'Cake Boss' Star Buddy Valastro Shows Off Dramatic Weight Loss -- See the Pics!

The baking pro also shared the secret behind his dramatic weight loss.

Cake Boss star Buddy Valastro is sharing his dramatic body transformation and revealing how he shed the pounds.

The 41-year-old baking whiz took to Instagram on Monday to post a pic showing him posing with his wife, Lisa, while looking slim and healthy in white pants, a patterned shirt and gray jacket.

“A lot of people have been asking me how I’ve slimmed down lately so I just wanted to share that I’ve used the Optavia program,” he wrote alongside the photo. “I’m not being paid to say this and it should be noted that I think everybody is different and you should do whatever suits you, but this is what I’m doing and I’m very happy with the results so far!”

Valastro also shared a pic of the couple at the beach over the weekend.

“Down the shore with my beautiful wife! Does it get any better than this? @lisavalastro4,” he wrote.

The Optavia program aims to instill good habits, like drinking an extra glass of water each day, into users lives, as they work towards a healthy weight and ongoing healthy lifestyle, with the help of coaches.

Valastro’s transformation is evident when comparing his latest post with a photo he shared with his late mom on Mother’s Day.
