Sponsor's own description

Polycystic ovarian syndrome (PCOS) is associated with metabolic symptoms such as hyperinsulinemia. Time-restricted eating may reduce serum insulin and improve insulin resistance in patients with PCOS. Currently, there are few studies investigating time-restricted eating in patients with PCOS. The investigators plan to test the feasibility of time-restricted eating in the management of PCOS by means of a real-world clinical intervention. The investigators will determine if an 18:6 eating protocol reduces insulin levels by means of a randomised controlled crossover trial.
