A new handheld breath test device can accurately measure when the body is burning fat in real time by detecting acetone levels in the breath, a compound released during fat metabolism. This innovation could help individuals manage weight loss more effectively without waiting for visible changes on the scale. The device, developed by researchers at the Swiss Federal Institute of Technology in Zurich, uses a smartphone app to guide users’ exhalations, enhancing accuracy by separating acetone from other breath components. In a small trial with 12 participants, the device’s readings closely matched those from a highly accurate laboratory technique, suggesting its potential reliability. However, further testing is needed to confirm its accuracy across a broader population. The device, called Nutrion, has been commercialized by Alivion AG, a spin-off company from ETH Zurich.
