The Nutrion device is a handheld breath analyzer developed by researchers to measure when the body is burning fat by detecting acetone in exhaled breath. Presented in a study published in the journal Device, the system monitors ketosis by analyzing a metabolic byproduct associated with fat being used for energy. The portable device incorporates moisture and contaminant filtering alongside a companion app that guides users through the breathing process to improve measurement accuracy outside laboratory settings.
In testing involving 12 participants across different diet and exercise conditions, the device produced results that closely matched traditional laboratory methods for measuring ketosis. The companion app also monitors breathing pressure and sampling timing to help generate consistent readings comparable to blood-based ketone tests. Designed for metabolic monitoring, the technology could support applications ranging from evaluating nutrition strategies and athletic performance to assessing the effectiveness of GLP-1 therapies through non-invasive breath analysis.
