Mike Bushell was completely stunned after seeing a side-by-side photo revealing his weight loss on Strictly's It Takes Two tonight.
BBC host 53 has become the seventh celebrity to leave the show over the weekend with professional partner Katya Jones.
Speaking to Rylan Clark-Neal after his departure, Mike and Katya watched clips of their time on the show.
Mike, who lost about a stone and a half, joked that he couldn't recognize himself from the beginning of the show.
Sharing a picture of him at the beginning of the show combined with a snap of him doing his last dance, Katya was surprised by the transformation.
She exclaimed, "Look at you!"
Rylan joked, "Nobody wants to get out of here being called a loser, but I'd accept it!"
The couple landed at the ball with Michelle Visage and Giovanni Pernice.
After the two pairs performed their dances a second time, all the judges chose to save Michelle and Giovanni, citing them as the "clear winner."
Despite this, Mike seemed happy and thrilled with his "awesome time" on the show.
He said, "I've had the most incredible 9 or 10 weeks since we started training. I've lost a stone and a half. I'm a 50-year-old man, I'm mentally keener, I can handle pressure situations. – thanks to the dances! That changed me completely and honestly, I won't stop dancing.
"My wife Emily supported me all the time and my daughters. My father is going to dance and my mother started Zumba – I want to thank all my family and the judges. I have all the comments around the house.
"Every moment was an absolute honor and joy. I didn't think it would go that far, since I've booked a hotel in Blackpool, so I'm still going. This amazing teacher, Katya, can't tell you the dedication that she puts it. She'd be the best sports coach ever, she makes you believe anything is possible. "
