the quality and duration of sleep on our eating choices and body weight. Good sleep hygiene, combined with healthy eating habits, is essential to maintain a stable weight and prevent unwanted weight gain.

Increasing feeling of fatigue

When a person lacks sleep, they may experience an increase in the sensation of fatigue. The lack of adequate rest disrupts the optimal functioning of the body and can lead to a decrease in the energy available for daily activities. This increased fatigue can make simple tasks more difficult to perform and can also affect concentration and productivity at work or in studies. Furthermore, the constant feeling of fatigue due to lack of sleep can negatively influence mood and worsen perceived stress by the individual.
