Only 60.
I'm pretty sure it was 100... didn't he gain back 40 lbs on top of the 60 he lost? Either way, that's a lot of weight to be losing and/or gaining in so short a time.
And "just to see if I could" is sort of a strange thing to say about it. Nothing against him, though. I'm actually a pretty big fan myself. I loved Equilibrium. It's a little worrying given what little I know of his personality and history, is all.
