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.
