MORAES, Beatriz Azevedo  and  ALMEIDA, Paola Espósito de Moraes. An interventional proposal for binge eating among individuals who have undergone bariatric surgery. Psicol. teor. prat. [online]. 2018, vol.20, n.3, pp. 329-342. ISSN 1516-3687.

This study's objective was to investigate the effects of providing instructions and token reinforcement in the control of the eating behavior for two women who had undergone bariatric surgery and described a compulsive eating pattern. The design consisted of four phases: 1. baseline, 2. reinforcing correspondence between electronic recording and pictures of meals, 3. composed of two subphases: 3.1. instruction and contingent reinforcement of eating every three hours and 3.2. instructing and reinforcing the preparation and ingestion of a daily portion of palatable food, up to 150 kcal. The results show a decrease in the intervals between meals and an increase in the continuous and limited intake of palatable foods, accompanied by a decrease in the report of compulsive episodes. The results suggest that a decrease in binge eating can be achieved by avoiding food restrictions and intermittent access to palatable foods, as previously reported by experimental studies.

Keywords : palatable foods; bariatric surgery; binge eating; food restriction; behavioral therapy.
