Chris Moyles has revealed he has an issue with body dysmorphia.
The radio DJ has lost six stone through working out and watching what he eats, going from 18 stone to 12 stone.
But he admitted he still struggles with concerns about his appearance at times.
Opening up to Ross Kemp during a chat on his podcast, The Kempcast, Moyles said he was feeling “bloaty” and “really big at the moment”.
The star, 46, said he relaxes his fitness regime over the weekend and puts on a few pounds then gets back on track during the week.
“So at the moment I’m feeling a bit barrelly, my body dysmorphia is kicking in,” he said.
“And by Friday I’ll be like, I’ll probably look exactly the same but I’ll feel, yeah, feeling good.”
Discussing his routine, Moyles said: “I know my body really well now, better than ever in my life, and I’m still leaning and I’m lucky that I have a trainer who is a nerd about this stuff and he’s got a very similar metabolism to me, which is that of a JCB.”
He went on: “I will, and people don't believe me, but I weigh myself five, six days a week maybe, and I know you shouldn't and I know it's not for everyone, but the reason I do that is so I can learn about how my body works.
“I will train Monday, Tuesday, Wednesday, Thursday, Friday and I will watch what I eat and I'll eat very little.
“Today I’ve had literally all but nothing to eat today and I’m great, I do intermittent fasting and I'll eat at 6.30pm or 7pm and I'll be fine.
“But I need to do that from the weekend that I just had.”
According to the NHS, body dysmorphic disorder (BDD), or body dysmorphia, “is a mental health condition where a person spends a lot of time worrying about flaws in their appearance. These flaws are often unnoticeable to others.”
