Assigning blame

How is that one can travel through Italy, eat delicious three-course meals, with wine, and lose weight, yet in San Francisco, I sit in front of a computer all day, eat half as well, and slowly put on the pounds, despite daily, and I mean daily, trips to the gym (yes, I exercise when I get there). I'm exploring how I can keep earning an income (which requires me to sit in front of a computer all day), keep my weight down, and still enjoy the foods I eat along the way. Stay tuned!
