I always wondered if that was the case. It makes sense. He was extremely lean for the majority of his life and then started to put on a lot of weight around Glimmer Man and I don't think it was just because he got too comfortable with his success. Of course, he proved he could overcome it by slimming down for Exit Wounds, but it's his business.
I love Seagal but I don't buy it. He became lazy, he doesn't workout & doesn't care about dieting at all...and eats A LOT, you can tell in the Season 1 or 2 of Lawman that he stopped frequently to eat, always a lot of carbs.
