Reality TV star Adam Richman learns from social media rant

Reality TV star Adam Richman said he has learned his lesson after a social media tirade led the Travel Channel to delay the premiere of his new show.

"You just have to swallow it and just move on. There is simply no upside to engaging in faceless disagreement or hatred," Richman told CNBC's "Squawk Box" from the Dublin Web Conference.

Earlier this year, Richman lashed out after being criticized for pairing an Instagram photo depicting his weight loss with a hashtag that is seen as encouraging eating disorders. He responded to comments with a series of profanity-laced tweets and suggested one critic commit suicide.

He acknowledged he not only hurt the Travel Channel and his own brand, but caused his crew to go without work and deprived the restaurant owners slated to appear on his show of national exposure. Richman was scheduled to launch a program called "Man Finds Food" in July in which he would have visited restaurants around the United States.
