The sample was comprised of sixteen adolescents (age range:12e18; mean age: 13.94; standard deviation: 1.65; twelve females; all right handed) with excess weight according to the criteria of the International Obesity Task Force (IOTF) (Cole & Lobstein, 2012). This is a subsample of participants from a previously published intervention study in which fMRI was conducted prior to and following the weight loss intervention (Delgado-Rico et al., 2012). The sample size of the present study was calculated to detect weight loss changes associated with the intervention. The present study introduces for the first time the longitudinal imaging component of this larger study.
