Abstract
BACKGROUND: The Mediterranean diet (MD) is considered the best dietary approach for patients with metabolic dysfunction-associated steatotic liver disease (MASLD). Recently, time-restricted feeding (TRF) has gained attention for its lifestyle compatibility and health benefits. AIMS: This study aimed to compare the effects of a hypocaloric MD with a 10-h TRF protocol to an unrestricted MD in MASLD patients with overweight/obesity and evaluate differences between early and late TRF. METHODS: This 12-week randomised controlled trial in MASLD patients with overweight/obesity consisted of three groups, all following a hypocaloric Mediterranean-type diet. The control group had no eating time restrictions. The early TRF (eTRF) and late TRF (lTRF) groups had a 10-h eating window, from 8 AM to 6 PM and from 12 PM to 10 PM, respectively. Various health parameters were measured. Compliance was tracked via food diaries, and an 8-week follow-up occurred post-intervention. RESULTS: and insulin resistance, as measured by the Matsuda index, homeostatic model assessment for insulin resistance and fasting glucose-to-insulin ratio, improved in the eTRF group at 12 weeks. CONCLUSIONS: This study corroborates the efficacy of MD in ameliorating cardiometabolic risk factors such as body weight and blood pressure in MASLD patients. The combination with an eTRF protocol may improve glycaemic control (NCT05866744). TRIAL REGISTRATION: The study is registered at clinicaltrials.gov (NCT05866744).
