Dr. Satchin Panda on How Your Body Clock Shapes Metabolic Health

Meal timing, morning light, sleep, and exercise can all influence circadian rhythm, with potentially important effects on metabolic health.
In this episode, Dr. Bret Scher speaks with circadian biology expert Dr. Satchin Panda about how our internal clocks work, what disrupts them, and how everyday timing choices can affect metabolism, brain function, and long-term health.
Dr. Panda describes how light helps synchronize the brain’s central clock, while food timing may influence clocks in other organs and tissues. He also breaks down why the timing of your first and last meals matters, what shift work can do to metabolic health, and how even a one-hour clock change for “daylight savings” can disrupt circadian biology.
They discuss:
• How circadian rhythms influence metabolism and brain function
• Why morning light and daytime light exposure matter
• The difference between central and peripheral circadian clocks
• Why Dr. Panda recommends waiting one to two hours after waking before eating
• Why eating several hours before bed may support sleep and metabolic health
• Why the timing of a time-restricted eating window matters, not just its length
• What research in firefighters suggests about food timing during shift work
• Practical strategies for people working overnight or irregular schedules
• How light exposure is being used in some mental health settings
• Why Dr. Panda favors permanent standard time over changing the clocks twice a year

Dr. Panda’s research offers a practical framework for thinking about circadian health. Paying closer attention to habits like when you eat, get sunlight, exercise, and sleep may help keep your internal clocks better aligned.
