Sunlight or fake light? We explore how light timing and intensity shape the circadian clock, mood, hormones, fertility, and sleep—and why amplitude is the missing key. Sean Kane shares new research on individual light sensitivity, depression and bipolar patterns, and practical fixes that work.

Sean Cain, PhD is a Matthew Flinders professor of circadian biology at Flinders University, Australia. He has more than 25 year of research into human circadian system and how light affects health.

We dig into why visceral fat drives disease risk, how to spot it on sight and imaging, and the levers that shrink it without losing muscle. We map a practical plan across food, fasting, light, stress, and training, and weigh GLP-1s and surgery against lifestyle-first care.

Christopher J. Stadtherr, MD is a board-certified physician in Family Medicine and Obesity Medicine, with expertise in nutrition and metabolic health.

He practices metabolic medicine in a direct primary care (DPC) model out of Gig Harbour, WA, USA and is committed to helping his patients reverse their diabetes, improve their metabolic health, and avoid the myriad complications that necessitate hospitalization.
