Who is behind Calabaza?

Joe Espo is a food lover. Until about 2020, he was the guy asking for more meat on his plate. He had a change of heart after meeting his wife Laura, who is vegan. The documentary The Game Changers was influential as well.

Joe also has family heart health issues. And if there's one harsh truth about eating meat, it's that your heart has to pump more blood to digest it. This is why people get 'meat sweats.'

Joe is now a 'reducitarian' where he eats less meat. Since 2020, Joe has eaten about 100 pounds of squash per year.
