Changes in taste perception and eating behavior after bariatric surgery-induced weight loss in women.

ABSTRACT:

Objective

Roux-en-Y gastric bypass (RYGB) surgery causes greater weight loss than laparoscopic adjustable gastric banding (LAGB). We tested the hypothesis that RYGB has weight loss-independent effects on taste perception, which influence eating behavior and contribute to the greater weight loss.

Methods

Subjects were studied before and after ∼20% weight loss induced by RYGB (n = 17) or LAGB (n = 10). The following have been evaluated: taste sensitivity for sweet, salty and savory stimuli, sucrose and monosodium glutamate (MSG) preferences, sweetness palatability, eating behavior, and expression of taste-related genes in biopsies of fungiform papillae.

Results

Weight loss induced by both procedures caused the same decrease in: preferred sucrose concentration (-12 ± 10%
