In a pilot clinical study of participants with prediabetes, Lumen usage significantly improved multiple metabolic parameters, including body weight, % body fat, waist circumference, HbA1c, and triglycerides.
Measure fuel utilization in healthy young adults with the Lumen device
Evaluating the validity of a Lumen device for measuring metabolic fuel utilization in healthy young adults.
The Lumen device is able to detect changes in metabolism due to dietary intake providing real-time metabolic information for users under any circumstances, in agreement with the gold standard for RER measurement.
Test-retest reliability of Lumen and response to carbohydrate ingestion
Measure, evaluate and quantify the test-retest variability (repeatability) and the metabolic response after Oral Glucose Ingestion of the Lumen metabolic measurement in a standardized manner.
The %CO2 measurements using the Lumen device are highly repeatable, exhibiting a good to excellent ICC reliability value. Therefore, this supports the formerly established validity of the Lumen device.
Research partnerships with leading institutions in the scientific community to advance the understanding of metabolism and drive innovation in wellness.
Effect of morning bodyweight interval exercise
Prof. Jenna Gillen and her team are using Lumen at the University of Toronto's Faculty of Kinesiology and Physical Education to study the effects of pre and post breakfast HIIT on postprandial glycemic control, post-exercise fat oxidation and appetite perception in women.
Measuring the gastric effect of slow vs rapid digestion carbs
Prof. Bruce Hamaker and colleagues at Purdue University's Whistler Center for Carbohydrate Research are using Lumen to study the metabolic effects of slow versus rapidly-digested carbohydrates.
Influence of menstrual cycle phase on postprandial substrate oxidation
Prof. Jenna Gillen and her team are using Lumen at the University of Toronto's Faculty of Kinesiology and Physical Education to study the differences in fat oxidation across the menstrual cycle of women.
Time-restricted Feeding to Mitigate Metabolic Impairments during Circadian Misalignment
Josiane Broussard, Assistant Prof. and director of the Sleep and Metabolism Laboratory in the Department of Health and Science, is investigating how avoiding food consumption during the biological night can reduce the impact of circadian misalignment on metabolic homeostasis in adults.
The CO2 concentration is measured using a unique breath maneuver, which is performed by inhaling a fixed volume of air through the Lumen device (dynamic to each individual), holding it for 10 seconds, and exhaling fully.
By measuring the CO2 level with the exhale flow rate, Lumen identifies the source of energy the body is using, carbs or fats.
The science is the same, but with cutting-edge technology
Lumen has been validated in peer-reviewed research to match the gold standard of measuring RER.
