Besides spending hours at the gym, Mahhi Vij believes in following a healthy diet to maintain her body. She says, "I'm always reading and keeping a tab on my food intake." She adds that she constantly experiments with her diet.

Mahhi Vij is married to TV actor Jay Bhanushali. The couple had a hush-hush wedding in 2011, but made it public only a year later. Two years later, there were reports about trouble in their paradise, but in early 2014, they put speculation to rest by exchanging wedding vows yet again while holidaying in Las Vegas.
