Lumen is a device that measures your metabolism through your breath. Are you burning fat or carbs? Lumen can tell you through the CO2 you breathe out. Then it gives you advice on how to burn fat more and use carbs to fuel your workout. This is my review of the metabolism tracker along with putting it (and myself) through the ringer. Low carb or keto? I'll show you what metabolic flexibility is and why you're going to think it's pretty darn cool.
