The Momentum Plan

Weight Watchers's 2009 MOMENTUM Plan combines the best elements of the former Flex and Core. From Flex, the ability to eat any food, with portion control and tracking. From Core, eating foods that sustain you longer and listening to your body's signals.

Continuing with the 4-way approach of Eating Smarter, Moving More, Building Helpful Habits, and attending weekly meetings, you can lose weight by focusing on foods that are "filling foods."
