Once again...I know I'm not a teenager, but I'm 5ft3, & weigh 138lbs. I know I'm not overweight, but I would also like to get to a healthier weight, say 120-125lbs. Not to crush your weight loss goal, but I think you probably look fine the way you are! 105 is WAY too skinny....in my opinion. (Even for someone younger than 24)! :-)
