Statistical analysis
All analyses were intention‐to‐treat (ITT). Pre‐intervention demographic, anthropometric, dietary, and cardiometabolic risk factor measurements were compared for the CR and control groups.The mean percentage macronutrient intake was calculated for each group at baseline, 12 and 24 months. Data and results were visualized using right‐angle mixture triangles (RMTs), the primary tool that has emerged for displaying compositional dietary data in the GFN (Raubenheimer, To visualize how self‐selected dietary composition for each macronutrient changed over time in the CR and control groups, we depict diet composition at baseline, 12 and 24 months as their mean and 95% confidence intervals on RMTs, as well as calculating changes and presenting mean changes in the % from each macronutrient from baseline. To assess whether differences in the macronutrient composition of diet over time, and between groups were statistically significant we used a Bayesian multi‐response generalized linear mixed models (MR‐GLMMs; MCMCglmm package; Hadfield, The effects of self‐selected dietary composition on adherence to CR and cardiometabolic risk factors at 12 and 24 months were evaluated in the CR group only. We used the surface‐based approach common in the GFN, where the outcomes (e.g., adherence) are mapped as response surfaces to the nutritional space of the RMT (Saner et al.,
