First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a sensor worn on eyeglasses that tracks when you eat and sends messages to your smartphone to encourage eating less or eating slower. 43 overweight adults wore the device for one week without any messages, then for two weeks with the messages. The goal was to see if these real-time nudges could reduce total calories and slow down eating pace.

What this could lead to
If it works, this could offer a new, low-effort way to help people reduce how much they eat and eat more slowly, which may support weight management.
What could go wrong
This is a very small, early-phase trial with only 43 participants and no long-term follow-up. The device may be inconvenient or not work well in real-world settings, and results may not apply to everyone.
