A new study shows how calories restriction reduces the risk of sleep apneas and improves sleep quality and reduces the need for medications.
Researchers found that the calorie restriction worked by increasing brain activity in regions of the brain associated with learning and memory and regulating blood pressure.
It also reduced the severity of sleep deprivation, which they believe could be beneficial for people with diabetes.
They also found that it improved the efficiency of a sleep center and improved sleep quality.
“The results are exciting because they suggest that this treatment may be particularly effective in people with sleep apnoea,” said study author Anjali Kumar, a researcher at University College London’s Institute of Neurology.
The results, published today in the journal Science, were preliminary and needed to be replicated, but could provide a valuable tool for researchers in developing treatments for sleep disorders.
“This study was designed to look at a single intervention that has been used successfully for the treatment of sleep disorders and is safe and well tolerated,” said Dr. David Hargreaves, director of the Institute of Sleep Medicine at the University of Southampton.
“We hope that this will provide more evidence to further our understanding of how to use the treatment effectively.”
In the study, participants received either a calorie-restricted diet, a regular diet or a control diet.
The calorie-restriction group consumed 1,000 calories per day and the control group ate the same amount of food without restricting it.
The participants with sleep disorders experienced significant improvements in sleep quality, as well as fewer symptoms of sleep disturbance.
But participants with diabetes had no improvement.
This is the first study to look specifically at calorie restriction, and its results could help scientists to better understand the benefits and risks of the sleep-restricting diet, said study co-author Anjalitha Srinivasan, a research associate at the Institute for Obesity Research.
While calorie restriction improves sleep, it doesn’t have the same impact on weight loss, Srinivaan said.
She said her team was interested in learning more about the effect of calorie restriction on weight management.
“This study will be important in understanding how to develop interventions that can improve weight management,” she said.
Dr. Rajendra Jha, a physician and director of clinical research at the Boston Children’s Hospital and the National Institute of Diabetes and Digestive and Kidney Diseases, agreed that the study was exciting and important.
But he cautioned that there were no conclusive studies yet on the long-term effects of calorie restrictions on obesity and diabetes.
“I am not aware of any evidence that shows a weight loss benefit of calorie reduction,” he said.
“And even if this intervention does improve the weight of obese people, it is still going to be a challenge to get that weight off.”
These are very important questions, but we still need more data to understand how long these interventions might work,” he added.
