Higher levels of the satiety hormone leptin are associated with lower salt taste preference during both low-carbohydrate and low-fat diets.
Your body's satiety hormone, leptin, appears to influence how much you prefer salty foods. Higher leptin levels are linked to a lower preference for salt, regardless of whether you are eating low-carb or low-fat. This suggests a biological link between fullness signals and taste preferences.
we did observe a negative association between salt preference and leptin levels during both LC (rs = 0.59; P < 0.01) and LF (rs = -0.47; P < 0.05) dietary period.
Why this rating
Small sample size (n=18) and exploratory nature limit statistical power, though the correlation is statistically significant.
