Jared Leto

Unlike a lot of his fellow vegans, Jared Leto refused to give up his healthy habits in order to bulk up for a film role. According to Ecorazzi.com, the Best Supporting Actor Oscar winner gained weight for the upcoming Suicide Squad by eating only vegan products, just more often than usual. The 44-year-old singer and actor also credits his youthful look to his meatless lifestyle, "Twenty solid years of eating vegetarian/vegan and taking care of myself. That probably helps the preservation process."
