How Lack of Sleep Is Linked to Obesity

Short sleep duration is associated with elevated body mass index (BMI).

• Sleep deprivation may lead to increased food intake and decreased energy expenditure.
• Changes in appetite-regulating hormones, such as leptin and ghrelin, are linked to sleep deprivation.
• Multimedia use, including television and internet, could contribute to sedentary behavior and increased caloric intake.
• Shift work and long working hours may favor weight gain due to their connection with shorter sleep durations.
• Epidemiological, biological, and behavioral evidence supports the link between sleep debt and obesity.
