Serum free fatty acids (FFA; a) and plasma glycerol (b) concentrations during the protocol from the time of ingestion. Serum FFA at rest only; measured at -30 min and 30 min (c). Inset c represents the change in resting FFA concentration. Plasma Glycerol at rest only; measured at -30 min and 30 min (d). Inset d represents the change in resting glycerol concentration. * Significantly different (P < 0.05) from the same value at rest or than the other condition (inset). ↓ Ingestion of capsinoids/placebo at 0 min. Values are means ± SD (n = 12).
