Once, when I was nine years old, my older sister—then 15—invited me to her room. This in itself was an honor and a privilege, but today there was something even better: Kira was about to embark on a disciplined but rewarding diet of fat-free foods, and she wanted to know if I would join her. We would be partners! We would support each other, encourage each other, lose weight together! There would be challenges, of course, but together, we would succeed.
The first step, Kira explained, was to eliminate existing temptations, such as the great stock of Halloween candy currently occupying a corner of my bedroom closet. It wouldn’t do to try to ignore it, or to save a small selection for later, or even to enjoy one final fun-size Milky Way. The candy must go.
