It's not unusual to lose a lot of weight the first few weeks that you start to train. Sorry to tell you this, but the majority of the weight you lost was water. If you continue to train and watch your
diet, normal levels of
weight loss should be about 2-3 lbs a week.
As far as walking more, I don't suggest it. The
body will ALWAYS adapt to whatever
stress is imposed upon it. So, if you walk 6 miles the
body will adapt to it and you will have to do 7, 8, and then 9 miles.
It's a little rediculous I know, but the
body has a defensive barrier to protect itself. Therefore, train, do your
cardio and be patient.
Hope this helps....
