Martine McCutcheon Unveils Weight Loss Secrets at 50

She shot to fame as Tiffany Mitchell on and became a household name following her appearance in .

And more than two decades later,  has barely aged a day as she marked her 50th birthday on Thursday.

The actress announced her split from singer husband Jack McManus, 41, in October 2024 and 11 months later, .

In recent months Martine has been displaying her revenge body after prioritising her skin, diet and fitness following a turbulent year.

Martine has shared her health journey with fans on Instagram after dropping three dress sizes and five stone in weight.

In 2022, Martine revealed it has taken her 'such a long time to do what works for her' as she opened up about her health and staying in shape.

In an interview with OK! magazine, the Love Actually star noted that she didn't like to discuss her weight but told how she stays in shape by following the 80/20 rule diet.

Discussing her frame, Martine told how it hasn't always been straightforward in finding the right healthy eating lifestyle that works for her, with the star stating how important it is to just be the 'best version' of herself.

She said: 'I think it takes a long time to work out what your own recipe is. It's taken me such a long time to look through all the stuff that's out there, and do just what works for me. So it's not as simple as just going on a crazy diet. 

'I just feel it's really important to encourage women to just be the best version of themselves.'

Detailing her diet, she added: 'The 80/20 rule is what works for me. For 80% of my week, I will have mainly just healthy proteins, vegetables and fruit, organic and veggie juices, and Flora ProActiv spread. And then I'll have treats 20% of the time.'

She also makes sure to indulge a little, enjoying pizza, chocolate or a G&T for special occasions, noting that she doesn't feel guilty because she's doing 'good bits for my heart' for most of the week.

The mum-of-one also shared that she keeps in shape by walking her dogs everyday after the school run as well as Pilates, with the outings good for both 'my head and my health'. 

Martine, who made her children's TV debut as a teenager, has spoken previously about how growing up in the public eye made her aware of her weight from a young age. 

'I was always conscious of staying as thin as I could be,' she said in a 2016 interview. 'It looked better on camera, meant I could fit into size 8 sample sizes and it was easier and more affordable with stylists.'

When asked how many hurtful comments affected her, she admitted 'there were hundreds' and said she was body shamed 'loads of times'.

'People spoke about me like I was a piece of meat and I can’t believe that’s still going on in this day and age,' Martine added.

In 2003 her figure became the subject of national attention when her Love Actually character, Natalie, was teased for her weight.

She is called 'plumpy' by her father and referred to as 'chubby' by other characters. In the final moments of the film, the Prime Minister (Hugh Grant) says, 'God, you weigh a lot!' as he picks her up.'

The actress has defended the film in subsequent interviews, insisting it was supposed to help women see how they are perfect just as they are.

'Every woman thinks there’s something wrong with them when in actual fact... they are perfect and lovely as they are,' she said.

'[Natalie] was meant to be the embodiment of that and I think sometimes people have missed that point.'

Martine, who released a series of dance exercise videos a decade ago, has become a more regular presence on Instagram over the last year, making it easier for fans to see just how amazing she looks.

The star has been honest about how she uses Botox to maintain her youthful glow, posting a video in August of her most recent treatment.

In 2016, Martine spoke of how she's grown to love using Botox.

She detailed how she was left 'looking deranged' after her first ever session yet persevered and grew to love the facial enhancements.

She said: 'When I had a really tough time being unwell, it basically showed on my face a lot and I looked ravaged...

'I just looked in the mirror and thought I've always had nice skin, I always had a nice beautiful glow, and it has gone.

'So I had Botox and I didn't like it, it made me look a bit strange, and then I had it again, and Oh my god, I loved it, I absolutely loved it, because it didn't look like I wasn't me anymore, I just didn't look like me but not a creased pillow basically.'
