Fast Track will test two different eating plans on health and well being in young people. We don't know which plan is best at reducing weight and improving health and psychological wellbeing, and this is what we are trying to find out. We may find that both work well. This is also important so we can help young people who want to achieve and maintain a healthy weight in the future.

If I take part in this study, what do I have to do?

People who take part in Fast Track will follow either:

Intermittent Energy Restricted Plan

This means following a very low energy eating plan for 3 days each week (about ¼ of your normal energy needs or 600-700 calories/day), then following a healthy eating plan for the rest of the week.

Reduced Calorie plan

This is a fairly low energy plan with higher fibre foods and is based on the Australian Dietary Guidelines.

The eating plan you will follow will be decided by randomisation. This is like tossing a coin. If it lands on heads, you will follow the Intermittent Energy Restricted plan, and if it lands on tails, you will follow the Reduced Calorie plan. Young people who are part of this study cannot choose which plan to follow.

For both plans, a dietitian will give you a meal plan and loads of support and information to help you along the way and to make sure the plan meets all of your nutritional needs.

There are three parts to Fast Track, if you were to take part you would:

Phase 1: Follow a Very Low Energy Diet to kick-start weight loss for the first 4 weeks. This involves having 3-4 meal replacements, such as shakes, soups or bars, and a small meal every day.

Phase 2: You would then follow either the Intermittent Energy Restricted plan or the Reduced Calorie plan with help from the dietitian.

Phase 3: For the rest of the study you would continue to follow your plan with support from the dietitian.

Visiting the study centre

During the study, you will see the dietitian 10-13 times as well as other health professionals. This will happen at one of the study locations in Westmead in Sydney or Clayton in Melbourne. Some of these meetings can be done by Skype, Facetime or on the phone.

We will also provide extra support by your choice of text message, email, phone calls and private Facebook groups (optional) to help you follow the eating plan.



What are the benefits?

The eating plan and support from the dietitian and other health professionals may help you to manage your weight. It is also possible that by following the plan and losing weight, your risk factors for heart disease and diabetes will improve.
