Could fat-burning be as easy as taking a breath?
Well, maybe not, but Fortune explains that a company called LEVL has introduced a new device that allows the user to determine how much fat they are burning by analyzing their breath. The device's app will with help to tailor fitness regimens and diets to improve metabolism and more efficiently burn fat.
According to The Verge, the device works by measuring the amount of acetone in a person's breath. Acetone is important because it is a byproduct of the chemical breakdown of fat in the body. More acetone should correlate with a higher fat burn. Although the science is not new, this device allows users access to these readings on their own without being forced to take a trip to the doctor or purchase extremely expensive equipment.
