Abstract Expired breath $δ^{13}CO_{2}$ measured in real time serves as a useful biomarker of altered macronutrient metabolism in response to changes in energy balance. Altered breath $δ^{13}CO_{2}$ is believed to be a result of changes in macronutrient oxidation and the kinetic isotope effect where enzymatic processes discriminate against metabolites naturally enriched with $^{13}C.$ Use of breath $δ^{13}CO_{2}$ as a rapid biofeedback of energy balance status will enhance an individual's ability to modify behavior during weight loss efforts. Herein we describe a novel approach for immediate biofeedback for energy deficit using a moderate exercise challenge. Our new mid-infrared isotope ratio-meter for $δ^{13}CO_{2}$ is a step toward miniaturization of a personal device for instant biofeedback for people attempting to lose weight.
