If he could lose another 50lb+ he would be back to Giant weight when he debut in WCW, I think he was around the 350lb mark back in 1995, so he's currently 68lb short of this but if he could/does lose that bit extra, it could prolong his career. I read he was having severe trouble with his knees to due to the massive weight he was carrying before the weight loss, plus I think he could be back in the title picture before long, and I loved to see him in debut Giant shape again, he was a killer back then.
I know it doesn't mean much saying this, but I'm very proud and impressed that he stuck with his diet and lost that much weight. I've always been a Big Show fan and in December of '06 he looked really bad and out of shape. I'm really glad he's lost most of it.
