Bill Cosby, serving three to 10 years for the drugging and sexual assault of a woman in 2004, has chosen a healthy diet plan to lose weight. According to a report by TMZ on Sunday, the disgraced comedian has stopped carbs and sweets in order to maintain a healthy lifestyle while in prison.

“Since the day he was sentenced for sexual assault, Cosby has sworn off unhealthy foods. We’re told he hasn’t touched bread, desserts or any of the prison menu items filled with starch and sugar," Andrew Wyatt, Cosby’s spokesperson said, according to TMZ.

Cosby has stopped having coffee and his diet mostly includes fruits and vegetables.

The 81-year-old's representative told TMZ that Cosby did not want to turn into an overweight inmate or end up with diabetes because of which he decided to follow the healthy routine. Other than following the diet, the comedian is also exercising on a stationary bike and is doing crunches to reduce the extra pounds. Wyatt said Cosby's lost a considerable amount of weight since he got into prison, going from 220 pounds to 187 pounds.

Cosby, who is said to have taken his role as “America’s Dad” seriously in prison by speaking to his fellow inmates in a fatherly way, filed another appeal in June of his sexual-assault conviction as he serves time in the SCI-Phoenix prison. Cosby’s legal team filed the motion claiming that five of the women accusers should not have testified at his second trial. He also claimed that the judge who denied him bail release during his appeal did so because of "racial hatred."

While Cosby continues to fight for his release, it seems he is enjoying his time behind bars. According to Raheem Shackleford, a former inmate at the prison, he even laughs and jokes with his fellow inmates.

“As soon as he exits the cell, comes off the unit, he’s just Bill Cosby. There’s nothing different,” Shackleford told the Inside Edition in May.
