New Device Measures Fat Not Weight

A new breath technology device from LEVL is set to demystify the science of fat loss, giving consumers individualized metabolic information previously only available in a clinical setting. By measuring the amount of acetone in an individual’s breath, LEVL is able to tell whether a user is in a fat-burning state and provide him or her with real-time information needed to modify diet and exercise. 

“It’s time to change the conversation from one about weight loss to one about fat loss.  We have relied for too many years on the number on the scale, but that doesn’t tell the whole story. Every individual needs to have a clear picture of what’s happening inside their body to come up with the right plan to optimize his or her diet and fitness,” said Brad Root, Founder and President of LEVL. “With LEVL, users can understand their body’s metabolic state and make plans based on what will work for them. Because now, the body’s fat burning state can be measured in one breath.”

When the body is burning fat for energy, it is in a state called ketosis. During ketosis, the body generates molecules called ketone bodies, one of which is acetone. Because of its small size, acetone appears in our exhaled breath. Increases in breath acetone indicate increases in the amount of fat burn. That’s where LEVL comes in.

LEVL’s proprietary nanosensor measures the users’ acetone concentration and is converted into fat burn by the LEVL device, all without ever stepping on a scale. Users simply blow into the tabletop device, which draws on 50 years of breath science research, and LEVL’s sensor measures the concentration of acetone in that breath, providing an individual LEVL score.  The LEVL score appears on the device, and LEVL can seamlessly and immediately connect this information to an app on the users’ mobile device to provide them with real-time, predictive information. Users can compare their LEVL score with their diet and exercise choices to adjust their routine to maximize fat loss.  

 “In the world of fat loss, there’s no miracle pill, no one-size-fits-all solution,” said Liz Josefsberg, Health and Wellness Expert at LEVL. “Every body and every body’s metabolism is unique. LEVL is unlocking the personalized fat loss journey by helping consumers understand how they respond to different exercise or diet changes in real time.”
