Cluster analysis as a tool for analysing dietary data from intervention trials
Baseline diets are rarely the focus of dietary interventions, but this analysis demonstrates they may be relevant in weight loss success. Cluster analysis performed at baseline may be useful prior to assigning participants to groups within an intervention, as the baseline diet, with high intakes of non-core foods and drinks (Cluster 2) allowed participants to reduce their kilojoule intake more than others (Cluster 1) who were closer to dietary guidelines. Cluster 2 subsequently went on to lose more weight.
