How to lose weight walking

I have written several times about the many health benefits of High Intensity Interval Training or HIIT. http://notjustforboomers.blogspot.com/2013/04/high-intensity-interval-training.html For the most  part those have dealt with the use of a stationary bicycle and how you can increase your oxygen efficiency and decrease  your blood sugar and blood pressure by alternating periods of intense cycling with periods of rest or at a much slower pace.  What we have decided to do is to see if those same principles apply to interval walking. In addition several studies have shown that following a program of interval walking can result in significant weight loss over time.

We started a program today at our local high school track. We began walking at a fast pace for 440 yards followed by another 440 yards at a relaxed pace.  Most tracks are probably set up with lines on the track so it is fairly easy to measure the distance. The fast pace is about twice the usual walking speed.  We started with a mile and will build up to several miles in the next few weeks.
I have seen recommendations that this program be alternated with days of walking at a normal pace for 30 minutes. Some articles suggest that following this program can result in a weight loss of about a pound a week. We'll let you know if we find any success in this approach.
