This study examined the effect of energy restriction in lunch on lipid metabolism and task performance when the activities simulated the daily life at physical activity level n are performed under 3 conditions; Intake (intake lunch of the normal calories), Half (intake lunch of the half calories), and Skip (skip lunch). In results, it was revealed that energy control of lunch increases fat oxidation rate in inverse ratio to amount of lunch without lowering task performance. Appetite sensations also change according to amount of lunch and feeling of hunger stayed at significantly lower level compared to Skip for about 3 and half hours after energy controlled lunch. These results indicate the possibility that energy control of lunch reduces body fat during daily activities and improves deteriorated heat tolerance.
