Brief summary
The purpose of this study is to assess the effect of the pre-operative very low energy diet on liver function tests and weight loss, and to correlate these outcomes with compliance to the program. Our hypotheses are: 1. Pre-operative weight loss will be associated with an improvement in liver function tests 2. Increased compliance to the program will be associated with greater weight loss
