Each participant reported perceived progress toward weight
reduction following the manipulation. Consumption of snacks in a taste test and choice of sugary drinks
were recorded. The results showed that participants receiving a purported supplement ate more in a taste
task and preferred larger quantities of sugar in their reward drinks than did controls. Mediation analysis
supported that the perception of progress toward weight reduction contributed to the liberating effect.
Using weight-loss supplements may increase perceived progress toward weight reduction but decrease
dietary self-regulation. These thought-provoking findings can serve as a basis for educating the public
about the myth that they are free to feel liberated from the need to regulate their eating when using
weight-loss supplements.
