For data entry and analysis, IBM’s Statistical Package for Social Science (SPSS) version 23 (Chicago, IL, USA) was used. For the quantitative data analysis, basic frequencies and percentages and the means and standard deviations were used to describe and compare responses among individuals. Paired t-tests and chi-square tests were used to compare the means at baseline and in the weeks before and after. Repeated analysis of variance measurements was used to investigate the effects of the KD on changes in the anthropometric measurements over time. p < 0.05 was chosen as the statistical significance level [25 (link)].
