Tom explained: ‘At the end of 2011 I was told that I would have to lose weight by our performance director at British diving, and that I was overweight and that I needed to look slimmer, leaner and more like I did in 2008.
‘It was the first time where I felt that I was being looked at and judged not for how I did in the diving pool, but for how I looked.

‘I took then some quite drastic measures to make sure that the food did not stay in my stomach let’s put it that way.’
He candidly went on: ‘A rational person would know that I wasn’t fat, but that was all that I could think about in the build up to the Olympic Games. I had a diary that I would write in, and at the top of it, I’d write the date and my weight.
‘I was kind of left on my own devices, and kind of left with that struggle by myself, because even when I was having these meetings with my sports psychologist, I didn’t know how to bring that out, because every time I said it out loud, I knew it felt silly.
‘But in my head, it was the biggest thing that I would always think about every day, every time I made a decision about what I was going to eat, if I was going to eat it and then get myself so hungry that I would end up eating so much and bingeing to the point where I was then so guilty that I then had to do something about that.’
The gold medallist admitted that he felt ‘very alone’ and unable to talk to anyone about his struggles, because he felt as though men weren’t supposed to have mental health issues.
Tom said: ‘I still feel like ashamed talking about it now, because, like, once you’re on the other side of it, it seems so easy just to stop and ask for help, but when you’re in it, you feel like you can’t be helped.
‘Guys didn’t have eating disorders. Guys didn’t have any problems with their mental health.
‘Guys were meant to be these macho things that get on with anything and you just keep going. I was not that, I didn’t know who I could talk to.
