Belo said that the programme became a hit on Channel 4 because it provided an outlet for a generation who were sick of "old and boring politicians".
Speaking about how Channel 5 can make the show a success again, he told the Daily Star: "Big Brother is the voice of the disenfranchised youth. That's how I felt at 19 when I did the show. There's all these old and boring politicians trying to tell us how to live our lives but that doesn't have anything to do with me day to day.
"The ordinary person who sees people in Big Brother talking about society, that's what's relevant to them. That is something they can connect with. It captures the imagination of youth. This is what the new Big Brother needs to do - tap back into what's relevant for young people."
Belo also reiterated his previous requests for Channel 5 to make the show "sexier".
"I want a sexy house. I want it to be pool parties, I want it to be drunkenness. I want them to have friendships, I want them to have relationships, I want to feel like I know them in and out by the end of it," he said.
"I've watched a lot of Big Brothers. I've watched the Swedish one, I've watched all the Australian ones. They all got naked in the Swedish one. On the first night someone did something naughty below the belt! Our one has been good - it's been notorious - but we need to compete with the rest of the world."
Celebrity Big Brother returns in August, followed by the traditional non-celeb run in September.
