Early Postoperative Exposure to High-Fat Diet Does Not Increase Long-Term Weight Loss or Fat Avoidance After Roux-en-Y Gastric Bypass in Rats

“…It will be important to determine through direct measures whether the food preference shifts described here in rodents are also evident in humans. Recent studies suggest otherwise, but more work needs to be done ( 3 , 13 , 29 , 30 ). Further understanding of the impact of bariatric operations on food preferences will certainly improve preoperative counseling and may help to optimize surgical outcomes ( 51 , 52 ).…”

“…Indeed, recent studies that have applied more direct measures of food intake and choice have found little to any change in food selection or relative macronutrient energy intake ( 3 , 29 ). On the other hand, in an ad libitum buffet meal test setting, administered preoperatively and at 6-month after BS, favorable changes in food preferences can be predicted with the use of a combination of factors, including genetic, psychologic and social patient characteristics ( 30 ). Beyond changes in food preferences, RYGB results also in lower average meal size.…”

Regulation of body weight: Lessons learned from bariatric surgery

“…Besides a reduction in caloric intake, many clinical studies also report changes in food preferences and food choice, as well as in the ‘liking’ and ‘wanting’ of specific nutrients and foods after bariatric surgery [ [130] , [131] , [132] , [133] , [134] , [135] , [136] , [137] ]. Homeostatic mechanisms centering around the hypothalamus have been dominating research in the 20th century, but there is now much interest in the role of hedonic and cognitive brain functions in the controls of food intake and regulation of energy balance [ [138] , [139] , [140] ].…”

Meal Patterns and Food Choices of Female Rats Fed a Cafeteria-Style Diet Are Altered by Gastric Bypass Surgery

“…Patients report feeling less hunger and consuming fewer calories, especially foods high in sugar and fat [4,[12][13][14][15][16][17]. There are also some indications that patients find the taste of these foods less appealing [18][19][20][21][22]. However, while self-reporting methods of measuring food intake have utility, they are vulnerable to mis-reporting, particularly under-reporting and are unlikely to be representative of usual food intake [23][24][25].…”
