Your Most Stylish Year Ever

Nutritionist Jackie Keller, who has created meal plans for Angelina Jolie, Charlize Theron and Uma Thurman, says to plan ahead with snack packs. She combines salt-free roasted soy nuts with dried edamame, cranberries and dark-chocolate chips for an easy, high-protein trail mix. Also, when seratonin levels dip at 4 P.M., don't grab chocolate; have a small baked potato instead, which can be made in your office microwave in just a few minutes.
