Kinetics of oxidation of total and exogenous metabolic substrates after gavage of a labelled liquid mixed meal, in mice fed a HFD for nine weeks (second mouse study). (a) Instantaneous total (n = 47) and exogenous (n = 23) glucose oxidation after administration of the 13C glucose liquid mixed meal until the end of the measurements. (b) Data from panel (a), emphasizing the early 2 h postprandial period. (c) Instantaneous total fat oxidation (n = 47) and exogenous palmitate oxidation (n = 24) after administration of the 13C palmitate liquid mixed meal. (d) Data from panel (c), emphasizing the early 2 h postprandial period. (e) Cumulative exogenous glucose (n = 23) and palmitate oxidation (n = 24) after administration of the labelled liquid mixed meals until the end of the measurements. (f) Data from panel (e), emphasizing the early 2 h postprandial period. Exogenous substrate oxidation data is calculated from conventional InCa data (VCO2) and 13CO2 and 12CO2 data. Shaded areas represent the dark phase. Data is presented as mean ± SD. InCa, indirect calorimetry; PW, postnatal week.
