The singer vowed to get serious about being healthier a few years ago after realising how much rubbish she was eating.
Jane, 58, took part in Sugar Free Farm and began making small changes to her diet - but it was just cutting out one food group in particular that helped speed up her weight loss process.

She explained to Express.co.uk how she managed to lose four stone by cutting white carbs, like white flour or white pasta from her diet.
The popular singer is currently showing fans around her hometown for new series My Yorkshire for Channel 5, reports The Mirror.
Sugar Free Farm followed celebs as they attempt to live on a sugar-free diet and Jane carried on with it after it ended.
Now her body is "detoxed", the singing sensation reveals she likes to begin every day with a "green smoothie" -
Jane said: “I lost a stone and a half from taking part in the TV show Sugar Free Farm.
“I used to eat so much rubbish. I didn’t realise how much rubbish I used to eat. I’ve always loved a pie and I was very carbohydrate-led as I was always hungry.
“I ate far too much and all the wrong things. I didn’t realise that if you eat the wrong things, it doesn’t feed your body so you will want more.
“I like my life, and my schedule takes a lot of energy, but I was beginning to get quite tired and I was blaming it on age.
“I thought it’s just normal to have a big waist and a spare tyre because of my age.
“Then I was invited to take part in Sugar Free Farm and I met Angelique Panagos, the resident nutritionist.
"She said that I’d get a lot more energy if I just changed my diet and I looked at her with that ‘whatever’ look.
“But within two weeks I’d lost about 9lbs and I didn’t feel hungry. I always used to be hungry and was always snacking on something, but I don’t have any of that now.
“It’s because of a change in my mindset. I used to live to eat, but now I eat to live."
