20 years old, 20 pounds to loose

Hi everyone :)
I'm new here. Call me Gee, I'm 20 years old and a half, I'm 174 cm for 73 kg.
My goals are 64 kg , a size 8 US in jeans, less boobs (I'm a D cup). I want a body that is fitter, abs, stronger arms and long lean legs !
I've been going to the gym since last October but my eating wasn't great. My new challenge is to keep up the hard work plus a better diet.
Please add me , we're a team !
