That is no surprise that these many kids in the USA think they are okay and it is partly due to the fact many parents are obese and overweight so they think if they are overweight why can't I be? Which is fair logic actually but the other aspect isn't fair and will be brutal to them for their whole life and that is this whole body acceptance thing. Sure you should accept your body but not if it is going to put you in an early grave..this should be stopped before many people head to their grave 10-20 years too early.
