Seoul: Want to beat the bulge with minimum effort? The key to losing weight could be as easy as enjoying a long lie in at the weekend, according to new research.
Catching up on lost sleep on your day off can help to keep your weight down, say researchers from South Korea.
Sleep is vital to weight loss, because not getting enough shut-eye can disrupt hormones and metabolism. It’s also known to increase the risk of obesity.
Lead study author Dr Chang-Ho Yun, of the Seoul National University Budang Hospital, told Reuters: “Short sleep, usually causing sleep debt, is common and inevitable in many cases, and is a risk factor for obesity, hypertension, coronary heart disease, as well as mortality.”
Having a lie in may be better than napping because the sleep is deeper and follows the body’s sleep-wake rhythms more closely.
To determine how weekend sleep is related to body weight, the researchers used data from a nationwide survey of more than 2,000 people aged between 19 and 82.
Scientists quizzed participants about their height and weight, weekday and weekend sleep habits, mood and medical conditions.
The team also looked body mass index (BMI) and whether the participants caught up on sleep at the weekends – by sleeping for more hours on weekend nights compared to weekday nights.
