The actress explained, "I stopped dieting when I figured out that you just have to eat regularly and properly within moderation."
With the news that if you yo-yo diet, you are more likely to be overweight than if you didn't diet at all – it seems Jen is one step ahead.
"The fads are too much, the fasts, when you hear people saying: 'I'm going on a cleanse,' it's just so bad for your body," says Jen.
"I think it's really about - honestly, this is going to sound so silly - going in the sun for 20 minutes a day is really important, vitamin D, because we are now having a vitamin D deficiency because of all the SPF."
The bride-to-be also believes that nothing beats being positive, "And I think being happy and smiling and laughing a lot."
We bow to you lifestyle yoda.
