Lack of sleep causes weight gain

Doctors warn that people gain weight due to lack of sleep. Constant sleep deprivation affects the body on multiple fronts: it disrupts hormonal balance, slows metabolism, and triggers stress. Consequently, there's a craving for sweet, fatty, and energy-quickening foods, even if only temporarily. Fatigue extinguishes motivation: the body switches to 'store everything possible' mode and converts food into fat more efficiently than before. 7-9 hours of sleep is not a health enthusiast's life hack, but a basic necessity, the doctor emphasizes.
