Ear STAPLING?
Sounds painful, but it might not be that crazy.
Supposedly there is an accurpressure point on the earlobe that can help reduce appetite. But I've just heard of wearing something on the earlobe (not 'stapled' to the earlobe, more like bent around it?, or a bb taped on the earlobe) and squeezing it when you get the urge to eat when you don't really need to.
