^aOutliers are defines as 3× larger or smaller than the standard deviation of the mean difference between T0 and T2: body mass index (±5.52 body mass index points): 3 outliers ((1) −5.52; (2) −12.73; (3) −10.56 body mass index points). Portion control behavior (±1.20 points) : 4 outliers

^bAdjusted for baseline body mass index

^cAdjusted for baseline body mass index, age, sex and educational level

^dAdjusted for baseline body mass index, corrected for age, sex and educational level + dieting behavior in the period prior to the measurement
