Wendy---I think that even if you're going through a period of not losing much (the old, infamous "plateau" stage) you can ONLY do yourself lots of GOOD by continuing your exercise. That's one area where I'm weak. I used to hike a lot, but haven't done it in months.... I think exercise makes your body look really good, beyond what a diet can do, and of course, it's SO good for your heart, etc.
