Bet you never knew that a pen could be your best weight loss tool.

It's true. In one of the largest and longest weight loss maintenance trials ever conducted, the more food records that dieters kept, the more weight they lost.

Scribble for Success
Simply jotting down what you eat seems like an easy price to pay for fewer pounds. The people in the study also followed the DASH diet, attended weekly group sessions, and exercised for at least 30 minutes a day. After 6 months, the people who had also kept daily food records lost twice as much weight as those who did not keep track -- probably because the food journals encouraged people to reflect on what -- and how much -- they'd eaten.
