„[Vegetarian lifestyle] made me feel great. I still feel young, totally healthy. I’ve fought in the sport for many years and I feel like it’s something that’s helped me tremendously. But I’ve never eaten meat, so I can’t compare the two and say, ‘This is what it does better.’ But all the people I know who have gone from eating meat to not eating meat say they feel much better.“
