One of the personal changes I was surprised by when adopting David Allen's work was how relatively efforlessly I lost 15 pounds [1]. In my case a simple engineering-based approach worked: Calories in < average calories burned. But keeping it off can be a challenge. What helped a lot was my wife's adopting the Weight Watcher's ("WW" from here on) program [2], which not only opened my eyes to how I thought about eating, but also kicked off some thinking about how WW and GTD are very much alike.
