Skippy Peanut butter?

I was wonderin how bad is skippy pb. I want to drop a few pounds and ive eaten healthy todays lots of veggies and fruits and water. But right now I was kind of hungry and remembered that peanut butter makes u feel full. Sooo I had 1tbsp and was wondering if it ruined my day. I still need to excercise right now and also wanted to know if it would "burn" all the bad stuff from the peanut butter. Thanks
