Singer Tom Grennan has said having therapy has helped him with issues around body dysmorphia, calling himself his "own biggest critic".

Speaking on You About? - the performer's BBC podcast with his best friend, broadcaster Roman Kemp - Grennan spoke about how it affected him.

"I definitely have body dysmorphia," he said. "I'm always constantly thinking I am bigger than I am. Or I'm always pinching my belly. It's not a healthy mindset at all, and I fully admit that."

Eating patterns and gym training habits, he noted, can have a big impact on his mental health. "Sometimes I wouldn't be training for the purpose of staying fit," he added.

"I'd have a binge with eating and then I'd be like, 'I need to go and train now to make sure these calories or this food isn't put on to me - which is an unhealthy way of being."
