Get plenty of sleep

Short sleep, usually defined as fewer than 6–7 hours, has been repeatedly linked to a higher body mass index (BMI) and weight gain. Adults who slept fewer than 7 hours per night had a 41% greater risk of obesity, according to one study of 20 trials involving 300,000 participants. In contrast, those who slept more did not see an increase in obesity (7–9 hours per night)

Overeating may result from sleep deprivation, which is quite common over the holidays. This is because people who get too little sleep often feel more hungry, eat more food, and do less exercise. Limiting your sleep may raise your hunger hormone levels, which will ultimately cause you to consume more calories. Additionally, a reduced metabolism has been linked to sleeplessness. Your circadian rhythm, a biological clock that controls many of your physical activities, may have changed, which could be the cause of this.
