Tons of celebrities, from Beyonce to Gwyneth Paltrow, Ashton Kutcher and Demi Moore, have said they do cleanses like the “master cleanse.” Beyonce says that’s how she shed 20 pounds for “Dreamgirls.” What’s a cleanse? Basically you consume little more than lemon water, cayenne pepper and maple syrup for a few days — sounds fun, doesn’t it? (Source: ABC News)

Reality Check: Most doctors say cleanses aren’t necessarily harmful, but also not necessary for your health (our bodies are perfectly capable of flushing out toxins on their own, thank you very much). And while you might lose some weight initially, you’re likely to gain it all back once you start eating normally again. Simpson recommends, “avoiding crash diets. Instead of cutting back foods, try looking for nutritionally balanced foods — complex carbs, healthy fats, antioxidants and water-packed foods.” She also suggests trying a nutritional supplement so you still get your vitamins while restricting calories (she’s a fan of the GliSODin Skin Nutrients Line).
