Re: So when does the weight come off?
Diet, Diet, Diet. Walking is a great start but it's not The Solution to weight loss. If you don't clean up your diet, you can walk all day and not lose weight. But, for the record, one week is hardly enough to see a significant change. It's possible that the extra exercise is increasing muscle a little bit and helping you lose a little bit of fat, but the scale will not show you that kind of progress. If you're able to start at 4 miles, by all means, go for it, although increasing the *intensity* for a shorter duration if you can will help too, so you're not spending all day walking.
