The Impact of Various Exercise Intensities on Energy Expenditure Metabolism

The goal of this observational study is to learn about the effects of physical activity in adult on metabolic response. The main question it aims to answer is: * if physical activity is unlimited to increase the total energy expenditure (TEE)? Participants will engage in the following measurements: * Record their daily physical activity by GT3X. * Measure TEE by doubly-labeled water (DLW) method * Measure basal energy expenditure(BEE) and thermic effect of food(TEF) by respiratory chamber
