    The 13 C of breath reflects the 13 C of the fuels being oxidized, and because metabolic fuels differ in 13 C fractionation, breath analysis via CRDS indicates fuel switching in real time (41,60). During cold winter months, it is difficult for some animals to endure cold temperatures, and it is also difficult for them to find food.
