Lack of Sleep Linked to Higher Calorie Intake and Weight Gain
What Happened
Researchers from the University of Colorado Anschutz Medical Campus highlight growing evidence that inadequate sleep may be contributing to rising obesity rates. Studies show that sleep-deprived adults often consume 200-300 extra calories per day, while teenagers, many of whom fail to get the recommended 8-10 hours of sleep, may face increased risks of obesity and metabolic health issues. Experts describe sleep as the "third pillar" of a healthy lifestyle alongside diet and exercise.
Key Takeaways
Poor sleep doesn't just affect mood and productivity. It may also increase hunger, encourage excess calorie intake, reduce physical activity, and contribute to weight gain across all age groups. Researchers argue that improving sleep habits, particularly among teenagers, could become an important tool in tackling obesity and improving long-term metabolic health.
