I need to loose weight fast

Unfortunately you can't drop a lot of weight that fast without it harming your body. Technically you're not even supposed to lose more than a couple pounds per month, and stay healthy. You shouldn't give a hoot about the other girls' bodies. Honestly, who cares? If you're really that uncomfortable with your body, perhaps you should consider not dressing down as much as everyone else? All I can say is for the next few weeks, eat really healthy, figure out an exercise routine, and drink lots of water!

Who cares what other girls bodies look like? Who said that a playboy model was the definition of beauty? You have to decide what you think is beautiful, and hopefully you will find to have nothing to do with weight. You can weigh 180lbs and still be attractive, both intellectually and physically. Once you've achieved a high opinion of yourself, then, if you feel you need to...(possibly to better your health)...lose weight slowly, and in a healthy fashion. I hope you take my advice! Good luck!
