Could become an astronaut and move to the International Space Station. No matter how much mass you have accumulated you will have almost no absolute weight and zero measurable weight.
Same thing can be accomplished with traditional Newtonian physics by using Nigel's trampoline. During the parabolic ascent and descent your mass is not exerting any measurable force and in that sense you are weightless. During the bounce your weight increases parabolically to a peak and then returns to zero as you leave the surface of the trampoline.
Using this second method you could also become aquatic and live under water where your weight will be reduced by about 90% due to the similar relative density of your new medium and your bodily mass.
