No one is the same so your metabolism rate shouldn't mean jack shit in terms of losing weight, it might take a week and a half instead of a week. I have the tendency to yo-yo between a 20 lb range so it isn't that hard to lose weight as a girl (being tall that is little pudge vs no pudge for me). But really though?? If you want to lose the weight, you have to adapt to your body. Which should never need to be done unless you live your life through others or neglect your body to the extent you don't know how it should work.
