Hello! I'm Katie and I'm 17. For the past three years or so I have been trying to lose weight. I'd lose about 20 pounds over summer break, but gain it all back (and then some) when school started again. I've decided to join this board for accountability and motivation (I'm also looking forward to the challenge threads!). This is my last semester of high school (woohoo!), and I have some big events coming up in April and May.. prom, the senior trip, graduation, etc.. I want get down to a healthy weight for those events and college. I'll be starting a new time in my life, and I want to be in the best shape as possible!
