On this first week back to school, one Houston youngster headed back to the books for a new school year with a new body — she's 40 pounds lighter.

So what's the skinny? How did Isabelle Finegold manage to lose that much weight?

The eighth grader went to the six-week Wellspring Weight Loss Camp over the summer in San Marcos, Texas.

Isabelle used to weigh 215 pounds. She tried over and over to lose weight and failed — until now.

"I really didn't like myself," Isabelle, 13, said. "I was made fun of a lot. So it was really hard."

Part of the program requires parents to attend the camp for three days.

"I lost 24 pounds. They taught me about cooking, about monitoring, about portion control and exercise," Isabelle's mom, Susanne Brody, said.

When mother and daughter returned home with new bodies, it was time to give the refrigerator and pantry makeovers as well — they had to empty their house of all fatty foods.

"Every single item. I emptied the whole house out. Got rid of every product I had in the house," Brody said.
