The average person is bound to feel a little guilty after some holiday overindulging, and maybe even resolve to lose weight in the new year. But Gwyneth Paltrow's post-holiday binge is far from ordinary. Her seven-day elimination diet consists of liquid meals and snacks (think room temperature lemon water, coconut milk and the occasional handful of berries and almonds). In her newslettter, she doles out detox advice: "I like to do fasts and detoxes a couple of times during the year, the most hardcore one being the Master Cleanse... It was not pretty. Or easy.
