listen girls im from Australia im 15 years old and i weigh 89kgs which is around/over 170 pounds and im about 5'10 i still have my baby fat or as some people say "a muffin top" i also have stretch marks from growing to fast because of over eating, im athletic i play 3 different sports 4 including PE or as you Americans(im not trying to be rascist or discriminative) call it GYM and i still cant lose weight but to be honest i dont care anymore because im still growing a doctor told me last year that i will grow to approx 6'2 which is really tall for a girl, but that means that my body will change more.....my point is dont worry about the outside worry about the inside... if your as healthy as a horse at 180-190 pounds then dont worry about weight loss because that means your body is happy as it is and can survive.
