How am I suppose to loose 30lbs I'm 155 that will bring me to 125 and I think that's way to thin. I'm a size 9 in clothes I don't want to loose my curves but I do want to be healthy I'm trying to stop the rice and bread but it's so hard ! I wish there was a miracle pill lol and I love red bulls which I think has a lot to do with my weight gain
