Dr. Satchidananda (Satchin) Panda is a professor in the Regulatory Biology Laboratory at the Salk Institute for Biological Studies.

In this video we discuss...

• (00:00) Introduction
• (06:42) Why humans developed an internal clock (i.e., the circadian rhythm)
• (15:28) Light is necessary to regulate our circadian clock
• (25:02) Morning bright light exposure lowers cortisol levels and lifts mood, but the indoors are dim
• (30:25) Using light exposure to reset jet-lag and help shift workers stay healthy
• (36:17) Eating is an important regulator of the body's peripheral circadian clocks
• (40:44) Time-restricted feeding protects from the harmful effects of a Western diet
• (48:30) Time-restricted feeding increases muscle mass while reducing fat mass
• (51:03) Mice who fasted 15-16 hours-per-day gained muscle endurance due to changes in mitochondria
• (54:43) What's the difference between intermittent fasting and time-restricted feeding?
• (01:00:02) Melatonin makes us less insulin-sensitive in the evening 
• (01:05:56) Dr. Panda's time-restricted eating mobile app helps research participants track their food
• (01:20:39) Time-restricted feeding improves heart health 
• (01:27:31) The gut microbiota also follow a circadian rhythm
• (01:34:12) How to participate in Dr. Panda's research
