15 pounds!
Nice job.
The elliptical trainer is the way to go.
My diet plans are about the same. Smaller portions and probably a little more protein. I never have been much of a soda drinker or fast food junkie so no issue there. As for alcohol, no way I will give it up, but I've been trying not to drink much during the week.
The excercise is the most important and needed change.
