This project explores the lived experience and engagement of Pacific and Māori people with the Buttabean BBM motivation programme. While most people lose weight engaging with BBM, it primarily is not a weight loss programme; rather it aims to provide tools for people to live healthier lives ‘forever’, with the secondary effect of weight reduction. A diverse range of BBM participants, including trainers, will be interviewed about their experiences with BBM, what helped them engage and what were barriers. Their stories will undergo thematic analysis to find common themes, and an understanding of how BBM has impacted on their lives in physical, mental, social, family and spiritual ways. Recruitment will stop once no new themes emerge (data saturation). This knowledge will help inform a subsequent study that will follow a cohort of BBM participants over time, looking at both the impact on their weight and their quality of life.
