Would the research project be a good fit for me?

The study might be a good fit for you if you:

  • are aged 18 – 55 years
  • have a high body weight relative to height (Body Mass Index, BMI 25 - 40 kg / m2, you can calculate your BMI here:
  • have access to a computer, tablet (such as an iPad) or smart phone (such as an iPhone) that could run an internet browser (e.g., Google Chrome or Firefox) for at least 1 hour per week
  • are able to read and write English
  • don’t: smoke, have a BMI > 40 kg / m2, take any weight-loss medications (or have taken any weight-loss medications in the past 6 months) or currently use medication which has substantial weight gain as a potential side effect e.g. >20mg of prednisolone

  • have not: lost more than 4.5 kg (10 pounds) during the past 6 months

Will I be paid to take part in the research project?

  • If you finish the study, you will go into a prize draw to win 1 of 3 Coles/Myer group e-gift cards: first prize $200, second prize $150 and third prize $100.

If you decide to take part in the research you would:

  • measure your body weight and height at the beginning of the project
  • complete an online survey at the beginning of the project
  • receive and read emails every 4 weeks for 12 weeks (3 emails). These emails provide nutrition information that might help you to change your dietary behaviours
  • again measure your body weight and complete an online survey at the end of the project
