In a 12-week multicentre randomised trial, adding early, late or self-selected 8-hour time-restricted eating to Mediterranean diet-based usual care reduced MRI-measured hepatic fat within each group, but none of the timings beat usual care or each other, and liver markers and faecal microbiota showed no between-group differences. Larger liver fat reductions tracked with baseline steatosis and with achieving ≥5% weight loss, which more people managed on time-restricted eating than on usual care (41-44% vs 16%).
What it shows: One 12-week randomised trial in adults with overweight or obesity (arms of 49, 49, 52 and 47); the study was not powered for secondary outcomes such as liver markers and microbiota, and follow-up ended at 12 weeks.Study · JHEP Rep
