Study flow diagram. The obesity (OB) and control (NC) groups underwent evaluation including the measurement of taste perception before and after weight loss by the OB group. Four participants from the OB group dropped out due to the following reasons: Unwillingness to follow the program (n = 2), family problems (n = 1), and pregnancy during the 7-month weight loss period (n = 1). Two participants from the NC group were unable to participate in the second evaluation, while the remaining 22 individuals completed the second evaluation.
