Opinion | In a World of Addictive Foods, We Need GLP-1s

Interesting to read. The prev. FDA commissioner & dean of Yale med. now a GLP-1 enthusiast.

QT:{{”
Throughout my life I’ve been fat, thin and various sizes in between. Since I was a kid, I’ve gained and lost weight repeatedly, putting on 20 pounds, taking it off, putting on 30 pounds and then losing it again. It has been a cycle of despair.

The fact that I’m a doctor, was a dean of two medical schools and ran the Food and Drug Administration for six and a half years was of no help to me. Like millions of others, I was caught between what the food industry has done to make the American diet unhealthy and addictive and what my metabolism could accommodate.

We may now be at the brink of reclaiming our health. New and highly effective anti-obesity medications known as GLP-1s have revolutionized our understanding of weight loss and of obesity itself. These drugs alone are not a panacea for the obesity crisis that has engulfed the nation, and we should not mistake them for one. But their
effectiveness underscores the fact that being overweight or obese was never the result of a lack of willpower.

Frontiers of Quantum Complexity and Cryptography Lecture 2 – Mixed States and Density Matrices
Lecturer: Henry Yuen Spring 2022
Scribes: Melody Hsu

In the third lecture, we wrapped up a review of the foundational concepts we will need to tackle
later topics, and then started our first quantum complexity topic, state tomography. We briefly
discussed several ways to analyze probabilistic mixtures of quantum states; after the conclusion of
the review, we explored lower bounds on complexity of a classic tomography protocol.
