How to Reset Your Master Clock to Prevent Cancer & Alzheimer's

Dhru Purohit and Dr Satchin Panda take on the master clock, the pacemaker in the brain that sets the tempo for every other clock in the body, and what happens when daily life pulls it out of alignment. The framing is preventive rather than therapeutic. Losing rhythm is treated as a quiet, cumulative trigger for chronic disease, cognitive decline and immune dysfunction, not as a problem that begins the day a diagnosis arrives.

The ground underneath the conversation is three decades of work at the Salk Institute. Dr Panda's laboratory established that the clock in the liver follows when an animal eats rather than when its eyes see light, which made meal timing a lever anyone can pull. His group has since mapped daily rhythms of gene expression across more than sixty tissues and brain regions, and shown that healthy rhythms lower risk across inflammation, cardiovascular disease, cancer and dementia, while those same diseases in turn flatten the rhythms.

The discussion also reaches his newer work on measuring and reversing biological age through rhythmic optimisation, including research tied to the XPRIZE Healthspan competition. A good entry point if you want the disease prevention case for circadian health rather than the weight loss one.
