The Circadian Code

Three of the ideas you’ll keep

The Clif summary of The Circadian Code pulls out 7 insights. Here are the first three.

1. Every organ, from your liver to your gut, contains its own **circadian clock**, all synchronized by a **master clock** in the brain's suprachiasmatic nucleus (SCN), so health depends not just on what you do but precisely when you do it.
2. **Time-Restricted Eating (TRE)**, confining all food and calorie-containing drinks to a consistent 8-to-12-hour daily window, can improve weight, blood sugar, and sleep even without changing what or how much you eat.
3. Panda's Salk mouse experiments showed that mice eating a high-fat diet only within an 8-hour window stayed lean and healthy, while genetically identical mice eating the **same calories** around the clock became obese and diabetic.

The other 4 — and the full 11-minute summary — are in the app.
