Lay summary
Cognitive health, encompassing abilities of learning, remembering, problem solving, and using information, is vital to individual wellbeing. In Aotearoa, approximately 16 percent of the population over age of 60 experiences cognitive impairments, with prevalence rates varying across ethnicities. Emerging research, including our own, has suggested that intermittent fasting (IF) holds promise in enhancing cognitive functions. Consequently, there is a pressing need for a well-powered randomised controlled trial (RCT) to comprehensively evaluate IF's impacts on cognitive health and overall wellbeing. This activation project aims to assess the feasibility and acceptability of conducting such an RCT, by soliciting feedback from participants involved in our previous pilot study and engaging with members of the community, with particular a focus on the Māori and Pacific communities. This project serves as a critical opportunity to involve key stakeholders at an early stage, ensuring a robust and successful implementation of the planned health intervention.
