Description of intervention(s) / exposure
The intervention includes:
1) A cross-sectional questionnaire to evaluate the cooking skills and diet quality of individuals who previously had a Sleeve Gastrectomy (at least 12 months ago). This questionnaire will be administered at Baseline and at the end of the intervention (minus demographic questions) to measure change in cooking habits and attitudes.
2) The intervention consists of access to 10-weeks of cooking tips to encourage cooking using fresh and basic ingredients delivered via a Closed Facebook group. The research dietitian will post daily healthy cooking tips and recipes specially developed for individuals 12 months post Sleeve Gastrectomy.
At the end of the intervention participants will complete a Post Project Evaluation and this will measure how often participants read the Facebook page posts, level of relevance, usefulness and enjoyment of the intervention.
The research dietitian has 25 years of clinical experience, including 10 years supporting individuals who have had weight loss surgery.

Statistical methods / analysis
In a previous study we recruited 55 participants with a history of weight loss surgery (19% drop out rate). They reported low diet quality measured using the Australian Recommended Food Score (ARFS): mean 34.9 (SD 9.04). This standard deviation (9) was used to calculate the required sample size for comparing two means. 37 participants per group is required to detect a 6 unit difference in ARFS with 80% power at a significance level of 0.05. A further 7 participants per group allows for drop outs (19%). Based on these calculations a total of 88 participants are required.
Data will be analysed using STATA. Descriptive statistics will be used to describe demographic characteristics of participants (age, sex, BMI category, Socio-economic indexes for areas decile, education). Differences in participant characteristics of participants who completed and who did not will be examined using chi-square tests. Statistical comparisons will be performed on the pre and post-intervention scores for food skills, nutrition knowledge and diet quality using paired t-tests for normally distributed variables and Mann-Whitney U-tests for non-normally distributed variables. Differences between groups will be assessed using independent two-sample t tests and one-way ANOVA to assess between group differences (e.g. BMI category, sex, age group) and association with scores for food skills, nutrition knowledge and diet quality. Descriptive statistics will be undertaken to evaluate participant satisfaction with the intervention.

Summary
Brief summary
We previously recruited 506 adults (mean age 38.8 ± 11.8 years; 18% male) who completed a nutrition questionnaire. Included were individuals with different classes of obesity and past weight loss surgery (11%, n=55). The relationship between demographic characteristics, nutrition knowledge, and diet quality were explored. Those with obesity (BMI >30 kg.m-2) had lower levels of nutrition knowledge and those with a BMI >40 kg.m-2 had the lowest diet quality of the BMI groups studied. The lowest diet quality was reported for individuals with past weight loss surgery. Our findings provide evidence that individuals who have undergone weight loss surgery should be targeted for nutrition interventions aimed at assisting in the adoption of higher quality diets. This study aims to evaluate cooking skills and diet quality of individuals who previously had a Sleeve Gastrectomy (at least 12 months ago) using a cross-sectional questionnaire. In addition, to conducting an on-line intervention that encourages cooking from fresh and basic ingredients delivered via a Closed Facebook group. The intervention will consist of healthy cooking tips and recipes specially developed for individuals 12 months post Sleeve Gastrectomy, delivered over 10 weeks.
