The Lumen device has been scientifically validated as a method of assessing changes in metabolic fuel usage.
Two external and independent studies conducted at Tel-Aviv Sourasky Medical Center and San Francisco State University conclude the Lumen device's ability to accurately measure the metabolic fuel usage of an individual as compared to the gold standard for RQ.
The external studies conclude that the Lumen index highly correlates with changes in the RQ of a subject as compared to the gold standard for RQ measurement using indirect measurement with a calorimetric cart.
