What the trial is, and whether it could suit you
Obstructive sleep apnea (OSA) is a highly prevalent disorder that is associated with both cardiovascular and metabolic dysfunction, such as hypertension, increased blood glucose levels and diabetes, obesity, and nonalcoholic fatty liver. While continuous positive airway pressure (CPAP), the best available OSA treatment, has been shown to improve blood pressure in OSA, it does not appear to improve metabolic consequences of OSA, and other therapies for OSA-induced dysmetabolism are needed. Animal models of time restricted eating (TRE) demonstrate an improvement in glucose and lipid metabolism, even in the absence of a reduction of caloric intake. Some human studies have shown an improvement in metabolic dysfunction with TRE, though further well-designed studies are needed. The effects of TRE on metabolic dysfunction in patients with OSA, a population with a high predisposition to metaboli
