An editorial in the Canadian Medical Association Journal (CMAJ) says a component of weight loss, in particular for obesity, is sleep. It's not as easy as, well, sleeping, but researchers say proper sleep promotes weight loss.
"The solution is not as simple as 'eat less, move more, sleep more,'" Drs. Jean-Philippe Chaput and Angelo Tremblay wrote in an editorial in the CMAJ last week. "However, an accumulating body of evidence suggests that sleeping habits should not be overlooked when prescribing a weight-reduction program to a patient with obesity."
Data from sleep studies
Chaput and Tremblay did not conduct a study to gain their insight but examined studies on sleep, drawing data gained from multiple sources to arrive at their conclusions. One study showed that after reducing calorie intake, two groups were given different sleep patterns. One group slept 5.5 hours nightly, the other 8.5; the latter group lost the most weight.
"New studies provide evidence that insufficient sleep enhances hedonic (pleasure seeking) stimulus processing in the brain underlying the drive to consume food; thus, insufficient sleep results in increased food intake," the two researchers wrote.
