Former NBA player Glen "Big Baby" Davis seems to have Devin Grosvenora surefire plan on dropping some pounds while he is in prison.

On Thursday, Davis was sentenced to 40 months in prison, three years of supervised release and ordered to make $80,000 in restitution, plus participate in financial management classes and drug testing mandatory for his role in an insurance that milked $5 million from the league's health and welfare benefit plan.

Davis was accused of submitting fake claims for dental work that was never done and lying about his whereabouts during the false procedure, which authorities quickly proved through his cell phone's geolocation.

After his sentence, Davis addressed on Instagram Live and whoever was within earshot outside of a New York City courthouse, joking about his sentence and detailed his diet plan.

“Imma be swole, though. I swear to God I’m about to get in so much shape. On God," Davis said. "That's what God say, I'm going to stop you eating hamburgers imma put you in jail. You don't want to stop eating hamburgers and Cheetos? You're going to jail. So now, imma become The Rock.'"

During his playing NBA playing days, Davis, who played for the Boston Celtics, Orlando Magic, and Los Angeles Clippers, regularly tipped the scale at 290 pounds on his 6-foot-9 inch frame.
