Obesity is considered a major risk factor for many chronic, debilitating and life-threatening diseases. Over the past two decades the prevalence of obesity has more than doubled in New Zealand adults. Obesity is more common in Māori, Pacific and South Asian populations compared with other New Zealanders.

Lifestyle approaches involve combined (eg, food, activity and behavioural based approaches – the FAB approach) rather than single factor approaches to weight loss.  The FAB approach should be the first treatment option for weight loss and sustained for weight maintenance.

Maintaining a healthy body weight requires an environment and society where individuals, families and whanau, and communities are supported to eat well and live physically active lives.
