Lumen is a handheld device designed to improve metabolic health by providing real-time insights into your metabolism. By analyzing the concentration of carbon dioxide in your breath, Lumen determines whether your body is primarily burning fats or carbohydrates for energy. This information helps users understand the impact of their lifestyle choices on their metabolism, allowing for more informed decisions regarding diet and exercise.

The device aims to enhance metabolic flexibility, which is the body's ability to efficiently switch between burning fats and carbohydrates. Improved metabolic flexibility is associated with better weight management, increased energy levels, improved insulin sensitivity, and overall health. Lumen provides personalized lifestyle and nutrition guidance based on your unique metabolic profile, helping you achieve specific health goals such as weight loss, increased energy, and enhanced athletic performance.

Lumen's technology is validated by scientific studies and is comparable in accuracy to traditional metabolic measurement methods. It is suitable for individuals looking to optimize their metabolic health, manage weight, and improve energy levels. However, it is advised that individuals with certain medical conditions consult a healthcare professional before using the device.
