At the end of this experiment, participants reported on the time
since their last meal (h) and the number of daily weight-loss supplements
taken. Participants’ weight was measured on a digital
scale, and a stadiometer was used to measure height; BMI was also
calculated. Each participant received a funnel debriefing in which
the effectiveness of the manipulation and their ability to guess
the hypotheses were checked. All participants recognized the kind
of pills they took. None expressed any suspicion about the link
between supplement manipulation and the dependent measures
