But industry observers believe the decision might have something to do with the former Man vs. Food host's social media controversy earlier this month.
Richman set off a firestorm of criticism when he used the hashtag "#thinspiration," a term often used in pro-anorexia and pro-bulimia communities, to caption a photo featuring his 70-pound weight loss.
He responded with a series of defensive attacks.
"Grab a razor blade and draw a bath. I doubt anyone will miss you," he told one commenter.
Richman apologized Tuesday for his remarks.
"I've long struggled with my body image and have worked very hard to achieve a healthy weight," Richman told ABC News.
