The Fast Track to Health (or Fast Track) is a 12 month study looking at the effect of two different dietary patterns on health and well being, weight loss and risk factors for heart disease and diabetes.

The diets being compared in this study are an intermittent fast style dietary pattern called Modified Alternate Day Fasting, and a standard care Reduced Calorie plan. At the moment, we do not know which dietary pattern may be the most effective at reducing weight and improving cardiometabolic risk factors. We aim to test this, and understand which aspects of each dietary pattern are acceptable to young people. It may be that both patterns are effective, finding this out is also important so we can offer more choice and help treat young people with weight concerns in the future.

Modified Alternate Day Fasting

This is a very low energy diet for 3 days per week (approximately 25-35% of estimated daily energy needs or 600-700 calories/day) and a standard healthy diet for 4 days per week.

Reduced Calorie Diet:

This is a moderately low energy diet with higher fibre foods

A dietitian will provide each participant with a meal plan and detailed information to support them to follow their plan. The dietitian will ensure each participant’s meal plan is nutritionally adequate for their needs.

Who can participate in the study?

Young people aged 13-17 years with obesity are eligible to participate.

Inclusion Criteria

•      Adolescents aged 13–17 years (inclusive)

•      Obesity (defined as equivalent to adult BMI 30–45 kg/m2, BMI>95th percentile CDC growth charts)

What will the study involve?

All participants will progress through three phases during the study.

Phase 1: Everyone will follow a Very Low Energy Diet to kick-start weight loss for the first 4 weeks. This involves having 3-4 meal replacements and a small meal each day. Meal replacements will be provided free of charge.

Phase 2: Each person will be randomised to receive the intervention. There is not a choice of which pattern to follow.

Phase 3: Everyone will continue to follow the plan they were given in Phase 2, with support from the dietitian. 

Participants are expected to attend 10-13 appointments with a parent/carer at one of the study locations at The Children’s Hospital at Westmead in Sydney, the Be Active Sleep Eat (BASE) Facility at Monash University or Monash Children’s Hospital in Melbourne to meet with the dietitian. Some of the consultations may be via Skype, Facetime or on the phone. Additional support will be provided from a dietitian via text message, email, and phone calls and via social media.

Benefits of participating in the study

The guidance and support the participant will receive from the dietitian may help him/her manage their weight. It is also possible that as a result of following the meal plan and losing weight, the participant’s risk factors for heart disease and diabetes will improve.
