Jared Leto

''I'm pretty healthy - I've been that way for a long time. Twenty solid years of eating vegetarian/vegan and taking care of myself. That probably helps the preservation process.''

The American-actor, singer-songwriter and musician became vegetarian when he was a teenager and a few years later, after learning about the presence of pus in dairy products, switched to a vegan lifestyle. Leto is the lead vocalist, multi-instrumentalist and main songwriter for Thirty Seconds to Mars, a band he formed in 1998 in Los Angeles, California, with his older brother Shannon Leto. Their debut album, 30 Seconds to Mars (2002), was released to positive reviews but only to limited success. The band achieved worldwide fame with the release of their second album A Beautiful Lie (2005). Their following releases, This Is War (2009) and Love, Lust, Faith and Dreams (2013), received further critical and commercial success. As of September 2014, the band has sold over 15 million albums worldwide. Leto has also directed music videos, including the MTV Video Music Award–winning "The Kill" (2006), "Kings and Queens" (2009), and "Up in the Air" (2013).
