OK, I have a big event in two weeks and I really need to lose the weight fast. I heard you can drop 20 pounds in 10 days with the Master Cleanse Diet-also known as the Lemon Diet and so forth. Beyonce even used it. However, I am nearly 17 years old, so is it safe for my age? Apparently, it's designated for nearly everyone. And I've always maintained a healthy lifestyle, I do exercise everyday. But I like to eat carbs unfortunately...so is it healthy for a 16-17 year old?
