I always thought weight loss was hard because I’d witnessed people throw themselves at it hardcore and then fail just as hard. In contrast, I chose an easy, long-term, data-driven plan and stuck with it. Small changes over a long time make a big difference.

Chad Austin used The Hacker's Diet, which says if you eat 500 calories a day less than you burn, you'll lose one pound a week. Aggregate that over a few months and it seems like doing this diet is a real no-brainer.
