Adherence
Bariatric surgery-induced weight loss (approx 20%) reduces cravings for sweets and fast food, decreases preference for high sucrose concentrations, and lowers the hedonic value of sweetness (shifting from pleasant to unpleasant upon repetitive tasting) in women, with Roux-en-Y gastric bypass (RYGB) showing unique hedonic effects compared to laparoscopic adjustable gastric banding (LAGB).
If you undergo bariatric surgery, expect your cravings for sweets and fast food to decrease significantly, regardless of whether you have gastric bypass or banding. However, gastric bypass may uniquely make sweet foods taste unpleasant after repeated exposure, which could help you stick to a low-calorie diet more easily than banding. This change is driven by weight loss and anatomical changes, not just a smaller stomach.
Weight loss induced by both procedures caused the same decrease in: preferred sucrose concentration (-12 +/- 10%), perceived sweetness of sucrose (-7 +/- 5%), cravings for sweets and fast-foods (-22 +/- 5%), influence of emotions (-27 +/- 5%), and external food cues (-30 +/- 4%) on eating behavior... RYGB, but not LAGB, shifted sweetness palatability from pleasant to unpleasant when repetitively tasting sucrose (P = 0.05).
Why this rating
Randomized controlled trial design with matched weight loss between groups, though limited to women and specific surgical types.
