These studies suggest that sleep affects metabolism by increasing hunger, altering insulin sensitivity, and contributing to weight gain, insulin resistance, and type 2 diabetes, while not significantly impacting energy expenditure.

Sleep plays a crucial role in maintaining metabolic homeostasis. Recent research has increasingly focused on understanding how sleep deprivation and disorders impact various metabolic processes, including energy balance, insulin sensitivity, and hormonal regulation. This synthesis aims to consolidate findings from multiple studies to provide a comprehensive overview of how sleep affects metabolism.
Increased Hunger and Caloric Intake:
Weight Gain and Obesity Risk:
Insulin Sensitivity and Glucose Metabolism:
Energy Expenditure and Metabolic Rate:
Hormonal Imbalance:
Circadian Disruption:
The collective findings from these studies highlight the significant impact of sleep on metabolic health. Sleep restriction and disorders are associated with increased hunger, higher caloric intake, weight gain, decreased insulin sensitivity, and impaired glucose metabolism. Hormonal imbalances and circadian disruptions further exacerbate these metabolic disturbances. Ensuring adequate and quality sleep is essential for maintaining metabolic homeostasis and preventing metabolic diseases such as obesity and diabetes.
