I'm a 23 year-old research scientist (hopefully starting medical school in August) in Memphis, Tennessee. I'm originally from Fairbanks, Alaska and lived there until I was 11. I didn't really have a weight problem until I moved down here, and now I'd like to fix it. It affects my self-confidnce, it prevents me from doing things I would really enjoy, and I'm really not wanting to develop any serious conditions, such as diabetes or hypertension. I don't really care how long it takes (though 12 months would be nice), but I'd like to lose 100 pounds.
