The force involved may be tiny, and result in a minute weight-loss, but that is exactly what has been witnessed, a very minute weight-loss when the bodies internal electric field 'switches off'. Gravity might not be the only force pulling us to Earth.
I know little of neuroscience, but could everyone have such a similar amount of power to generate this em field?
And aren't there people whose brains slowly fade from consciousness as they approach death? I suppose it would be irrelevant if the people were weighed a while after their death, but I'm still unsure of the EM theory. Perhaps I just don't understand it so well.
