Curious about his diet, I found this on a site called MuscleProdigy.com, from May 2012:
"Jean Claude Van Damme's diet routine consists of rice, bread, vegetables, and beans. Van Damme doesn't believe in eating anything "with a soul" in it. He will only eat meat on certain occasions, and if he does, he makes sure that it has absolutely no fat on it."That link also discusses his frenetic workout routine.
And from LiveStrong in 2011:
"Today Van Damme eats a lot of vegetables, stating that "plant-based foods are the best things for you.""I've been in this business long enough to know that what people say they eat is not the same as what they do eat. Even if someone is being up front with you, they often don't pay attention to amounts, or to how, and with what, something was prepared. Also, with someone whose career and ego depend on his looks, I'm going to guess Van Damme samples the supplements, and possibly the surgery.
Still, he's a good advertisement for a plant-based diet.
