OBJECTIVE: Given the lack of reliable murine model of binge-like eating, we tried
to induce this pathological behavior in mice.
METHOD: We used an experimental protocol mimicking the etiological factors
involved in the development of binge eating in humans, that is, food restriction,
refeeding (R-R) in presence of high palatable food, and stress (S).
RESULTS: Mice subjected to at least three cycles of R-R plus S (forced swimming
stress), showed a binge-like behavior evident as early as 4 h, persisting 24 h
after stress application and not associated to depressive-like behavior. However,
after the third R-R/S cycle, food intakes of mice returned to normal levels.
DISCUSSION: (i) at least three cycles of R-R plus S are required to promote
abnormal eating in mice, (ii) this is not associated to depressive-like
behaviors, and (iii) the enhanced pathological behavior showed a transient nature
not persisting after the third R-R/S cycle.
