6. Miley Cyrus
Back in the days, Miley Cyrus found out that she had both a gluten and lactose intolerance which made her adopt both a gluten-free and a lactose-free diet. It was because of this diet that she lost quite a bit of weight. It was also because of this that there were rumors about her having anorexia. Miley is happy and healthy and eats a well balanced diet.
