Ear zaps to curb cravings? tiny study tests vagus nerve stimulation on appetite and blood sugar
NCT ID NCT07457372
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This small study will test whether a non-invasive device that stimulates the vagus nerve through the ear can affect blood glucose levels, food cravings, and the urge to move in healthy young adults aged 18-35. Eight participants will receive both active and sham stimulation to see if there's a measurable difference. The goal is to understand basic body responses, not to treat any disease.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
transcutaneous auricular vagus nerve stimulation (taVNS) device
What this could lead to
If it works, this could help us understand how the vagus nerve influences appetite and blood sugar, possibly pointing toward new ways to manage cravings or metabolism.
What could go wrong
This is a very small, early feasibility study with only 8 healthy participants, so results may not apply to the general public or people with medical conditions. The stimulation is non-invasive and low-risk, but the study hasn't started yet.
