What this trial studies

This six-month randomized controlled trial at the American University of Beirut Medical Center will randomly assign about 98 perimenopausal women aged 45–55 to either a 16/8 intermittent fasting schedule or to follow Lebanese food-based dietary guidelines. Mental health outcomes will be measured with validated questionnaires and other standardized tools, and group differences will be analyzed using independent t-tests. Key exclusions include current hormone replacement therapy, uncontrolled major medical conditions, current DSM-5 psychiatric diagnoses, dementia, surgical menopause, pregnancy, and non–English speakers. The study aims to determine whether intermittent fasting offers a practical non-pharmacologic approach to improve mood, sleep, and cognitive symptoms during the perimenopausal transition.

Who should consider this trial

Good fit: Women aged 45–55 in perimenopause by STRAW criteria and the Menopausal Rating Scale, who speak English, are not on hormone therapy, and do not have major uncontrolled medical or current formal psychiatric conditions.

Not a fit: Women currently using hormone replacement therapy, with uncontrolled diabetes or other severe medical conditions, with a current DSM-5 psychiatric diagnosis, who have had surgical menopause, or who cannot attend visits at the Beirut center are unlikely to be eligible or to receive benefit from participation.

Why it matters

Potential benefit: If successful, intermittent fasting could provide a non-drug option to reduce mood symptoms, improve sleep, and sharpen thinking for women in perimenopause.

How similar studies have performed: Some small studies in general adult populations suggest intermittent fasting can improve mood and cognition, but its effects specifically in perimenopausal women are largely untested.
