Late Bedtimes Can Lead to Weight Gain
One of the major side effects of poor sleep timing is weight gain. Dr. Sethi explains that when people sleep after midnight, their hunger hormones shift. This affects leptin and ghrelin, two chemicals that control appetite. Ghrelin increases hunger, while leptin helps you feel full. When you sleep too late, ghrelin spikes and leptin drops. That means more cravings and less satisfaction from meals. Late sleepers are also more likely to snack at night, especially on unhealthy foods. This can lead to extra calories and slower metabolism. Studies show that people who sleep earlier tend to have lower body fat and better control over cravings. Aligning your schedule with the best time to go to sleep helps regulate hunger and supports healthier eating habits. Weight management starts with good sleep timing.
