After losing a whopping two stone, Lorraine joined Holly and Phil to promote her newest exercise DVD titled Brand New You.
The presenter said that she doesn't believe in restricting herself too much, and that her amazing weight loss is down to enjoying her fitness journey.
The 57 year old said that she used to be a 'big lass' until she turned her life around.
'I don't like diets - I don't think they work. I think it's all about portion control, not snacking so much and just being sensible.'
'I do like a chocolate bar... I keep a few of them behind the sofa cushions!' she laughed. 'I think a little bit of what you fancy in all walks of life is good!'
'Especially if that chocolate bar has coconut in it!' Holly replied.
'Well - that's one of your five-a-day!' said Lorraine.
She also told Phil and Holly that her main secret is to feel better 'in yourself'.

Lorraine previously spilled the beans on the secrets to her toned, healthy figure.
Speaking in an interview with Fit & Well magazine, the mum-of-one revealed, 'I don't weigh myself, but I'd guess I've lost at least a stone in the last two years, and I've gone from a good size 14 to a size 10.
'I'm so much more confident in my clothes. Yes, even a bikini!'
And how did Lorraine achieve her goals? By taking up a £5 dance exercise class, run by her now close friend Maxine Jones.
Lorraine does at least two of Maxine's classes per week (three if she has the time!) and says she feels like she's finally found an exercise that suits her.
'It all started when I was on holiday in Spain with my best friend two years ago. She said 'Come along to this class.' I said 'What? I'm on my holidays!' But I loved it, and when I came home, I looked for one near me. That's how I found Maxine.'

Lorraine admits that she found the first class hard - 'I didn't worry about anyone recognising me, I felt self-conscious because I didn't know the steps!' she laughs - but quickly found her groove.
'The class is in a church hall with a great bunch of girls. At my age, you don't go clubbing, but it's a great way to dance your cares away and listen to 'banging tunes', as Maxine would say. It's girl power, really!'
Lorraine carries her healthy routine over to her eating habits - she starts the day with a glass of warm water with lemon, which she says has improved her skin dramatically, and feasts on nutritious meals like porridge, salads and curries.
However, at the weekend, it's time for a treat. 'Everyone likes a glass of wine with their tea!' she says. 'I think it's good to separate the week from the weekend and have a bit of what you fancy. Food is a great joy.
