Vic Vogel, a personal trainer, is focusing on fighting childhood obesity in Oklahoma children. Vogel said the goal isn't necessarily to lose pounds, but to gain muscle, exercise and eat healthy.

Cheryl Lambert, the mother of three children, said it was norm for the family to eat at McDonald's, KFC and Little Caesars Pizza. When the family met Vogel, she knew their eating habits had to change. Vogel was set on curbing childhood obesity and passionate about helping Cheryl Lambert's 11-year-old Keylee.

"There was a little lack of self confidence that I felt in her," Vogel said. "I'm really about fitness, but I'm more about building up who you are as a person as part of that."

Vogel took on the challenge of getting the Lamberts in shape for free, and in just two months, Vogel's made a difference in the Lambert family's health.

Keylee, eight weeks after beginning a healthier lifestyle, is five inches smaller around her body and seven pounds lighter.

"My clothes are fitting way better now," Keylee said. "My pants are getting too big."

The transformation has changed her confidence, too. Keylee's more social and has even inspired one of her teachers to lose weight.

The healthier habits have also changed the way the rest of the family eats.

"If I can help Keylee to get where she needs to be now, she will sustain it," Vogel said. "She will be better off for it, and then consequently, I will have made a difference...it starts with one person."

The Lambert family said they'll continue to educate themselves on nutrition and exercise.
