About the Challenge

The Wearable Challenge is a 28 day weight-loss accountability challenge where players put money on the line and wear a continuous glucose monitor to track blood glucose levels and determine when they get paid back.

The program is in beta and we're still working out some kinks, but the first cohort held in April was a huge success. Since then, we've had 3 successfull cohorts with a 90% success rate. On average, participants lose 9 lbs during the 28 day challenge.

We're excited to open registrations back up for upcoming cohorts and help even more people reach their goals.

If you have any questions about the program, feel free to get in touch.

Who's behind this?

This is a social experiment started (via tweet) by Justin Mares. We've partnered with Levels Health to help people achieve their health goals through wearable-enabled accountability challenges.
