Fat-Measuring Breathalyzers

Levl's latest workout companion measures how much fat users are burning by studying how healthy their breath is. This futuristic gadget is equipped with removable tubes that a user can breathe into. Once returned back into their slots, these "breath pods" are studied by Levl's intuitive system, a digital device that will let users know if a specific workout or diet plan they are adhering to is effective in relation to desired goals.

Unveiled at CES 2016 in Las Vegas, Levl measures a user's acetone breath levels and alerts them if they are making a smart choice when it comes to eating or workout habits. While intuitive fitness wearables have made a splash at past CES conferences, this year's workout companions include more conceptual devices that combine scientific and technological capabilities.
