Higher levels of the satiety hormone GLP-1 are associated with lower salt taste preference specifically following a low-fat diet.
When eating a low-fat diet, higher levels of the gut hormone GLP-1 are associated with a lower preference for salty foods. This suggests that GLP-1 may play a role in modulating salt taste preferences specifically in the context of low-fat eating.

Salt taste preference was also negatively correlated with GLP-1 after the LF diet (rs = -0.61; P < 0.01).
