Al Gore quietly went vegan in 2013 amid speculation about his motives, which he has so far chosen not to reveal.
While the former Vice President is well known for his stance on environmental issues, he had previously resisted making the switch to a plant-based diet despite pressure following the release of An Inconvenient Truth in 2006. “I’m not a vegetarian, but I have cut back sharply on the meat that I eat,’ he said in 2009.
Though Gore chose not to publicise the move, Forbes magazine let slip in December 2013, calling him a “newly turned vegan” in a piece listing wealthy potential investors in the eco-friendly Hampton Creek company. In giving up dairy, he follows his former running partner Bill Clinton who opted for a vegan diet in 2010 following heart bypass surgery.
While Al Gore has faced criticism from some quarters for not walking the walk in terms of his own environmental footprint, his work to raise awareness of global warming has established him as one of America’s most high-profile environmental activists and, now, vegans.
