yes, that sounds really good to me. I would make sure you are adding some strength training in there somewhere. People underestimate what some weights can do for your body. If you use low weights with a lot of reps you can stay lean and toned and not bulky, like most woman fear.
Cardio is such a great way to stay in shape and really works your whole body.
Also try and switch up your routine of running. Use different trails to go on, or do some interval running and incline(uphill) running. Your body easily adapts to excerise after weeks/months.
If you see your body isn't responding as well, change the workout up!
Self magazine has some good running workouts or just search it online.

how far do you run? well it would help with a balanced diet.. :-)

Actually yes the new reccomendations is to do some type of excercise for an hour everyday. But you must follow with a healthy, well balanced diet. If not, you are doing it for nothing.

if you watch what you eat yes its more than enough to lose weight. ive been jogging 25 min this week and ive already lost 5 lbs in 7 days but im also not eating past 6 and not pigging out at meals

I'd say so. Anything is better than nothing at all. 15 minutes would help.

Not if your body has become used to it.

yes! i've been jogging monday-friday for 15 minutes a day and i lost 6 lbs in the first 2 weeks and have consistently decreased and kept off the weight since then. it's better if you run on weekends, too. just to be consistent. and try to eat healthier! i know it sounds hard, but you get used to it and will stop craving oreos and cola and start craving apples and raspberry smoothies :

oh yeah thats what i do and my weight been the same for ever

Sorry, but no. All the jogging in the world won't help unless your diet is in order. Don't get me wrong -- jogging is good for you and it's a great fat-burner, but my co-worker runs five miles a day and he's still about 40 pounds overweight. So don't look at jogging as the Holy Grail of weight loss. It's just one tool in the toolbox. Eating a well-balanced diet and keeping the "bad for you" stuff to a minimum is even more important because your diet will make you or break you.
