They say that the best revenge is a great body— and apparently Paul Nassif agrees! 

Since divorcing Real Housewives of Beverly Hills star Adrienne Maloof, 51, in November, the plastic surgeon has dropped 19 pounds, and reveals his weight loss secrets to In Touch.
 
“I've lost about 19 pounds and I do two things,” Paul tells In Touch at the Beverly Hilton Hotel during the unveiling of the Aqua Star Pool Redesign by Estee Stanley. “One: calorie counting— calorie in and calorie out, that's number one. Two, working out six days a week. I got into running and ran 10.15 miles last week.” 
 
 
And now that he’s a single man, he has more time to dedicate to working out. His next exercise challenge? 
 
“I'm gonna run a half marathon in Napa in July,” the reality star, 50, admits. “Plus all these boot camps and lifting and all that stuff.”
 
While his ex has been busy with on-and-off boy toy, Sean Stewart, who is twenty years her junior, Paul firmly tells In Touch: “Right now I’m not dating at all.” 
 
 
The slimmed-down father of three is currently in the middle of a custody battle over his three boys — Gavin, 9, and twins Christian and Colin, 7— with Adrienne, but is hoping that he’ll at least get to spend time with them for Father’s Day.
 
“Hopefully my kids will all come out to brunch with me but I don't know,” he tells In Touch
