Frequently Asked Questions

Lumen is a personalized metabolic health platform. It consists of a handheld breath analysis device and a mobile application designed to measure your metabolism in real-time. By analyzing the carbon dioxide (CO2) concentration in your breath, Lumen determines whether your body is primarily burning carbohydrates or fats for energy. This data provides personalized insights and actionable guidance for nutrition, fitness, and overall wellness, helping you optimize your metabolic health.

The Lumen device is a portable breathalyzer. Users breathe into the device, typically each morning and at key moments throughout the day. It measures the concentration of CO2 in a single exhalation. This measurement indicates your body's current primary fuel source—carbohydrates or fats. This state is known as metabolic flexibility. The result is instantly synced to the Lumen mobile app, which interprets the data to provide a personalized metabolic snapshot and daily recommendations.

The Lumen app serves as the central hub for the user experience. Key features include a Daily Metabolism Score indicating your metabolic flexibility; Customized Nutrition Plans with meal and macronutrient guidance tailored to your goals; Fitness Optimization insights for pre- and post-workout nutrition; Sleep and Metabolism Tracking to analyze the impact of rest on your metabolic rate; and access to Educational Content with science-backed information on metabolism, nutrition, and habit formation.

Lumen is designed for health-conscious individuals, athletes, and anyone seeking a deeper, data-driven understanding of their body's metabolism. It is particularly relevant for those interested in personalized nutrition, biohacking, metabolic flexibility, and moving beyond generic diet plans. Users typically aim for goals such as weight management, improved energy levels, enhanced athletic performance, and overall metabolic health optimization.

Metabolic flexibility refers to the body's ability to efficiently switch between burning carbohydrates and fats for fuel based on availability and demand. Lumen measures this state to provide your daily metabolism score. Achieving metabolic flexibility is associated with benefits such as more stable energy levels, efficient fat burning, improved insulin sensitivity, and better overall metabolic health. The Lumen platform provides personalized guidance to help users develop and maintain this flexibility.
