Is walking good exercise? plus how do you loose weight without excercise?

It's probably of your diet or you haven't been walking long enough yet. Eat around 1200-1500 calories a day, cut out all junk food, and eat small little meals throughout the day to keep your metabolism going. Keep on walking at least 5 miles a day and you should lose a lot of weight soon. My dad lost around 13 lbs in 2 months just from walking and watching his diet, because he's diabetic. Now, he's on his way to looking slimmer and he's lost a few pounds since then.
