Aim: This study will be a 10 year follow-up of the RCT conducted by this research group, assigned a registration number ACTRN12605000113651, registered 9/08/2005.

Randomisation details: Obese patients were randomized to either the medical or surgical group. The medical arm received treatment with a VLCD plus ongoing individualized care encompassing other obesity drugs as determined and behaviour modification programs. The surgical arm received treatment with the Lap-Band System, a laparoscopic adjustable gastric band.
