Clinical Trial Summary

To examine the effect of using Lumen on metabolic parameters and anthropometric variables. This will be done from baseline to the end of a 12 weeks intervention in adults with prediabetes..


Clinical Trial Description

A single arm intervention evaluation for 12 weeks (pre-post analysis) was designed for the study. After initial screening of the subjects, they will be familiarized with Lumen and will learn on how to take a measure. After 2 days of using Lumen device at home for acquaintance and calibration, subjects will arrive to the clinic and several baseline measurements will be taken, including blood samples and anthropometric variables. Then, subjects will use Lumen at home and will take a Lumen measurement each day for a period of 12 weeks. Subjects will take a Lumen measurement each morning at fasted state and will get a nutritional plan according to their result. In addition, subjects will be guided to log in the last time they consumed a meal (how long they fasted for), the duration of their sleep, and if they managed to follow the previous day recommendations. Moreover, the Lumen application will encourage the subjects to take more measurement throughout the day, in particular in response to food intake as well as before and after workouts. Lumen coach will remotely support the subjects via Lumen's mobile phone application and will provide clarifications and guidelines if needed based on the Lumen metric. Finally, subjects will return to the clinic for their final assessment which would include taking blood samples and anthropometric variables again.

The study will include 40 subjects the most with a minimal target of 30 subjects. The number of subjects was determined based on power analysis made according to a study evaluating HbA1c levels in prediabetic subjects who received low-carb diet for 12 weeks. ;
