Elsa Pataky "cleans her system" with vegetable juice.
The 36-year-old beauty - who has daughter India Rose, 23 months, and twin sons Sasha and Tristan, five weeks, with husband Chris Hemsworth - favours a "super good" healthy liquid concoction when she feels the need to detox.
She explained: "The juice I like to drink once in a while and that helps me to clean my system is made with a blender: an apple, a carrot, some celery with the green leaves, a lemon without peel. Once it's done, you add a few teaspoons of olive oil. Super good."
The Spanish star also admitted she will be waiting a while before she returns to the gym, having given it "two long months" before exercising again after the birth of her daughter, on the advice of specialists.
She wrote in her blog for Spain's Glamour magazine: "In my case a specialised post partum physiotherapist recommended not to work my abs not work until they were totally joined again.
"As you know, when you're pregnant the abdominals separate as the belly grows. So you have to wait for your abs to return to its initial position before you start doing ab work or otherwise there may be a lump, like a belly that never goes away. I started working my abs two long months (after delivery)."
