Lumen is among the first of its handheld, portable device and app that helps measure your metabolism in real-time with just your breath, giving a fantastic insight into how efficiently our body optimizes fats and carbohydrates to provide more comprehensive control over your health and wellness.

Making it special, Lumen is the first at-home metabolic tracking accessible outside of research labs for the first time that tracks your metabolism. It helps in decision making to reform the way it approaches weight loss, fitness, and healthy nutrition.

Lumen operates by measuring your body’s carbon dioxide intensity by breathing into a handheld Lumen device, and these levels are calculated through Lumen’s extensive scientific research and development. It also indicates the kind of fuel your body utilizes to produce energy – a mix of fat or carbs.

The device is just like having a nutritionist in your pocket and provides you with personalized suggestions on when and what to eat to fuel your workout based on your metabolism. With Lumen’s daily insights, you can keep track of your metabolism and improve metabolic flexibility: the body’s capability to shift efficiently between utilizing fats or carbohydrates as a source of energy.

The Lumen device is available at and is priced at £299. The device comes with a travel case, charging dock, USB-C Cable, and Premium Customer Support and can be downloaded from the app for free on the Google Play and Apple App Store.
