Better than Weight Loss Surgery?

There's an encouraging article today in the Los Angeles Times about scientists working on a procedure that would be much safer than weight loss surgery. It involves disrupting the vagus nerve. The vagus nerve tells us when we're hungry, it's the communication path between the stomach and the brain. See the full article here. Here's an excerpt;

WEIGHT loss surgery works, but is so invasive and has such unpleasant long-term side effects that it's recommended for only a fraction of the obese population, and even many in that group are reluctant to undergo the surgery. In hunting for a simpler and safer alternative, researchers have zeroed in on a nerve that carries much of the communication between brain and gut.

Disrupting this communication, they believe, could lead to safe, effective and sustained weight loss -- mainly by cutting off signals from the gut that tell the brain it's time to eat....

Two different methods of disrupting the vagus nerve are now in clinical trials. One method, vagotomy, simply cuts the nerve and permanently disables it. The other, vagal nerve blocking, uses an electric current to periodically confuse the nerve and prevent it from transmitting signals. Preliminary results suggest that both methods help to safely reduce excess body weight by about 20% on average within six months of therapy.
