Takahashi Lab
Machine-translated · View original
A lab that studies how diet and exercise relate to the circadian clock in humans.
AboutAbout the lab
Exploring the interaction of the circadian clock with nutrition and exercise
The Takahashi Lab studies the interaction between nutrition and eating habits and the circadian clock (chrono-nutrition).
It also studies the interaction between exercise and physical activity and the circadian clock (chrono-exercise).
Centered on experimental and epidemiological studies in humans, the lab conducts research in collaboration with researchers in Japan and abroad.
Its work includes building a clinical foundation for chrono-nutrition, eating habits with a focus on the menstrual cycle and low body weight, and exercise and physical activity based on the circadian clock.
Key terms

*Illustrative imageTiming of Meals and Exercise in Older Adults
The effects on the body change depending on when you eat and when you exercise. In older adults, the lab examines the timing of eating main and side dishes, morning versus afternoon exercise, and the effects of warm protein drinks, seeking lifestyle approaches to prevent age-related decline.
*Illustrative imageThe Circadian Clock in Pregnancy and Infancy
A mother's meal timing and exposure to light at night affect the circadian clock during pregnancy and the baby's development. The lab is developing a questionnaire to measure the meal rhythms of pregnant women and studying how mothers' lifestyles relate to their babies' sleep rhythms and growth.
*Illustrative imageMeal Timing and Mental Health
Irregular meal timing may lead to low mood. The lab studies the relationship between meal rhythms and mental health in children, young people, and groups such as airline cabin crew who work across time zones.
