The Circadian Code

Dr. Satchin Panda is a professor at the Salk Institute and one of the world's leading researchers in circadian biology. In *The Circadian Code*, Dr. Panda presents research showing that managing your biological clock is the single most powerful lever for reversing metabolic syndromes, losing weight, and optimizing immune system response.

SCN vs Peripheral Clocks

While the Suprachiasmatic Nucleus (SCN) in the brain is the "master clock" synchronized by light, Dr. Panda discovered that every major organ—the liver, gut, kidneys, and heart—contains its own peripheral clock.

When light exposure and eating times are misaligned (e.g. eating late at night while sitting under bright lights), your peripheral organs fall out of sync with your brain, triggering metabolic strain, inflammation, and insulin resistance.

Time-Restricted Feeding (TRF)

Dr. Panda's research pioneered Time-Restricted Feeding. He advocates for keeping all calorie consumption within a strict 8-to-10 hour window (maximum 12 hours).

> A critical rule: your circadian clock begins ticking the moment you consume anything other than water (including black coffee or tea, which trigger liver enzymes).

How ARC Applies This

ARC integrates Dr. Panda's findings directly into daily routines. By coordinating your sleep timeline, ARC schedules a custom Feeding Window tracker, sending alerts when your digestive fire is entering its peak phase (usually around noon) and reminding you to start a "digestive sunset" to begin your 14-hour fast, protecting your liver and sleep.
