Will it hinder weight lose if 2oz peanut butter is used twice daily with fruit or veg?

I am on a new eating program where I eat 6 times a day. Sometimes I just grab and go with 2 oz of peanut butter and either 1/2 veg or fruit for my mid morning and mid afternoon snack. I was hoping this would not hinder the weight loss. I have lost 25 lbs in 2 months so far.
