Assuming thats percentage, math suggests such an operation might turn him inside out upon crossing the zero % point, and re-expand the result to 88% of the original size.
Do not try this at home.
(Think transporter malfunction...)
Ha. You appeal to my inner nerd, goodman.
I think a good turning inside out might do him a world of benefit. Maybe the inertia of all that mass moving so quickly would cause the layers upon layers of loose blubber to be flung outward, away from the center. Think "big bang event". All that would be left is a normal sized husk of a human with VERY loose skin.
After months, maybe years of rehab, physical therapy, and skin sewing, he may even learn to function as a viable human being again.
Yea. Let's do that.
