At 15-years-old, Lewis Breed weighed only five stone and was at risk of dying. Now, the 31-year-old is one of the best bodybuilders in the world, competing in the super heavyweight category, which demands a minimum weight of 16 stone.
The reason Breed - from Plymouth, UK - was so ill in his earlier life was because he was suffering from undiagnosed allergies, which were wrongly interpreted as an eating disorder.
After eventually learning that he was allergic to wheat, dairy and gluten, he cut such foods from his diet and his health went from strength to strength.

Now the father-of-six has won a string of international bodybuilding competitions and couldn't be further from the poor health he suffered as a teenager.
Reflecting on those dark days, Breed said: "I started to lose weight very quickly and I had every test under the sun, but the doctors could never find anything wrong with me.
"I was labelled as having an eating disorder.
"I was also incredibly uncomfortable. I was five stone and had a resting heart rate of 28bpm. I was just lying there, literally comatose all day long."
Now Breed now travels around the world competing - and eats nine meals a day.
He said: "I regularly compete in bodybuilding and most recently I just won the Ben Weider Worldwide Classic super heavyweight and I just won another show this weekend. In two weeks we will be heading off to Spain for another competition.

"I love the competition and especially the rewards when you do win but as well as competing, I've got a business and me and my partner have six kids between us.
"There is a lot to do - there's a lot of organising and I do enjoy it but you have to be dedicated.
"I exercise in the gym three hours a day every day and my diet is incredibly strict. I eat nine meals a day and they are full meals, that is hard work in itself."
In terms of his bodybuilding career, Breed thinks his peak is still ahead of him, but even when he eventually stops, he thinks he will continue with a similar diet to the one that turned his life around.
He said: "When I'm not competing I won't be so strict but I won't change too much because I've lived this lifestyle and it suits my allergies. I will still exercise every day and eat well.
"I have been doing this for ten years so waking up and eating chicken is no different to having a bowl of Coco Pops - it is the norm for me."
