But it appears that the Princess of Pop - and life in the spotlight - has changed all that.
The William Morris Endeavor Entertainment talent agent, 39, has lost around 50lbs since meeting Britney Spears, insiders tell America's Us Weekly.
"He eliminated carbs from his diet," a friend states.
"He’s been using a workout device that he calls his "miracle product."" The source didn't reveal just exactly what his secret fitness weapon is.
"We love to work out," Britney told Ryan Seacrest in an interview. "We do stuff together like that. We take walks."
As hard as it may seem to believe, Trawick was never in the great shape that he’s now. In fact, he was once heavier and with zero definition. Now Jason has killer abs! Don't you think?
