Correlation analysis between cumulative exogenous glucose or fat oxidation after gavage of a labelled liquid mixed meal and body fat mass and ∆RER, in mice fed a HFD for nine weeks (second mouse study). Exogenous glucose oxidation from 0–2 h (a) or 2–13 h postprandial (b) expressed per unit of LM is not significantly correlated to FM. Exogenous palmitic acid oxidation from 0–2 h postprandial expressed per unit of LM is not significantly correlated to FM (c), but it is negatively correlated to FM 2–13 h after ingestion of the liquid mixed meal (d). Exogenous palmitic acid oxidation expressed as a percentage of total fat oxidation correlates negatively with FM, both from 0–2 h postprandial (e) and from 2–13 h after ingestion of the liquid mixed meal (f). Exogenous palmitic acid oxidation relative to total fat oxidation correlates positively with ∆RER, both from 0–2 h postprandial (g) and from 2–13 h after ingestion of the liquid mixed meal (h). n = 24.
