Rick Ross -- Carb Danger Behind Bars

Rick Ross had a close call in jail Wednesday ... in mortal danger of gaining back some of the pounds he lost.

As TMZ reported, Ross was busted for pot possession near Atlanta and was hauled off to jail. As the hours ticked away, Ross got hungry. The challenge: eating something that did not compromise his recent 100 pound weight loss.

The 2 slices of turkey made sense. A slice of cheese never killed anyone. The juice pack is loaded with sugar, but it's small. Ditto the "Oreo-like cookie."

But then comes the starch ... a staple in the pokey. Rick was tempted not once, not twice, but to 4 slices of bread.
