Description of intervention(s) / exposure
Participation in a cooking program designed by Jamie's Ministry of Food (JMOF) and delivered by The Good Foundation in partnership with Edith Cowan University, from the fully equipped JMOF mobile kitchen at various locations in WA. Participants attended a 1.5 hour hands-on cooking session once a week for seven weeks and were taught basic cooking skills to help people prepare simple, fresh, healthy food quickly and cheaply. Classes were delivered by a trained qualified nutritionist who demonstrated the recipe of the day which participants then cooked for themselves in groups of four to a work station. Each week there was a new Jamie Oliver recipe covering every meal from breakfast and sides to lunch and dinner. Participants were taught knife skills and techniques and how to bring out the best flavours from fresh ingredients. They also learned how to plan and budget to make food go further. The mobile kitchen can accommodate 12 participants, cooking in groups of four with the supervision of one demonstrator and 2 trained interns. Inclusion criteria included all individuals who signed up for the program who were aged 18 years and above and who volunteered for evaluation participation; no other inclusion or exclusion criteria were applied. Subsequent sampling for the intervention group was purposive from the program registration database and was determined by the day of the week the participant had allocated for their class. (i.e. Tuesday, Wednesday, Friday or Saturday)

Comparator / control treatment
Control group subjects were those who met the inclusion criteria (all individuals who signed up for the program who were aged 18 years and above and who volunteered for evaluation participation; no other inclusion or exclusion criteria were applied) and were registered on the program's waitlist with an allocated class on a control day (i.e. Monday or Thursday). Control participants were studied during the six week period leading up to their their participation in the cooking program thereby representing those who had not undergone the intervention. Control T1 was 6 weeks prior and control T2 was one week before the program began.

Other design features
Sampling for the control and intervention groups was purposive from the cooking program registration database. Control group subjects were those who met the inclusion criteria and were waiting to participate in the program and who had selected a class on a control day (i.e. Monday or Thursday). Intervention group subjects were those who met the inclusion criteria and had a place allocation on any other day of the week (Tuesday, Wednesday, Friday or Saturday). Four tiers of participation were offered to participants with increasing levels of involvement from the basic level ; completion of the on-line questionnaire, primary outcome 1: level 2; primary outcome 1, plus secondary outcomes 1 to 6: level 3; primary outcome 1, plus secondary outcomes 1 to 7: and level 4; primary outcome 1 plus secondary outcomes 1 to 8.

Efficacy
Statistical methods / analysis
Using G*Power and based on previous JMOF evaluation studies, the required sample for a mixed-model analysis of variance (ANOVA) design (2 groups, each with 2 time points) to detect a small to medium within-between interaction effect (Cohen’s F = 0.15) at the 5% level of significance and 80% power was 90, or 45 per group. For the analysis of the intervention group across three time points using a repeated-measures ANOVA, the required sample to detect a small to medium within-group effect (Cohen’s F = 0.15) at the same level of significance and power was 73.
The computer software package IBM SPSS Statistics 25 will be used to access the data set and perform the statistical analyses. For the basic on-line evaluation questionnaire general descriptive analyses including frequency data with appropriate plots and cross-tabulations will be used to explore and summarise outcome variables. Continuous demographic and baseline characteristics will be summarised using standard statistics (mean and standard deviation) and non-parametric statistics (medians and inter-quartile ranges) where appropriate. Independent t-test for normally distributed data, and Mann-Whitney U test for non-normal data, will be used to assess differences between the groups. Frequencies and percentages will be reported for categorical variables and Chi-square test will be used to test for differences in proportion between the groups. Primary outcomes (continuous) are participants' skills, attitudes, knowledge, enjoyment and satisfaction of cooking and cooking confidence (self-efficacy), measured using the standard online questionnaire. The magnitude of change both within (IT1 and IT2 and CT1 and CT2 time points) and between the intervention and control groups will be assessed using mixed-model ANOVA. Furthermore, changes within the intervention group will be assessed across three time points IT1, IT2 and IT3 using repeated-measures ANOVA. Specific demographic factors of interest (e.g. gender, age, education) will be adjusted in all models. Results will be deemed significant at the P=0.050 level.
To interpret gut microbiota diversity and to analyse the microbial composition of the gut microbiota, multivariate analysis using a combination of R and PRIMER7 and Permanova+ (PRIMER-E, Plymouth) will be conducted. Principal Coordinates Analysis (PCoA) will be deployed to visualise findings. Whereas, distance-based linear models (DISTLM) and distance-based redundancy analysis (dbRDA) will be used to integrate microbiome findings with other relevant data (i.e. dietary intake) that help explain the relationship between the microbiome findings and other outcomes.

Summary
Brief summary
This study will use a quasi-experimental pre-post design consisting of an intervention group of participants undergoing a 7-week cooking program in Western Australia and a control group comprising of participants from the program wait-list. Intervention participants will be surveyed at three time points: before the start of the cooking program (IT1), on program completion (IT2), and six months after program completion (IT3). The control group will comprise participants from the program wait-list and they will be surveyed at two time points: 5 weeks prior to program commencement (CT1) and on entry to the program (CT2). Jamie's Ministry of Food (JMOF) Australia is a community-based program teaching basic cooking skills to help people prepare simple, fresh, healthy food quickly and cheaply. The program involves a 7-week mobile kitchen program that is inclusive for any members of the community who are 18 years and over. This study aims to evaluate the immediate impacts and longer term outcomes of the program in Western Australia and whether this impacts participants' physical health and well-being and chronic disease. risk. Therefore, the ultimate aim of this project is to help combat the rise in obesity and diet-related diseases in Western Australia. The primary evaluation aims to determine whether the program improves individuals' cooking confidence and cooking and eating behaviours (self-efficacy). The secondary evaluation aims to determine whether this impacts lifestyle and biomarkers of chronic disease risk.
The study hypothesises that participation in a program to develop basic cooking skills and nutrition knowledge will impact physiological and mental health and well-being and the underlying mechanisms that lead to positive health.
