In observational studies, as self-reported sleep duration declines, the likelihood of weight gain and #obesity increases.
Restricted #sleep leads to an increase in total energy expenditure. Unfortunately, it gets compensated by an increase in #caloric intake (especially coming from #carbohydrates); leading to a net positive energy balance and associated weight gain.
During slow wave sleep (SWS), the #metabolic rate hits its lowest point, along with heart rate and blood pressure. Growth hormone is also secreted during SWS. All these changes are crucial to caloric intake and #weight management.
For those trying to achieve a net negative energy balance for #fat loss, getting optimal sleep (#SWS) is crucial.
