Big Fat Liar
Five weeks into the program, several of the clients have yet to make any real dents in their weight-loss goals. To get to the bottom of this trend, Jackie assesses the intensity of everyone at basic training and drops by their houses the next day to follow-up.

Jackie discovers how several members of the group are cheating after bringing a lie detector to group therapy.
