I realize that I can't out-exercise a poor diet.  In order for me to lose weight, I have to also exercise.  I feel like walking is the best exercise for me, for now.  However, I think that there are other exercises out there that I can do.  For instance, I am interested in dancing and certain low impact walking exercises from DVDs on Youtube.  Zumba seems like fun.  I have tried that before, yet it is quite hard.  I have had to struggle to "connect the dots" between diet and exercise.  All I have to do is to start off slow.
