“…These results led other researchers to investigate the effect of bariatric surgery on food preferences and macronutrient consumption. Halmi's results on RYGB were supported over the years by other short-term studies (34,67,152,161,201,293) and even studies up to 8 yr after RYGB (161). Most of these relied on verbal report.…”

Obesity is an escalating global chronic disease. Bariatric surgery is a very efficacious treatment for obesity and its comorbidities. Alterations to gastrointestinal anatomy during bariatric surgery result in neurological and physiological changes affecting hypothalamic signaling, gut hormones, bile acids, and gut microbiota, which coalesce to exert a profound influence on eating behavior. A thorough understanding of the mechanisms underlying eating behavior is essential in the management of patients after bariatric surgery. Studies investigating candidate mechanisms have expanded dramatically in the last decade. Herein we review the proposed mechanisms governing changes in eating behavior, food intake, and body weight after bariatric surgery. Additive or synergistic effects of both conditioned and unconditioned factors likely account for the complete picture of changes in eating behavior. Considered application of strategies designed to support the underlying principles governing changes in eating behavior holds promise as a means of optimizing responses to surgery and long-term outcomes.

“…Roux‐en‐Y gastric bypass (RYGB) and sleeve gastrectomy (SG) surgery have been associated with changes in food preferences toward less energy‐dense foods . Studies generally report decreased consumption of sugary and fatty foods and increased consumption of fruit and vegetables and protein‐rich foods , although conflicting results exists .…”

Objective Using an ad libitum buffet meal targeting direct behavior, the authors of the current study previously reported no effect of Roux‐en‐Y gastric bypass (RYGB) and sleeve gastrectomy (SG) surgery on food preferences 6 months after surgery. The current study investigated changes in food preferences at 18 months after surgery and whether changes in food preferences at 6 months predicted weight loss. Methods Twenty food items separated into the following food categories were served at the buffet meal: high‐fat, low‐fat, sweet, savory, high‐fat savory, high‐fat sweet, low‐fat savory, and low‐fat sweet. Energy intake and intake from each of the food items were registered. Energy intake prior to the meal was standardized. Results Thirty‐nine subjects completed visits before surgery and 18 months following RYGB (n = 29) and SG (n = 10) surgery. Energy intake decreased 41% (4,470 ± 209 kJ vs. 2,618 ± 209 kJ, P < 0.001), but no change occurred in relative energy intake from any of the food categories (all P ≥ 0.23), energy density (P = 0.20), or macronutrient intake (all P ≥ 0.28). However, changes in high‐fat food intake, protein intake, energy intake, and energy density at 6 months predicted weight loss at 18 months (P ≤ 0.02). Conclusions RYGB surgery and SG surgery do not affect food preferences. However, changes in food preferences seem to be predictive of weight loss.

“…Following a healthy dietary pattern has been associated with less weight regain [ 6 ]. Moreover, eating patterns and food choices were important determinants of weight loss after Roux-en-Y gastric bypass surgery [ 7 ]. Conversely, weight cycling was associated with an elevated fat preference in obese women and female rats [ 8 , 9 ].…”

Neural and Molecular Mechanisms Involved in Controlling the Quality of Feeding Behavior: Diet Selection and Feeding Patterns

We are what we eat. There are three aspects of feeding: what, when, and how much. These aspects represent the quantity (how much) and quality (what and when) of feeding. The quantitative aspect of feeding has been studied extensively, because weight is primarily determined by the balance between caloric intake and expenditure. In contrast, less is known about the mechanisms that regulate the qualitative aspects of feeding, although they also significantly impact the control of weight and health. However, two aspects of feeding quality relevant to weight loss and weight regain are discussed in this review: macronutrient-based diet selection (what) and feeding pattern (when). This review covers the importance of these two factors in controlling weight and health, and the central mechanisms that regulate them. The relatively limited and fragmented knowledge on these topics indicates that we lack an integrated understanding of the qualitative aspects of feeding behavior. To promote better understanding of weight control, research efforts must focus more on the mechanisms that control the quality and quantity of feeding behavior. This understanding will contribute to improving dietary interventions for achieving weight control and for preventing weight regain following weight loss.

Eating patterns and food choice as determinant of weight loss and improvement of metabolic profile after RYGB

Abstract: Participants in the present study appeared to develop a healthier dietary pattern by 6 mo after RYGB. These results show that a healthier dietary pattern is associated with a significant improvement of metabolic profile and weight loss.
