Statistical methods / analysis
Weight gain tertiles will be compared by non-parametric ANOVA
Baseline correlates of weight gain will be identified by multiple regression analysis. Number of participants was determined by inclusion of all eligible participants who attended the Bariatric Clinic from its commencement in 2012. No statistical analysis was used to determine whether this sample size would achieve study objectives.

Summary
Brief summary
This project aims to determine: 1. Weight loss profiles for patients attend the Royal Melbourne Hospital Obesity clinic. 2. The impact of this weight loss of metabolic parameters such as lipid profile and liver function tests. 3. To determine the impact of this weight loss on Quality of Life Survey results 4. To find factors that predict the occurrence of weight loss in people with obesity who attended the Obesity Clinic.
Hypothesis: Weight loss will be comparable to published data on lifestyle interventions at an average of 5% body weight loss. This weight loss will be variable depending on baseline characteristics such as family history, concurrent mental health issues and low starting motivation being negative predictors for weight loss. Patients who lose weight will show improvement in the metabolic profiles and Quality of Life survey results when compared to those who do not lose weight.
