Abstract

Purpose of Review

Bariatric surgery is currently the most effective treatment for obesity. Roux-en-Y gastric bypass (RYGB) is the most commonly performed bariatric procedure and results in long-term weight loss. Alterations in food preference and choices may contribute to the long-term benefits of RYGB. This manuscript reviews the available literature documenting changes in food preference in both humans and experimental animals after RYGB and discusses the current theory on the underlying mechanisms involved.

Recent Findings

Obesity is associated with an increased preference for sweet and high-fat foods, and the most consistent evidence has been the shift away from these calorie-dense foods in both animal and human studies after RYGB. Self-reporting is the most common method used to record food preferences in humans, while more direct approaches have been used in animal work. This methodological heterogeneity may give rise to inconsistent findings.

Summary

Future studies in humans should focus on direct measures to permit corroboration of mechanistic insights gained from animal studies.

Am J Physiol Regulatory, Integrative Comparative Physiol. 2016;310(10):R952–R9. The study provided a ‘cafeteria diet’ to rats before and after RYGB and saw a decrease in total calorie and percentage calorie from fat intake in comparison to those in the sham surgery group. There was an increase in carbohydrate consumption in the RYGB group when compared to that in the sham surgery group. The study highlighted dietary shifts and found that majority of the calories even after surgery came from food items rich in fat and sugars CrossRefGoogle Scholar
