Love this magazine - great, easy recipes, accurate nutrition and fitness news/information (several faculty members from the University of Vermont are on the advisory board). Did I mention that the recipes are delicious and healthy? :-)
I usually eat breakfast and lunch at my desk, which makes portion control a bit challenging. I invested in one of the Fit'n'Fresh kits from the Spark Store and keep a small portable scale from the set in my desk drawer, along with an inexpensive set of dry and wet measuring cups.
Finding mentors for healthy eating and exercise was key for me. Modeling some of my behavior on the positive examples of healthy friends and removing many of the negative influences has changed my life.
