An interview with Women's Health revealed that Paltrow recently went on a goat-milk-only cleanse for eight days straight. No crunchy veggie salads or detox granola bars. No coffee-free warming lattes. Not even bone broth. Goat's milk contains less lactose than cow's milk, and may help your body better process iron, calcium, phosphorous, and magnesium, according to experts. It's also been reported to reduce inflammation, boost your immune system, and reduce blood pressure. Apparently, however, Paltrow went on her milk-only diet to fight parasites in her body.

Kim Kardashian was so intent on her Met Gala look being perfect that she went on the 10-day Sunfare Optimal Cleanse beforehand, a cleanse that requires liquid meals for three of the 10 days. “I was actually really nervous about wearing the dress because I did a cleanse a couple of weeks before and lost six or seven pounds. At the final fitting, I was worried it wouldn’t fit. When I tried it on, though, it fit like a glove. It was perfection!” she wrote on her subscription-based website and app.

“Since drinking enough water every day is a huge part of my wellness regimen, I have big pitchers at home infused with healthy ingredients,” she wrote on her app. “Studies show that drinking 8 to 12 ounces of filtered water with fresh lemon first thing in the morning helps jump-start your metabolism and detox your body, while mint and ginger are effective in keeping your immune system strong.”
