Without a doubt, celebrity diets and weight loss work for some.
Other stars, though, have found that the best diet is none at all!
Having weathered the highs and lows of several eating disorders, actress Brittany Snow has sworn off dieting and personal trainers!
"I'm done. I canceled my trainer," Snow, 22, said over the weekend at Stride Gum's Longest Day of the Year party in West Hollywood.
"I refuse to do the whole diet or fitness thing anymore. I just go and have fun. I know what I like, what makes me feel good, and that's what I do."
Brittany Snow has had anorexia, exercise bulimia, depression, and body dysmorphic disorder as a teen - once falling to a Kate Bosworth-esque 85 pounds.
But the cute actress credits fellow star and friend Sophia Bush for helping to coach her on her body image issues and now is doing better!
