Cut your fat grams down. 80 grams of fat per day is break even. If you take in 80 grams of fat, your weight will stay the same. If you take in 60, your body will still burn 80 and it will find those 20 grams from somewhere on your body. And you can keep extending that... if you take in 40 grams, you burn 40 stored, etc..... No matter what the math, 80 grams is what you burn to stay even. I would suggest you cut your fat grams back as far as you can and add crunches and aerobics (step is great). It may take 6 weeks to see the results you want, and you really can't rush it. You don't have a lot of body weight to start with, and a pound a week is about right. In my case I was 75 pounds too heavy so that first 20 came off quickly.

I would also like to address one thing. I see a lot of people say that walking is a great exercise, and they are right. WALKING is. STROLLING is not. You need to push yourself hard if you walk and call it exercise, to where you cover a mile in 15 minutes or less. That is just 4mph, not hard to do. Soldiers force march about 6mph, which is a mile in 10 minutes.
