Total energy expenditure (TEE), sleeping metabolic rate (SMR), thermic effect of food (TEF), and spontaneous physical activity (SPA) were measured at thermoneutrality (22°C) in response to 50% overfeeding at baseline (open bars) and following four weeks of cold acclimation (closed bars). Cold acclimation did not induce changes in energy expenditure at thermoneutrality, as measured by respiratory chamber (p ≥ 0.15).
