Weight management devices can give users crucial information on their health and wellness, but Lumen takes it a step further by providing personalized nutrition plans based on information gathered from a breath analyzing device. The device appears similar to a breathalyzer and functions by having users blow into a mouth-piece. After analyzing a user's breath, a companion app will show information like daily carb consumption, as well as meal and snack suggestions.
The whole device functions using Respiratory Exchange Ratio. This is the preferred method for determining metabolic fuel and measures carbon dioxide production and oxygen intake to calculate how much energy is being burned on carbs or fat.
The accompanying app for the breath analyzing device utilizes AI to adapt to personal nutritional patterns and is meant to teach users about their body.
