Shape up for life – a sustainable diet/lifestyle?
To improve metabolic syndrome
by A/Prof Jon Buckley
On behalf of the research teamDr Tahna Pettman, A/Prof. Gary Misan, Dr Alison Coates, Prof. Peter Howe
A bit of background
Overweight & metabolic syndrome becoming increasingly
common;
~60% overweight/obese; ~30% MetS
↑ risk chronic disease (e.g. heart disease, diabetes)
Main contributors:
insufficient physical activity
poor dietary choices
What can we do be done?
First line therapy is lifestyle intervention
Current methods ineffective - problem is increasing
Most lifestyle interventions intensive and highly prescriptive
Unsustainable - most people improve, but only temporarily
Study aim :
Evaluate a non-prescriptive lifestyle program
(diet & physical activity) and determine whether
the health benefits persist
the challenge!
1-year comparison study
Control group received copies of the Australian diet
and physical activity guidelines (usual care)
Intervention group participated in Shape up for Life ©
4 months of lifestyle information sessions
followed by:
8 month follow-up (“Active”)
No follow up (“Passive”)
Shape up for Life © program :: Diet information (not energy restriction),
cooking classes, supermarket tour, food labels
Assisted by provision of healthy foods
- Wholegrain breads (George Weston Foods)
- Wholegrain cereals (Specialty Cereals)
- Peanuts (Peanut Company of Australia)
- Tinned fish (Simplot)
Lifestyle skills
Gym, physical activity info., and group exercise
the program! “ eat this, try it ! ”
who’s up for walkaerobics?!
“ what’s your action plan this
week?”

In summary - Shape Up measures up!
Results comparable to other research studies, but low drop-out:
during Shape up for Life intervention (6%)
by 12 months (8%)
Achieved in a ‘free choice’ environment:
Allowed people to incorporate changes that
fit within their lifestyle
Follow-up important for sustaining change
