Description of intervention(s) / exposure
The VLED used in this study will be the Optifast intensive program. This consists of 3 to 5 Optifast shakes (dependent on body weight) daily, in addition to two cups of low-starch vegetables, plus one teaspoon of vegetable oil. A protein target of 0.75g/kg of actual body weight will be achieved through the Optifast shakes, with the addition of Beneprotein supplementation if necessary. The Optifast and Beneprotein will be administered by the dietician and will be provided to the participant for the duration of the study.
The duration of VLED will be from commencement of the study to date of surgery, this will be a maximum of 4 weeks.
A combination of daily food diary and weekly telephone call from the dietician will be used to monitor adherence to the VLED.
