I know this post is a tad old, but wanted to comment.
I use the MyFitnessPal app (you can also use it on PC) to record foods. I upped my produce intake greatly and cut meat intake to one meal once or twice a week. I don't eat any grains that are not whole grains. I eat six small meals a day rather than 3 larger ones.
As far as exercise, I own 3 of the Leslie Sansone Walk at Home DVDs. They are so great and relatively low impact.
