Maintaining is tough and fast food is tempting, so we can't blame the guy!
Jack Osbourne, who looked to be a little out of shape, was spotted leaving a Jack In The Box in West Hollywood on Wednesday.
Jack's weight has been up and down his entire life, but just last month he seemed to be getting very serious about his body by starting an extreme fitness regimen used by the U.S. Navy Seals!
We hope he hasn't given up!
Check out more pics of Jack's junk food binge below!
