The Canadian Medical Association Journal says although calorie restriction and increased physical activity are recommended for weight loss, there is significant evidence inadequate sleep is contributing to obesity. Lack of sleep increases the stimulus to consume more food and increases appetite-regulating hormones.
Researchers say “the solution [to weight loss] is not as simple as eat less, move more, sleep more. However, an accumulating body of evidence suggests sleeping habits should not be overlooked when prescribing a weight-reduction program to a patient with obesity.
Sleep should be included as part of the lifestyle package that traditionally has focused on diet and physical activity.” They say total sleep time and quality of sleep predicted the loss of fat in people enrolled in a weight loss programme.
