Outline of Final Research Achievements

This study aimed to clarify the effect of light exposure on diet-induced thermogenesis (DIT) without relying on food intake. DIT is one kind of energy expenditure. Another aim of this study is to clarify whether the effect varies with human physical features (body-mass index: BMI). In the results, we found that light exposure significantly affected energy expenditure independent of food intake. The retention of ordinary light-dark cycles may be recommended for keeping biological rhythms, making up for physical features, and health maintenance.
