NEW YORK–() –LumensGarmin® International, Inc., a unit of Garmin Ltd. (NASDAQ: GRMN), have started the second phase of integrating health and activity data from Garmin in addition to metabolic data from the Lumen device and the app.

According to Lumen’s research team, the trend is clear: Garmin users are now optimizing their fitness routine by exercising their metabolism.

“Eating properly is just as important as your exercise routine, whether you’re just starting your fitness journey or training for a triathlon,” said Travis Johnson, global product director for Garmin health. “The combination of real-time metabolic data from Lumens and biometric data from Garmin is a powerful tool that enables you to make informed decisions about how to strengthen your body and achieve your fitness goals faster.”

During the last 3 months of this integration, Garmin users have taken over 11,000 post-workout metabolic measurements. The results of these measurements were very successful as 70% of users switched to burning fat as a fuel source after exercising. This efficient conversion from carbohydrates to fat burning is a key factor in training a flexible metabolism.

Compared to the average user, they exercised 15% longer, fasted and woke 10% more burning fat, and took 18% more steps every day.

“We’re seeing that Garmin users who measure their metabolism with lumens become smarter athletes because they get real-time metabolic feedback on their wrist after a workout. In Phase 2, users can connect their metabolism to Garmin’s Body Battery ™ energy monitoring feature, to optimize their training readiness with the right nutrition, “says Barak Alon, data manager at Lumen.

The feature integration was first launched in November 2020 as a Lumen metabolism measurement app was made available to Garmin users in the Connect IQ ™ Store along with a Health API Integration.

In this second phase of integration, Garmin users can now directly correlate their body battery, heart rate, and exercise to see how well their body is shifting from carbohydrates to fats as a fuel source.

New data metrics now available to Garmin users in their Lumen app include:

  • Body battery

  • Resting heart rate

  • High heart rate

With 1 in 5 Americans Adults who own a wearable device are shifting the future of health tracking to the combined value of nutrition and fitness data. Innovative integrations like Garmin and Lumen are at the forefront of leveraging data and technology to determine which workouts really work for our bodies through real-time metabolic insight and personalization.

Peer review

Working with San Francisco State University, Lumen has validated an ongoing study Introduced in 2020, it demonstrates the validity of Lumen® to detect changes in metabolic fuel use in a manner comparable to a laboratory standard metabolic cart, and gives users the ability to get real-time metabolic information in all circumstances.
