30 Pounds Down, 30 more to Go! I’ve been using the Lumen for a year now. I had been reading about the science for 3-years and was fascinated with the science behind CO2 readings rather than what a Glucose Monitor can do. My first 3-weeks into it, my readings went from burning a mix of fat/carbs, ALL carbs, to FAT BURN, and mostly fat. Why? Because I learned what foods worked for my body to get there. I discovered my body NEEDS carbohydrates to get INTO fat burn. Over the past year, I have released 30 pounds. I have now coupled my LUMEN with a GLP1 called Semiglutide (Ozempic, Rybelsus) Tirzepatide (Mounjaro). Nutrition Support at LUMEN has been fabulous in helping me keep my Macros where they need to be for the highest success! The App. Is incredible, menus to follow, the tracking, and support are incredible. Thank You LUMEN for the huge success!
