According to People, the reality star has lost more than 20lbs and showcased her new figure at the New York premiere of comedy Grown Ups.
She told the magazine that she believes in "portion control" and doesn't deprive herself of anything: "If I want pasta, I have it for lunch instead of for dinner. That's all. If I want a piece of cheesecake, I have half instead of a whole."
The star also revealed that she exercises regularly and has cut down on soda, juice and caffeine, but admitted to having a weakness for mojitos.
"[I feel] so much better," she added. "I love it... I always felt uncomfortable in my clothes. But now I’m good."
The Real Housewives Of New Jersey continues this Monday at 10pm on Bravo.
