Obesity is a major health issue for New Zealanders

Obesity and related chronic diseases are some of the foremost health issues facing New Zealand people, with over two thirds of the adult population now overweight or obese.

Decades of research have shown that most diet/exercise programmes, that result in caloric deficit, should lead to weight loss regardless of the type of diet or physical activity.

How do we best support lifestyle changes?

It would appear that the main challenge is how best to support adherence to lifestyle change.

The SWIFT trial evaluated four support strategies:

  • daily self-weighing
  • regular brief support
  • hunger training
  • dietary self-monitoring with MyFitnessPal

250 overweight adults participated in this trial.

Do outcomes improve if participants choose their plan?

Participants chose which diet and exercise plan suited them best; we believed this pragmatic approach would promote better outcomes.

Options included topical and popular weight-loss strategies such as:

  • intermittent fasting
  • 'paleo'-type diets
  • high intensity interval training
