The role of insufficient sleep and circadian misalignment in obesity
How Not Enough Sleep and Body Clock Problems Are Linked to Obesity
AI simplified
Abstract
Insufficient sleep and circadian misalignment may contribute to poor metabolic health and increased weight gain.
- Insufficient sleep is defined as sleeping less than the recommended amount for health benefits.
- Circadian misalignment occurs when individuals are awake and consume food during times when their internal body clock promotes sleep.
- Insufficient sleep and circadian misalignment are linked to changes in appetite hormones, such as ghrelin, leptin, and peptide-YY.
- These factors may affect energy expenditure and influence food intake and choices.
- Millions globally fail to obtain adequate sleep, which is essential for healthy metabolic functions.
- Modern lifestyles, including late-night screen use and shift work, often disrupt sleep patterns and circadian health.
