First Week of healthy eating

I'm 5'8", 150lbs, wear a size six and I want to lose 20lbs or fit into a size 4 (which ever comes first). I'm a vegetarian but have a heavy addiction to bread and everything that has carbs. I workout but not on a regularly. On the night of 11/8/09, I decided that I WILL lose that weight. I decided that I will go to the gym at least 4X per week and at least one hour cardio in additon to other exercises. Today is day five and I've done ok so far. I still eat carbs but not as much as before, I've been to the gym 2X for the week (hectic schedule), I drink lots of water and green tea. Also, I log everything I eat and take my multi vitamins daily (I hate taking those things!!!). Have not jumped on the scale yet but plan on doing so at the end of week #2. Here's what I've been eating so far. Wish me luck... (I cook with pam canola spray- No heavy oils)
