The Circadian Diabetes Code

The Circadian Diabetes Code, a follow-up by Salk Institute researcher Dr. Satchin Panda, applies his circadian-rhythm research specifically to preventing and reversing prediabetes and type 2 diabetes, conditions the book notes now affect roughly one in ten Americans with diabetes and more than a third with prediabetes. Building on the time-restricted eating approach he popularized, Panda argues that shifting when people eat, sleep, and exercise — rather than relying solely on restrictive dieting or medication — can meaningfully improve blood glucose control and reduce the cardiovascular and weight-related risks that often accompany diabetes. The book walks readers through identifying their optimal eating window, structuring meals and exercise timing to blunt blood sugar spikes, prioritizing consistent and adequate sleep, and understanding how meal and medication timing interact, including how circadian strategies can enhance the effects of newer diabetes and weight-loss medications like GLP-1 agonists. It's written for readers who are prediabetic, diabetic, or at elevated risk, and who want a research-grounded lifestyle framework to use alongside medical care rather than as a replacement for it.
