Myth-buster
Stevia didn't dull appetite in a 428-person meta-analysis — and researchers couldn't even analyze its effect on calorie intake due to sparse data.
This challenges the common assumption that stevia helps cut calories by suppressing appetite, but because the analysis rests on a small pool of clinical studies and couldn't directly test energy intake, the picture is far from settled.
Stevia is often used as a zero-calorie sweetener in hopes of reducing overall calorie intake by making people feel fuller. This meta-analysis pooled data from 428 adults and found no significant change in appetite scores after consuming stevia. Importantly, there wasn't enough research on actual calorie intake to draw any conclusions, so the effect on energy consumption remains unknown — and the clinical setting of the studies means results may not apply to everyday use.
Where this fits in the evidence
This is among the first studies we've indexed on Stevia for Reduced Energy Intake — treat it as an early signal until more research accumulates.
