The Children’s Hospital at Westmead is conducting a study for young people who are above a healthy weight.

The Fast Track to Health study is a 12-month study looking at the effect of two different eating plans on health and wellbeing in young people. We want to find out which plan is the most successful at reducing weight and improving health. We may find that both work well.

We also want to find out which eating plans are acceptable to young people, so we can offer more choice and help young people with weight concerns in the future.

How the trial works

There are three phases to the Fast Track study:

Phase 1

Everyone will follow a Very Low-Energy Diet to jump-start weight loss. This involves having meal replacements each day for 4 weeks. Meal replacements are provided free of charge.

Phase 2

Participants will be randomised to either an Intermittent Energy Restricted dietary pattern (also called the 4:3 plan) or a Reduced Calorie dietary pattern. It is not possible for participants to choose the plan they follow.

Phase 3

Everyone will continue to follow the plan they’ve been given with support from the dietitian.

Additional information

  • Participants will have opportunities to join Facebook groups and phone, SMS or email contact with the dietitian.
  • Fast Track will run for 12 months, so it is really important that you and your adolescent are committed to attending the hospital up to 10-13 times over the 12 month study period.
  • Four of these visits will be longer (one visit is 1-1.5 hours, three visits are 3-3.5 hours). Other visits will take approximately 30-45 minutes.

Screening process

There are several screening processes to go through if you would like your adolescent to be involved. These are designed so we can ensure it is safe and appropriate for them to participate.

To be considered for the trial, you will need to complete the following:

  • two questionnaires related to eating behaviours (e.g. binge eating) and wellbeing (e.g. depression)
  • a blood sugar level test via a finger prick meter
  • a brief assessment by one of the study doctors
  • review of a recent blood test or fasting blood test

Participants need to:

  • be aged 13-17 years
  • be well above a healthy weight
  • have parental, or legal guardian consent
  • independently agree to participate in the study.
  • independently agree to participate in the study.
