| Research Abstract |
To investigate the effects on sleep architecture and energy metabolism during sleep, we made the differences between high carbohydrate and high fat meal for dinner. In each session, subjects consumed high carbohydrate (HCD: PFC =10:10:80) or high fat (HFD: PFC = 10:78:12) meal at 2000h. Slow wave sleep was decreased during the first sleep cycle although sleep architecture overnight did not change. Present study suggested the possibility that substrate availability during sleep affects substrate oxidation during sleep, and affects sleep architecture during the first sleep cycle.
We applied our original method that calculated thermic effect of food, considering the prolonged increase in energy expenditure after physical activity. As a results, our original method was rated the best based on two criterions: which returns positive estimates in all the measurements, and returns estimates close to gold standard method, in addition that ability to evaluation of time course of TEF.
