Self-perceived successful weight regulators are less affected by self-regulatory depletion in the domain of eating behavior

• Successful weight regulation is difficult for many in the long term.
• Research investigates what makes successful weight regulators successful.
• A reduced susceptibility to self-regulatory depletion may be one mechanism.
• Exerting self-control led to more cookie consumption compared to a control condition.
• This effect was attenuated for self-reported successful weight regulators.

Weight loss and maintenance goals are highly prevalent in many affluent societies, but many weight regulators are not successful in the long term. Research started to reveal psychological mechanisms that help successful weight regulators in being successful. In the present study, we tested the assumption that these mechanisms facilitate successful self-regulation particularly under conditions of self-regulatory depletion. Participants exerted or did not exert self-control in a first task before engaging in a taste test of a tempting but unhealthy food. Participants who had initially exerted self-control ate more than participants in the control condition. This effect was reduced in self-perceived successful weight regulators as compared to perceived unsuccessful self-regulators. A reduced susceptibility to self-regulatory depletion may be an important contributor to long-term weight regulation success in successful weight regulators.
