Exploring the physiological and psychological determinants of food choices after bariatric surgery

Description :

Bariatric surgery is one of the most effective treatments for obesity, although it sometimes results in weight regain. Furthermore, postoperative changes in dietary choices are associated with greater weight loss. What, then, are the determinants of these postoperative dietary choices?

To find out, this thesis project aims to: (1) explore the associations of food choices with sensory perceptions and food pleasure after bariatric surgery (2) explore the associations of sensory and hedonic determinants of food choices (sensory perceptions, food pleasure) with gastric functions, visceral adiposity and vagal functions in the context of obesity and after bariatric surgery.

Ultimately, this research aims to deepen the understanding of the determinants of food choices before and after bariatric surgery, and thus improve the nutritional management of patients in the perioperative period to maximize their chances of weight loss.
