The How to Look Good Naked presenter is recently single and admitted that he is feeling "vulnerable" at the moment.
Wan told Now: "I am vulnerable at the moment. It's new, so it's not a great area for me to talk about.
"It's definitely affected me. Definitely. To what extent I don't know yet. It always takes a little while. The break-up process takes longer as you get older."
Wan admitted that he is scared of being alone and is eager to be in a relationship again.
"I am terrified of being old and single," he confessed. "I worry that I have created this world that has so many doors to go through to get to the centre of it that I worry I have run out of time, or keys, to give to people to get in there."
Wan previously spoke to Digital Spy about his weight battle, admitting: "I think I'll always have some form of body dysmorphia and I think I'll always have some form of eating disorder because it's a huge part of who I am now. But I've never been in a healthier and happier place with my body than I am now."
