Cooling gel could flip the Body's Fat-Burning switch

First seen Aug 06, 2026 · Last updated Aug 07, 2026 · Updated 1 time

Summary

This early trial tests whether applying a menthol gel to the chest can activate brown adipose tissue—the body's heat-generating fat—and increase energy expenditure. Twelve healthy, physically active adults will receive menthol gel, a sham gel, or no gel on separate visits. Researchers will measure resting energy expenditure, skin temperature near the collarbone, and shivering to see if menthol mimics cold exposure and boosts metabolism.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Menthol gel (5% L-menthol) applied to the chest
What this could lead to
If menthol activates brown fat, it could point toward a simple, drug-free way to boost metabolism and aid weight management.
What could go wrong
This is a very early, small trial (12 people) measuring short-term effects, so results may not apply broadly. Menthol may cause skin irritation or fail to activate brown fat as hoped.
