Adequate sleep ought to be an important part of weight loss, a scientific commentary has said.
The article, in the Canadian Medical Association Journal, recommended adding slumber into the recommended healthy living mix of exercise and a good diet.
Dr Angelo Tremblay, of Quebec's Laval University, as well as Dr Jean-Phillippe Chaput, of Ottowa's Children's Hospital of Eastern Ontario Research Institute, had recently published research stating that both the quality and total length of time people are asleep predicted the overall fat lost by people taking part in a weight-loss programme.
They said that shedding the pounds is not simply a case of "eat less, move more, sleep more".
However, the international healthcare specialists suggested that an "accumulating body of evidence" points towards the argument that slumber should not be overlooked by doctors who are prescribing obese patients weight-reduction programmes.
"Sleep should be included as part of the lifestyle package that traditionally has focused on diet and physical activity," the doctors declared.
Furthermore, adequate sleep has now been added to the obesity management tools the Canadian Obesity Network provides to physicians.
It is thought that a lack of sleep encourages men and women to eat more food and boosts the number of appetite-regulating hormones within the human body, with significant amounts of evidence supporting this argument.
However, increasing levels of physical activity and restricting calorie intake are still recommended for losing weight.
Obesity can lead to a number of health problems, with the UK's National Health Service highlighting stroke and cancer as some of these.
Other conditions obese people are more likely to suffer from include type two diabetes, heart disease and depression.
Some of the treatments international health insurance customers may be able to receive to help them in weight loss include gastric bypass operations and weight loss surgery, although lifestyle changes are typically recommended.
