On diet: "I live by a rule book of eating alkaline.
And then I'll cheat when I want to, but I sort of make that my go-to unless I'm out at a great restaurant.
I'm a bit of a foodie, so I can't cut out the things that I love, so I just make sure that on a daily basis I eat very alkaline.
So no meat, no dairy, no gluten, I try to stay away from sugar.
But then I could be at a movie theater and throw down on some popcorn and milk duds or at an Italian restaurant and I'll have my pasta.
So I try not to make it about dieting, I try just to make alkaline my normal and then have fun." she revealed on Harper's Bazaar.
On exercise: "I change my routine. I change my look. I change my mind," Hudson said on SELF.
And when it comes to exercise, she says, "I really switch it up."
Her only fitness regimen, it turns out, is not having one.
I'll do Tracy Anderson, I'll do Body by Simone, I do everything," Hudson says.
Your body is constantly adapting as it moves. Still, when she really wants to whip herself into shape, she focuses on Pilates.
