Stylist Roxanne Parker, 34, (www.roxanneparker.com) decided to become vegan after ending up in a hospital bed:
"Over the past two years, I've slowly changed to a fully plant-based vegan diet. It all started back in 2012 when I fell ill.
"After countless tests, I discovered that my bladder was over twice the size it should be, but the doctors couldn't tell me why.
"Desperate to get my health back, I decided to ditch dairy and meat from my diet. The result was nothing short of miraculous. Within a month, my bladder had shrank to a normal size.
"Since turning vegan, I have more energy and friends have told me that I look younger, too.
"Typically, breakfast might be porridge with almond milk topped with seeds and fruit, lunch could be a lentil salad dressed with vegan pesto and dinner, a coconut milk-based green curry with brown rice.
"Last summer I started posting photos of my vegan meals on Facebook, and the reaction has been amazing. People are always messaging me for recipes!
"You can be vegan and still be unhealthy, tucking into crisps and fizzy drinks, but what's the point? You will only look and feel terrible.
"Some people ask me if my diet is expensive, but I can honestly say I've saved a fortune by becoming a vegan.
"More importantly, knowing that I was able to cure myself through nutrition – and inspire others to make changes in their diet along the way – has been a hugely empowering experience for me."
