In terms of how closely a Lumen reading reflects actual CO2 excretion and fat vs. carbohydrate catabolism, it’s helpful to break this down into two parts:

1. Accuracy of Reflecting Actual CO2 Excretion:

Since Lumen measures only the CO2 exhaled in your breath (without accounting for oxygen consumption), its readings likely reflect real CO2 excretion with moderate accuracy. While there aren’t many independent studies quantifying this, it’s reasonable to estimate that the device’s ability to capture changes in CO2 production is around 80-90% accurate for this limited measure. This is because exhaled CO2 is relatively easy to measure through breath analysis, though fluctuations from hydration, breathing patterns, or recent meals may affect precision.

2. Accuracy of Reflecting Fat vs. Carbohydrate Catabolism:

Since Lumen doesn’t measure oxygen consumption (which is necessary for full RER calculations), its ability to determine whether you’re burning fats or carbohydrates is more of an estimate. Based on available data and company claims, the accuracy of determining fat vs. carb metabolism trends would likely be around 60-70% when compared to the more accurate methods like indirect calorimetry. Factors such as diet, hydration, and individual metabolic variation can affect this accuracy.

Summary:

• CO2 Excretion Accuracy: Likely 80-90% accurate in reflecting actual CO2 levels in exhaled breath.
• Fat vs. Carb Metabolism Accuracy: Likely 60-70% accurate in reflecting whether you’re burning primarily fats or carbohydrates.

These percentages represent reasonable estimates based on the limitations of breath-only analysis without the full respiratory exchange data.

DON’T BUT THIS PRODUCT – Warning their return policy is not existent if you have even opened the box. If you’re not happy with the readings, too bad. If you have a medical condition (like myself) and cannot get enough breath to complete a reading, too bad. They wont take it back. Again, If you have even opened the box but never used it they wont take it back, No refunds. My readings (when I could even complete a full breath 1 time out of every 6th try) were all over the place. Not accurate and their “studies” are done in house with plenty of bias.
