I don't have the valuable personal insight many of these gals do, my teeth were bigger than the rest of my body when I was 13, and my whole family was very active together BUT I do have some valuable insight when it comes to being the example setter for an overweight child. My friend was a single father in the military, and got into a horiffic accident in January 2007 (people in VA might remember the army humvee rollover on 95N that injured three soldiers. He was the one that sustained a traumatic head injury and lost half his hand and had to be pried from the wreck by the jaws of life.)
He had a six year old little girl who I ended up being one of the primary caretakers for while he was in the hospital and recovering over the next year and a half. She was very overweight already, barely 4 and a half feet tall and already creeping over 100lbs. I was concerned. She wanted to eat nothing but fast food and junk, sit and veg out in front of the TV almost every waking hour, got tired walking a quarter mile to the park, didn't know how to ride a bike, etc. I don't eat that sort of stuff, and I definitely have never spent an entire day indoors in my life. It took her all of a whopping three days to adjust to the dietary change. The first time I fed her fresh fruit and salad she wouldn't touch it and whined and cried. Second day she finally took a few bites because I forced her and she was hungry. After the third day that's all she wanted anytime after that. If it wasn't fresh, she didn't think it tasted good anymore. She didn't complain when I treated her to a cookie or some other treat and broke it in half so we could share. It was pretty clear that *she* wasn't the problem, it was the adults around her setting a bad example and not imposing limits on portion size and WHAT they allowed her to eat and do. She got down to a still moderately overweight, but notably more svelte 68lbs while I was in charge of her. Not by forcing her to do anything she didn't want to, or withholding anything, but just by giving her healthier options (for example, if she really wanted a snack I would tell her what choices she had instead of letting her choose. She's 7, of course she's going to want a cookie if she knows we have some, but if I tell her she can have an apple or a few dried figs, a cookie won't even enter her mind as an option) and making sure we got out of the house and did things. By the time she and her dad moved back home she was keeping up on 6 mile hikes with me, no problem. Granted i've seen recent pictures and she's put some of it back on much to my chagrin, but at least now she tells her dad that she wants fresh fruit and veggies (which forces him to buy them) and she won't willingly eat fast food, which forces him to cook at home and ultimately leads to healthier options. He's been emailing me lately asking for recipes of meals that she's requested, and he's teaching her how to rollerblade because I sent her some for her birthday.
It comes down to this: YOU, as the adult, have control over the activities she partakes in and what she does. YOU have the control over what she eats. Clear out your fridge of everything that isn't healthy and replace it with better things. Lowfat yogurt, sugar-free trail mix, natural juices or flavored waters instead of soda, cookies, chips, etc. Stop letting her graze and snack before meals, quit letting her spend all of her time doing nothing. If she insists there is nothing to do, give her chores! I push-mowed, washed dishes, polished silver, precision painted mouldings, cleaned gutters, edged lawns, pulled weeds, washed cars, cleaned oil spots off the driveway, raked mulch, etc whenever I had the gall to tell my mom or dad that I was "bored". I guarantee you she'll find a way out of the house after that, be it taking the family pets out multiple times a day, or going for a walk or bike around the block or to the library or something. You also need to establish proper portion sizes and start talking to her about the road she's headed down. It's just going to get harder for her to lose as she gets older because those habits will already be ingrained into her. And you are running a real risk of her developing diabetes or heart disease in her late teens if you let her keep this up.
I'm wishing you the best. Put your foot down and be the boss. The changes won't just benefit her, but the whole family.
