Hi, I read the book two days ago, cleaned out my pantry, freezer, and fridge and then stocked up on low carb foods.  I followed the less than 20 carbs a day faithfully for two days now and couldn't resist getting on the scale.  To my dismay, I gained two pounds!  Is this common?  I am vegetarian but it doesn't seem like that would be a problem.  Any ideas on why this happened?  Thanks...also, this is my first time to post to anything and I didn't really want to 'poll' anyone but maybe that's what a post is called??
