For five years, Alyx Hoge has struggled with her weight.
"It wasn't just the way I looked," she said. "I really felt like I wasn't active enough -- I couldn't run as fast as anyone that I knew. I kind of felt awkward, and I wasn't very confident."
This summer, Hoge is changing that. She started a healthy living plan and so far, she's lost 21 pounds.
Yvonne Sanders with Slimming World is helping Hoge.
"Food and inactivity combined are the things that are causing the obesity epidemic in children that we have," she said.
Sanders said parents should get rid of the chips and cookies and stock their home with fresh fruit, veggies and meat. Hoge said the changes are easy.
"It’s not hard to stick to," she said. "It's real food -- you can eat what you want, mostly. And if I need something like chocolate, I just say, 'I’m going to have some chocolate today.'"
The other part of the equation is exercise. Sanders said it's easy for kids to spend an entire day in front of the TV or computer, so it's important for parents to get involved in helping their kids stay active.
Hoge said her whole family is now living healthier, and it's a lifestyle change they're keeping for good.
"It feels great," she said. "I run faster, I talk easier, (and) I’m more confident."
