Context Brown Buttabean Motivation (BBM) is a grassroot Pacific-led organisation aiming to reduce obesity amongst Pasifika (Pacific people in Aotearoa New Zealand) and Indigenous Māori, helping them choose a healthy and active life-style for themselves, their children and their wider family. BBM offers a holistic approach to weight loss, recognising that mental health, family and cultural factors all play essential and critical roles in nutrition and physical activity patterns.
