Terri Ann Nunns, 32, developed her own homemade diet to shed seven stones after having a baby - and is now raking in half a million pounds a year, according to the Daily Mail.
According to the paper, the Doncaster mother-of-three has swapped her one-bed flat for a mansion and is living a luxury lifestyle after inventing a diet plan when she piled on the pounds following two pregnancies in a year.
Terri-Ann used the elements of different diets that worked for her and lost seven stone - and after posting her photos online people were desperate to know her secret.
She set up a diet website which now has more than 53,000 members and is raking in more than £500,000 a year, meaning she can afford designer clothes and exotic holidays.
She told the Mail: 'It's like a dream come true. It's great being able to treat the kids without worrying and jet off to places we have never been.
'It's incredible to think all this happened just because I wanted to lose weight.'
Terri Ann first piled on the pounds after she gave birth to twins Angelo and Kelise in October 2005.
Kelise died soon after being born, and the heartbroken mum turned to food to help her through her grief.
Although daughter Aaleyah was born just 11 months later, the tragedy took its toll on Terri-Ann's marriage and she split from her husband in 2009 and her weight yo-yoed over the next two years, according to the Mail.
She tried a spate of diets but nothing worked as she tipped the scales at 15st 7lb.
But when she met second husband Michael in 2011 Terri-Ann decided to take matters into her own hands – and created her own three-step diet plan.
'Over a five month period I took inspiration and ideas from different plans and diets and decided to put them together by playing about with different foods allowed and not allowed.
'Through my food trials and research, I managed to lose 3st 4lb in 5 months,' she recalled.
She said: 'I couldn't believe it. For the first time ever a diet had actually worked and given me the body I wanted.
Terri-Ann posted pictures of her new look on Facebook – and was overwhelmed by people wanting to know how she did it.
She set up a website, called 'The Terri-Ann 123 Diet Plan' and by the time she gave birth to daughter Aamaya in January 2013 she was earning £40,000 a year.
'I decided to put the plan on paper and tell the world about it.
'Since sharing my plan through this Facebook group I have sold over 50,000 books to people worldwide and have thousands of people losing weight and keeping it off.'
Her diet website now has more than 53,000 members and is raking in more than £500,000 a year.
It has enabled the former PA to swap her cramped one-bed flat for a mansion, fancy cars, designer clothes and exotic holidays.
In November 2014 she and Michael, 27, bought their dream home – complete with cinema, gym and games room – and they married last year in a £30,000 ceremony.
Terri-Ann said: 'The lifestyle we lead is one we could never have dreamed of.
'But what really makes me happy is seeing the difference my diet has made to so many other lives.'
