For years, John Daly was known on the PGA Tour as one of the fattest and most unapologetic guys around. However, as his career yielded less and less in the way of results, his weight ballooned in the early-2000s, forcing Daly to receive lap-band surgery for the sake of his health. He was able to get below 200 lbs at one point as a result of the surgery but, as you can see from the picture above, he hasn't had much trouble putting any of that weight back on.
