Faire des jeûnes de dopamine permet de combattre des comportements de dépendance.

Publisher’s rating: Se priver d’activités agréables n’a pas de réels effets sur le système de la dopamine, qui est un neurotransmetteur essentiel au bon fonctionnement du cerveau.

The review explains that dopamine fasting does not reduce dopamine levels: avoiding pleasurable activities has no real effect on the dopamine system. It says that addressing addictive behaviors is instead about limiting exposure to triggers associated with them, while noting that evidence for the effectiveness of dopamine fasting was still lacking.
