Here are some links to some guides, resources and other fun things we use at Fitting It In:
TheSpotter.Net: Chris's web site, full of good tips and tricks.
FitDay.com: track what you are eating, and by doing so, track where your calories are going, whether you're eating too much or too little, whether you eat too many carbs or too much chicken, or too many Oreos. This journal is a vital part of Melissa's program.
