Brain surgery for weight loss?

That's exactly what a woman in West Virginia did.An article in the Times Of India titled "Woman has brain surgery to fight flab" says that the woman tried deep brain stimulation after trying everything else(diets,stomach stapling,etc). It is only the second such surgery performed and is a part of a clinical trial.
In the procedure, wires carrying electrical impulse were inserted into the region of the brain that controls the stomach and uses electricity to control her feelings of hunger and satiety.
For all that she has gone through,I just hope the procedure works!
