Desire for Core Tastes Decreases After Sleeve Gastrectomy: a Single-Center Longitudinal Observational Study with 6-Month Follow-up.

LSG seems to be associated with a rapid and sustained decrease in preferences for all core tastes, detectable already at PO day 6. Preferences for sweet and fatty food undergo the highest decline, whereas preferences of water, red wine, and cigarette remain unchanged. The decrease in salty preference seems to correlate with 6-month %TBWL. Further studies are needed on the long-term impact of taste changes after LSG.
