Yes your daughter is definitely obese
and her weight should have ideally been 55lbs.
Since all the medical reports have ruled out the common health issues related to obesity what i would like to know.... Is there a hereditary cause.i.e are the other family members also on the heavier side?
Here are few things you could try:
1)Involve the child in shopping,planning and preparing healthy meals and educate the child
regarding the benefits of healthy food.
2)Discourage eating snacks or meal while watching TV
3)Limit the time spend watching TV, video games and computer to 2-3 hrs.
4)Encourage physical activity like walks, bike rides, hikes, and active games
