O2 uptake, RQ uses a more invasive method since it targets the tissue compared to RER’s breath analysis.Ĭarbohydrates show the biggest RQ of 1.0, while fats show the lowest at 0.7. Although they measure the same CO2 release vs. Clinicians use this number in calculating the basal metabolic rate. Respiration quotient (RQ) is the volume of carbon dioxide released over the volume of oxygen absorbed during respiration.

Juárez-Oropeza, The Respiratory Exchange Ratio is Associated with Fitness Indicators Both in Trained and Untrained Men: A Possible Application for People with Reduced Exercise Tolerance Clin Med Circ Respirat Pulm Med. Torres-Durán,3 Jaime Romero-Gonzalez, Dieter Mascher, Carlos Posadas-Romero, and Marco A. Lower RER also increases insulin sensitivity and helps in whole-body fat oxidation. On the other hand, a lower RER shows that the body uses fat as an energy source. High RER values indicate a sedate lifestyle, using mostly carbs as an energy source. The respiratory exchange rate (RER) shows the muscle’s capacity to get energy. Instead of spending hundreds of dollars on a single RER test in the hospital, you can now blow your breath for 10 seconds into the device, and voila! You have real-time reading on your mobile app. To establish an individualized meal plan, scientists and engineers at Lumen developed technology to track your metabolic health by analyzing the CO2 levels of your breath. Using machine (device) and AI (app) learning, Lumen combines proper measuring tools for breath measurements, keeping data of your activity and food intake, and using these data to recommend a personalized meal plan to improve your overall health. The developers hope to include a wide range of medical illnesses and diseases in the future and will need an FDA-certification for that. Lumen is a tool designed to provide a personalized nutrition plan to achieve optimal health. Metabolic flexibility allows you to shift from one energy source (fat) to the other (carbs) so you can have a balanced meal every time without skipping on some food you love. 2018 2 Reuben L Smith, Maarten R Soeters, Rob C I Wüst, and Riekelt H Houtkooper, Metabolic Flexibility as an Adaptation to Energy Resources and Requirements in Health and Disease Endocr Rev. Sparks, Ph.D., Metabolic flexibility in health and disease Cell Metab. It tracks your daily metabolism, creates customized meal plans, informs you if you have enough energy to burn during a workout and improve your metabolic flexibility. It’s like having a nutritionist and a lab right in your very own home. It works in tandem with the device, and it gives you real-time reports on your metabolic health. The companion app, Lumen – Metabolism Tracker, is available on Google Play and App Store. Lumen will even give you a personalized nutrition plan to help you better optimize your diet. You can track these metrics throughout the day for accurate readings.Īfter a meal, you can track your body’s response to the specific foods you ate, while in the morning you can see your baseline for the day. Lumen is a metabolism tracker device that works by reading the CO2 concentration in your breath to help you understand how your body works.īy reading your breath, Lumen tells you how your body fared from the food you ate. You may also need to take some short breaths before each measurement session according to the instructions provided by your device’s app or user manual. Most users find that taking measurements first thing in the morning before eating or drinking anything is best for getting reliable results. In general, you will want to use your Lumen tracker at least once per day so that you can monitor patterns in your metabolic status over time and make adjustments as needed.
