the effect of high-protein and low-calorie diets on sleep quality in individuals with obesity

Obesity, defined as excess body fat, has become a global epidemic, especially in low- and middle-income countries. sleep problems are among the complications faced by obese individuals, although such problems are not very common. previous studies indicate that obese individuals have a significantly greater likelihood of developing insomnia and other sleep disorders. meanwhile, there is growing scientific evidence that diet and sleep may be related, and that weight loss can improve sleep quality and sleep-related indices. in order to improve sleep quality and alleviate sleep disorders, this study examined the effects of weight loss diets on sleep quality in obese individuals. the literature indicates that sleep quality and sleep-related indices are improved by weight loss. compared with a low-fat diet, a very low-carbohydrate diet (vlcd) does not adversely affect cardiovascular risk factors for short-term weight loss. when weight loss is combined with vlcd, obstructive sleep apnea (osa) can be improved.
