The Sliding Doors star is known for her healthy eating, but she also confesses to indulging and eating whatever she wants as she juggles her work with her responsibilities as a mother-of-two.
However, Paltrow forces herself to undergo a 12-week detox programme whenever she starts to feel sluggish.
She tells Harper's Bazaar magazine: "I'll wake up exhausted; I can feel my adrenal cortex being really high. When I get into bed, my heart will pound, my skin won't be good, I'll feel cranky, and then I'll just know it's time."
The actress kicked off 2012 by embarking on a big cleanse and she will remain on the diet programme until the end of March.
She says: "I have a lot of inflammation in my system, so I'm not having anything I'm allergic to - no gluten, no dairy, no sugar."
