Alicia Silverstone says her meat and dairy-free diet is the reason behind why she still looks much the same as she did over 20 years ago in her breakout film, Clueless. When she was 21, she saw a documentary about how animals were raised and slaughtered. She said, "I just took a look at my dog and said, 'If I'm not willing to eat you, how can I continue to eat these other creatures that have the same desire to live, are just as funny, just as cute as my dogs?' Once I went vegan, I lost the weight I wanted to lose, my nails were stronger, and my skin was glowing. I feel great and I look better now than I did [before]."
