The 70 year old who looks like THIS - because she gave up sugar

It was nothing for me to have half a cheesecake for breakfast

At 70, mother-of-three Carolyn Hartz is often mistaken for a woman half her age, having maintained an enviable bikini body for nearly 30 years.

She says her secret is simple - she cut sugar from her diet. Carolyn is a self-confessed former sugar addict and used to regularly feast on sweets and cakes. However her life changed for the better after she gave up sugar 29 years ago.

She used to eat biscuits and chocolate galore ("It was nothing for me to have half a cheesecake for breakfast") until she got a health scare when she was diagnosed with type 2 diabetes: "That frightened me and fear... when you're frightened of something you should change. And I did change because I didn't want to be unhealthy."

Now Carolyn is completely sugar-free after going cold turkey, and doesn't even satisfy her sweet tooth with artificial sweeteners: "I don't drink anything light, I don't think they're good for you."

She joined us today live from Perth in Australia, to show us that amazing physique and reveal why she believes that going sugar-free can help transform anyone’s life. Watch what she had to say above.
