The anti-fad diet
Two thirds of the weight comes back within a year of stopping Ozempic. I keep thinking about that number. And I keep coming back to a diet book published in 1991 that understood exactly why. The book is called The Hacker’s Diet. It was written by John Walker - co-founder of Autodesk and the original programmer behind AutoCAD. By his late thirties Walker had tried everything. Nothing worked. So he did what engineers do: he stripped the problem back to first principles, built a measurement system and ran the experiment on himself.
