Online Weight Loss/ Weight Management Programs for Kids

If her parents have health insurance, a nutritionist is a great place to start.
The nutritionist can talk to her about her food cravings, and show her what
a proper diet looks like. The whole family needs to get on board for this lifestyle change, though. If it's just the girl having to "diet" she will resent it and rebel against it. Likely if she's singled out for it she will just gain more.
If the whole family does it- she will more likely go along with it because she
isn't being singled out.

Another good thing to do for the girl and her whole family is to measure food.
I was shocked when I started measuring my food. My portions were too big.
Eat on a smaller plate. And, if she gets hungry while she's adjusting her body to the new portions- she should drink a glass of water and eat a carrot, some celery, or an apple. Those won't hurt her overall "diet"-
Oh- and cut out as much refined, processed foods as possible. If it comes in a box, a bag, a can, or pouch - you probably shouldn't eat it.

And encourage her to play for at least 60 minutes a day.

I agree that the first stop needs to be at the pediatrician's office. She needs complete physical and bloodwork. If that checks out ok then the whole family needs a reality check about diet and nutrition. A visit with a pediatric nutritionist would be a great place if they can afford it. But there is lots to learn on line.

Whoever is doing the cooking and grocery shopping needs serious education to make good food choices.

They also need to tread carefully given this child's age. It all has to be done in a positive light. If she is already sneaking food there is something going on physiologically with her relationship with food. She needs to learn how to have a positive relationship with food now. Food is one thing none of us can get away from and she needs to learn how to deal with food. In my house there are no foods that are entirely off limits but it's all about everyday foods (wheat bread, veggies, fruits,lean proteins) and sometimes foods(ice cream or cookies, etc).

If a ten year old outweighs an adult by 60 lbs, yes she needs help. Not just an online weight program. She needs to see a doctor. With her being active, this kid would literally have to be eating 24/7 to be at a weight like that. She needs blood work done to make sure nothings wrong. Is she on steroids for allergies?? Yes, tell your friend she needs to stop giving in, get rid of junk food and take her daughter to a doctor and counselor.

I will say the thing NOT to do is have the mom hound her for her weight. My parents did that to me and I was only chubby, but every time I would take a bite out of something, "a moment on the lips life time on the hips" or something like that. It really made me self conscious and have low self esteem and then I ate even more. Many times over eating is due to either lonliness or boredom. This girls parents can help her by eliminating all sweets and junk from the house and replacing them with healthy alternatives and by serving as an example to healthy eating. A lot of local gyms have programs for kids. If she can't find something, she should hire a trainer that can work with both mom and kid (even if mom is of normal weight) and see a nutritionist. But I would also look at the mental health aspect and try to figure out why she is never full and address those issues.

I know of a great online weight management program - www.vfl.com, but it is not strictly geared towards kids. Good luck!
