A recent study conducted by researchers at the Johns Hopkins University School of Medicine found that losing weight, especially belly fat can result in better quality sleep.
Sleeping and gaining weight has been a well-known fact. However, another link between sleeping and weight loss has been found. Researchers at Johns Hopkins University School of Medicine reported at the 2012 American Heart Association Scientific Sessions in Los Angeles that losing weight could be the key to getting better and undisturbed sleep at night.
"We found that improvement in sleep quality was significantly associated with overall weight loss, especially belly fat," said Kerry Stewart, Ed.D., professor of medicine at the Johns Hopkins University School of Medicine and director of clinical and research exercise physiology.
The study took place during a span of six months where researchers observed the link between sleep ad losing weight on 77 participants who were obese and suffered from Type 2 diabetes or prediabetes. The participants were asked to fill out a form discussing their sleeping problems which included sleep apnea, fatigue, insomnia, restless sleep, excessive sleep and use of sedative.
The individuals were then divided into two groups. One group followed a weight loss program while the other group was set on a simple diet plan. After six months, it was found that both groups lost an average of 6.8 kgs and saw a 15 percent reduction in belly fat. This led to the experience of better quality of sleep.
"The key ingredient for improved sleep quality from our study was a reduction in overall body fat and, in particular, belly fat, which was true no matter the age or gender of the participants or whether the weight loss came from diet alone or diet plus exercise," said study author Kerry Stewart, a professor of medicine at John Hopkins in a statement.
