Bodily fluid analysis system capable of assessing effect of gut health on weight loss or other health program

Abstract

A breath analysis system includes a breath analysis device that measures acetone, and a gut biomarker such as methane and/or hydrogen, in breath of a participant in a weight loss or other health program. The system includes one or more processors that use the measurements to assess the progress of the participant. For example, the system may use the gut biomarker measurements to assess whether the measured acetone level accurately represents fat metabolism. As another example, the system may determine, based on changes in acetone and gut biomarker levels, whether a diet change is producing a gut health issue that adversely affects the body's ability to metabolize fat. The system may also generate diet/nutritional recommendations. Embodiments are also disclosed in which some or all of the analyzed analytes are measured in the participant's blood rather than in breath.
