  1. OR Odds ratio, CI Confidence interval, SFA Saturated fatty acid, MUFA Mono-unsaturated fatty acids, PUFA Poly-unsaturated fatty acids. Non-starch carbohydrates: simple sugars. Waist circumference (wc) change was calculated by subtracting the waist at baseline from measurements at follow up; increase in WC was defined if WC was positive or > 0. The percentage of energy from macronutrients divides by 5 to calculate one unit of each macronutrient. Logistic regression analysis was applied for the iso-energetic increase (↑) of 5 unit of percentage of energy from one macronutrient at the expense of another (↓). Models were adjusted for baseline age (continuous), sex (except sex strata), physical activity (low, moderate and high), smoking (former and current smoker/never smoked), education level (> 12 and ≤ 12 years of education), baseline WC and energy intake
