Fans were shocked when Busta Rhymes revealed his body transformation in October after weighing 340 pounds at one point.

On The Messy Truth with Van Jones, Busta revealed that his transition to a healthier lifestyle was matter of life and death.

Busta said that a combination of weed, cigarettes, and alcohol, along with a prescribed medication for his throat, contributed to his weight gain. Busta said that during a doctor visit, polyps were found developing in his throat and he was told his body’s air supply was only at 10 percent.
