About

Given the escalating high burdens of overeight and obesity, and related commobidies in Asia, Asian women with overweight/obesity is an important group for targeted intervention in promoting health and wellbeing. A study focused on Asian women at reproductive or early post-menopausal age can inform effective strategies for promoting healthy diet and lifetyle and for optimizing health not only among these women but also for their children and partners.

The Mediterranean diet has beneficial effects on cardiometabolic and reproductive health. So far, evidence on the Mediterranean diet and its health benefits mostly come from Western populations. Studies evaluating health effects of Mediterranean diet in Asian population are scant.

This study aims to investigate the beneficial effects of a healthy, Mediterranean-inspired localized diet (i.e., Asian-Mediterranean diet) on women's health, such as cardiometabolic health with potential mechanisms through modulating gut and brain health.
