Good morning SplitImage, you say you really aren't into exercising? Well, the secret is to not "do exercising", but find something where you simply move more than sitting or being in bed. Then increase the movements as you go.
Walking is something most of us do everyday anyway and is so good for helping with the weight loss. Just add some little 'activity' to what you do now. If it is sitting at the computer for hours with job hunts, make yourself get up and walk a round about your house every 30 minutes or so. Park away from the grocery store doors, take the stairs, etc. It may not seem like a lot, but for those of us who don't enjoy 'exercise', that is a good way to increase daily movement.
Good luck with your apointment with your "diet guide".
