Kelly Preston: Organic Liaison helped her lose 39 pounds

kelly-preston-john-travolta-getty.jpg Kelly Preston has had a pretty dramatic weight loss since giving birth to her son Benjamin a year ago. She tells People that after having a baby at 48, she wasn't sure her body would bounce back. But she actually now has gone past her pre-pregnancy weight.

"I lost 39 lbs., have more energy than I had 20 years ago - and I feel amazing. I'm going to be turning 50 next year - holy s***! Hey, 50 is the new 30," says Preston.

She credits her success with playing tennis and of course chasing after a toddler, but she also says the Organic Liaison program developed in part by close friend of husband John Travolta, Kirstie Alley.

"I was so excited when my best friend created Rescue Me," says Preston.

The Organic Liaison plan says it helps "reduce cravings, boost natural energy, promote relaxation, and support rest," according to the website.

Kelly also says they've just had a celebration in the Travolta household, which has been recovering from the loss of their 16-year-old son Jett in 2009.

"We just celebrated Ben's first birthday. I can't believe it's already been a year," says Preston.
