Diane Krugers Top Diet and Fitness Secrets at 50

proves age is nothing but a number as she continues to look younger than ever in her fifties.

The Hollywood actress celebrated her milestone 50th birthday surrounded by love and luxury in the heart of Venice on Wednesday.

In glamorous Instagram snaps, Diane was every inch the style icon as she roamed the Italian city in a chic gingham dress and white sunglasses.

The German movie star is widely known for her iconic roles in blockbuster films including Troy and National Treasure.

She first gained stardom on the runways in the nineties, modelling for the likes of Saint Laurent and .

Over three decades later, Diane has barely aged a day as she continues to maintain her remarkably youthful appearance.

Diane has said she's learning to 'embrace' the natural changes that come with age as well as the importance of self-love and acceptance.

The mother-of-one has adopted a positive approach to ageing through focusing on her health, diet and fitness.

As she marks another year older, what are the secrets to Diane's age-defying looks?

Diane, who shares daughter Nova Tennessee, seven, with her fiancé Norman Reedus, reconnected with her forgotten love of fitness after welcoming her child.

She wanted to regain control over her body to prepare for her role in spy film The 335 back in 2019. 

The movie is jam-packed with action sequences and stunts which Diane began training for just six months post partum. 

'It was daunting', she told Women's Health. 'But after six months of being a full-time mom, I was ready to get back to me, and to get out of the house. 

'It was fun to have a few hours away each day to focus on my body and my work. It was exhilarating to go back to working out - to lifting heavy, kicking higher, and trusting my body.' 

Boxing drills, running and two-hour training sessions soon became part of her weekly routine.

Her gruelling workouts include elliptical, burpees, box jumps, sit-ups, planks and 20-pound squats. 

As she has got older, Diane said she has learnt to love and appreciate her changing body and mind.

'I was naturally skinny when I was younger, and I did a lot of ballet and ballroom dancing, so I didn't work out traditionally. But by the time I hit about 32, I felt my metabolism change', she added. 'That's when I thought I needed to work out to be able to eat what I wanted - and I dreaded it.'

To combat tiredness, Diane started to take vegan multivitamins which she says helps her feel less depleted.

Diana makes sure she cooks a healthy meal from scratch every day for her fiancé and their daughter.

She told Grazia: 'We're healthy, I'm always trying to be rational about what I buy and what we need. I hate throwing away food.'

Diane previously detailed the secrets to her youthful looks, insisting she takes a natural approach to ageing.

'While I appreciate the benefits of skincare treatments like facials and massages, I prioritise practices that promote overall wellness and vitality', she told Women&Home.

'With age and motherhood, I've experienced a profound shift in my perception of myself,' Diane continued. 'Keeping fit, healthy, and strong for myself and my daughter is my main priority.

'I believe in everything in moderation, balance and enjoyment in my diet and fitness routine.'

Diane follows a protein-heavy breakfast, consisting of poached eggs, avocado and multigrain bread.

For lunch, she opts for a salmon-based meal with plenty of veggies and finishes with chicken or veal for dinner.
