The Australian has created a five minute video that briefly documents her own struggle with body image, explaining how she has loathed the sight of herself for her whole life.
'I thought to myself: how am I gonna teach my beautiful daughter to love her body, if her mum can't do the same?'
'I thought to myself: how am I gonna teach my beautiful daughter to love her body, if her mum can't do the same?'
It was this that spurred Tanya into action, and she set about getting the 'perfect body' by weight training.
'I entered myself into a body building competition. And I did have the perfect body, or near enough…and you know what? Nothing changed about how I felt about my body.'
The result of Tanya's experiment was that she realised she had to change the way she felt about herself from the inside out.
Everytime she looked at herself in the mirror and started to tell herself she was fat or disgusting, she stopped.
'I had to fake it until I made it' she says, but after a slow start Tanya began to feel better.
Tanya then made the brave decision to release before and after photos with a difference. Rather than showing herself larger before and thinner after - she showed her bikini clad, body builder self as the before, contrasted with her relaxed, untanned, natural frame after she stopped all the training.
Tanya is now campaigning to raise money so she can create a full length documentary - Embrace - which will encourage women to think more positively about themselves.
'We're not encouraged to love our bodies unless they conform to one idea of beauty…but beauty is so much more. We need a different currency for beauty.'
