In terms of calories burned and eating enough, I think it helps to think about this as a weekly average, rather than what happens on any specific day. The body should have enough reserves to cope with a 5 mile walk.
Also, rapid weight loss is typically only experienced with those with a lot to lose, and weight loss typically slows down as you approach your goal weight. With just 13 lbs remaining to lose, 0.25 - 05 doesn't sound unreasonable.
In terms of adding more exercise, you are probably better off adding strength training to the mix, rather than more walking.
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
