Treating sleep apnoea after weight loss

For the first two months you will be provided free Optifast meal replacement shakes, bar and soups, with the aim to lose at least 5% body weight in this time.

After this, if your sleep apnoea remains, you will be randomly allocated to a Weight Maintenance Program plus free CPAP (sleep apnoea treatment) or a Weight Maintenance Program alone.

The weight loss and weight maintenance program involves free health coaching and weight management delivered by a team of accredited dietitians, exercise physiologists and psychologists. 


This study has been approved by the Sydney Local Health District Research Ethics and Governance Office (Protocol No X17/0039 and HREC/17/RPAH/48).


You may be eligible to participate in this study if you:

  • Are aged 18-65
  • Have sleep apnoea and are not currently using CPAP
  • Are overweight
