Time behind bars has apparently done Real Housewives of New Jersey star Joe Giudice some good.

Teresa Giudice revealed to Extra that her husband has lost a significant amount of weight within the first six months of his 41-month sentence.

“I talk to him every day, sometimes twice a day. He calls me and we email constantly throughout the day and I see him every week,” Teresa, 44, said of staying in constant communication with her husband.

“He’s lost over 30 pounds. He looks amazing! I can’t wait for him to come home. I said, ‘You’re not coming home until you have abs,’ ” she teased.

In October 2014, the Giudices were sentenced to prison – Teresa for 15 months and Joe for 41 months – for mail, wire and bankruptcy fraud.

Teresa said of her prison sentence: “We all go through tough times in life. Life is like a roller coaster. It’s not always peaches and cream. You gotta go through good times and bad times and it makes you the person that you are.”

And, indeed, 44-year-old Joe told PEOPLE in February that he planned to use his time away as reboot for his health after he developed the habit of drinking “a couple of bottles [of wine] at night” during Teresa’s 11 months in prison.

“I am not going to be able to drink for a while, which is good because I don’t even know when it’s been since I haven’t had a drink,” he said at the time.

“For a solid year with all this TV crap and socializing with people every day and going here and there you are constantly drinking,” he added, “so it will probably do me good.”

The Real Housewives of New Jersey airs Sundays (8 p.m. ET) on Bravo.
