Soccer is an intense game that requires constant physical activity. So that means the players have to have a diet that is going to help them get to where they need to be as athletes. William Akio is a professional soccer player in Canada, playing for Valor FC, and he wanted to show his YouTube audience what he eats in a day. No surprise, it's pretty healthy. But what is a surprise is that it also includes cereal! We're fans of that part.
