This is a great idea for a post. Unfortunately my first pound was so long ago I can't remember! Really, two years seems like a loooong time to only have lost 45 pounds, but my body is stubborn. I *think* I lost a couple pounds my first week, which was encouraging enough to keep me going even though my weight loss is rarely more than 4-5 pounds a month these days.
Just stick with it and that first pound will be off in no time.
