The number of obese people has now surpassed the number of overweight people in the United States. Fighting this epidemic is on the forefront in the medical world. Now, a new, less-invasive procedure may give people who need to lose weight new hope.

Veronica Mahaffey was looking for a clean break.

"I lost 12 pounds in the first week," said Mahaffey.

It's the first time in her life she ever lost so much weight, so fast.

"I was just on no carbs at all. I just finished that," said Mahaffey. "I hate diet pills. I did South Beach and Optifast."
