Welcome Kelly,
I am new to this site as well. Like you I am not following a weight loss plan. I have made changes with the types of food I eat and portion size. Exercise has been key to my weight loss. It was a slow start, but I exercise 6 days per week now and actually look forward to it. I walk during my lunch hour, and in the evenings I work out using a collection of Leslie Sansone, Walk Away the Pounds, DVDs. I also do yoga/pilates twice a week and some strength training. This has worked for me and I am noticing a lot of changes in both the way I look and feel. You just have to find something that works for you, and your lifestyle, and stick to it.
Good luck.
