Abstract
In this study, in order to clarify the effect of breakfast-style dietary intake on thermogenesis and thermoregulatory responses in young females, twelve healthy females (19-20 years old) took a meal of 450 kcal or did not eat any food and were subsequently kept at rest for 2 hours under air conditions of 25ºC and 40%RH. The meal produced diet-induced thermogenesis (DIT) of approximately 13% of resting metabolic rate for two hours. The DIT led to an increase in skin temperature on multiple body sites, which may be attributed to enhanced cutaneous vasodilation, but did not affect sublingual temperature as an index of core temperature. Regional differences exist in the increase in skin temperatures and it became remarkable on the upper body as a whole.
