Understanding Sleep and Its Impact on Appetite and Health

The video explores the relationship between sleep and weight gain, highlighting how sleep deprivation affects appetite-regulating hormones leptin and ghrelin. Lack of sleep decreases leptin, making you feel less full, and increases ghrelin, making you feel hungrier. It also shifts food preferences towards high-calorie, sugary foods. The relationship is bidirectional, as poor diet can worsen sleep quality. Sleep can be a tool for weight regulation and overall health improvement.
