Methodology
Randomized repeated-measures crossover in 51 healthy subjects treated with varying concentrations of Gymnema sylvestre tea or control tea, with gLMS intensity/liking ratings and an ad-libitum sweetness mixing task.
Key Findings
Gymnema reduced sweet intensity perception and liking for sweet foods but increased the desired sucrose content of those foods.
Conclusions
Blunting sweet taste can backfire by driving compensatory demand for more intensely sweet, higher-calorie foods.
Limitations
Acute laboratory paradigm, no measure of free-living intake or body weight.
Supplements Studied
GS treatment diminished sweet intensity perception (p < 0.001), reduced liking for sweet foods (p < 0.001), and increased the desired sucrose content of these foods (p < 0.001).
