Three weeks after the surgery, the voltage inside Poe's brain pacemakers was turned on. According to doctors, it will be several months before any weight loss is noticeable once the voltage is increased to the level required.
Yet four weeks after the surgery, Poe said she's already lost three pounds.
"When I eat, I get full faster," she said. "I just don't have the cravings like I used to have."
And she said she no longer has the urge to consume a whole liter of her favorite drink -- Pepsi -- every day.
As part of the study, Poe must keep a meticulous journal of everything she consumes, and doctors will carefully track her progress. If this proves to be the solution to what has been a lifelong struggle for Carol Poe, her surgical team believes it could and should become widely available, targeting the brain for the benefit of the body.
"If I have a craving it's just a little craving and it's not just a craving to keep eating and eating and eating it," she said. "My body feels different. I feel like I am more, I'm more satisfied as far as food goes. And … I feel better."
"This may be the tip of the iceberg," said Bailes, "And again open the door for clever people and brilliant researchers to look at what the other applications could be. I think we can't forsee some of those now."
