PCA loading plot of the dietary variables (total energy intake (MJ/day), carbohydrate (% of energy), protein (% of energy), fat (% of energy), dietary fibre, sugar and starch intake (g/day) and dietary GI (units)) and the effect variable C-peptide (g/24 h) at month 6. ΔBMI is calculated as the BMI change between month 6 and 1. The loading plot illustrates the contribution of each variable to each PC. The first PC explains about 36% of the variation, and the second PC explains about 14% of the variation
