Adults should sleep at least 7 hours a night for health and well-being, yet more than one-third of American adults fail to get enough sleep.
A new study has shown that short-term low calorie diets can increase sleep quality in adults with obesity.
The study also demonstrates that lack of sleep may prevent weight loss maintenance in adults with obesity and that regular exercise may promote the maintenance of good sleep.
Researchers found that sleep qualityTrusted Source increased by 0.8 global PSQI score points and sleep duration increased by 17 minutes per night after the initial 8-week restricted-calorie diet.
the study, she highlighted that “Weight and sleep are linked – we don’t know which way round ie poor sleep causes weight gain or weight causes poor sleep.”
The first part of the study shows weight loss is associated with improved sleep.” However, she added a note of caution: “But for this part, there was no control group and no randomization.
So it might not have been the weight loss and could have been something else, such as time, being in a study, or eating more fruits and vegetables regardless of weight loss.”
So an association but not causal, such as poor sleep, might lead to eating more in the night, which leads to weight gain, and it’s not the sleep,” she added.
