It is hypothesized that our inability to confirm that energy substrate mobilization is a limiting factor for cold-induced thermogenesis (M) in humans (1, 2) is due to a sub-optimal dose of ingested substrates. This hypothesis was tested in healthy males exposed twice to the cold (3h at 7°C, 1 m.s−1 wind, nude, fasting) following the ingestion of either a placebo or a high-energy food supplement (710 kcal or 2,970 kJ). The supplement did not influence body temperatures, M or heat debt, even though it enhanced carbohydrate mobilization and oxidation (P |
