Weight loss help! i need to loose the pudge?

I am a 5'7/5"8 female, 20 years old, very curvy body shape. In December i weighed 183- as of today I weigh 158! I am very proud of myself, and I did it mostly but minor exercise and changing my diet to extremely healthy. I look great. THere is just that little pudge of fat on my stomach. WHen I stand up you cant see it its just that little extra pudge/skin that hangs over my jeans when I sit down. HOW DO I GET RID OF THAT? also I have a BIG booty and I just want to define it a little and lift it, NOT loose it!!! (I am 36, 28, 41)
