A fitness writer from just outside Norwich has found success with a book born from turbulent times.

Ollie Matthews, 32, from Thorpe has become a best selling author on Amazon with his book The One Day Body Upgrade which launched this month.

Just 24 hours after it was released it reached number one in the Men's Health eBooks chart for America and Australia, and number two in this category in the UK.

Mr Matthews' journey to success has not been an easy one, however, with the sudden loss of his father to a stroke when he was fifteen and the bullying he endured at Hellesdon High School triggering a period of comfort eating that lead to obesity.

'I began comfort eating after I lost my dad,' he said, 'and by the time I was around 21 I weighed about 270 pounds.'

The now fitness writer and personal trainer turned his physical health around while still in his twenties and, by taking up working out at the gym and carefully planning his diet, he lost just under 100 pounds.

He said this time was not necessarily positive as though his weight became healthier it was easy to get obsessive about food and exercise.

'I think it was a case of feeling like I couldn't control what happened with my dad but I could control what went into my body and so I did get a bit too preoccupied with that and it became unhealthy.'

Now in his thirties and four years into a successful full time fitness career, which has included working with Taylor Swift's former manager and a number of professional athletes, Mr Matthews is all about a balanced approach.

This is exactly what he promotes in The One Day Body Upgrade - a book named after the idea of taking things one day at a time and careful not to neglect mental health in the quest for improved physical health.

'My dad died from a stroke because of the amount of stress he was under. Stress kills. He put providing for his family first above looking out for his own health and a lot of men do.

'It's my mission to make sure that my dad didn't die for no reason. If I can help even one child avoid going through what I went through then my days have been well spent.'
