I use the Runkeeper app on my Iphone. Not only does it track my run but it also plays the songs that are on my phone.

Try carrot or celery sticks, or a bowl of steamed cauliflower and broccoli. http://homecooking.about.com/library/archive/bllowcalsnacks.htm has other low calorie snacks.

I would not add any weights. Adding weights could result in an injury, due to changing your posture while walking. I would try to increase the pace of your walk or do short intervals of jogging in-between walking.

Have found that weight fluctuates too much from day to day, so only weigh myself once per week.
