Does diet-induced thermogenesis change the preferred ambient temperature of humans?

Summary The thermal scores of nude resting subjects were followed for a period of 5 h. The subjects were sitting at rest from 0700 until 1200 hours at their previously determined preferred ambient temperature. Whether fasting or with a large (3.700 kJ) meal their comfort score remained the same and constant throughout the experiment. Their comfort sensation was not influenced by a significant, 20%, increase in metabolic rate produced by the meal, nor by the gradual rise in body temperature due to the diurnal rhythm.
