At 50, Isla Fisher told Balance magazine, “I don’t want to look younger, I just want to look OK for my age. Realizing that has made life a lot easier.”

Although she doesn't intend to look younger, Fisher still looks far younger, even at 50. So, what is her secret to maintaining a fit appearance and a healthy physique over the years?

The answer is Fisher’s diet, nutrition, and other fitness habits, like workouts, that have changed over the years and helped her maintain that glow and fitness.

According to a Popsugar article published in 2014, Fisher’s priorities shifted toward a vegetarian diet at that time, driven by her love for animals and her mindset as a mother.

However, to maintain her nutrient levels, she includes seafood, specifically fish, in her diet.

Fisher said, "I’m a partial pescatarian. I eat a lot of fish for omega-3(s). I can’t eat anything that breastfeeds.”

By 2017, her philosophy and fitness goals had changed, and she adopted the philosophy of foundational health habits and graceful aging over restrictive diets.

According to People, published in 2020, by that time, Fisher focused on food freedom, a healthy relationship with food for her daughters, and body acceptance. Fisher also admitted that she didn't have a scale.

Highlighting her past pregnancies and reflecting on the time when she dealt with severe morning sickness, Fisher embraced comfort foods that helped her manage nausea.

“I mostly ate supersized bowls of white pasta with loads of butter and cheese because that was the only thing that took away the nausea.”

In early 2025, she began exploring more therapeutic wellness. According to Newsweek, in the new era of her life, Fisher shifted toward integrated fasting and holistic care.

Speaking about her therapeutic wellness at a New Year's retreat at the Buchinger Wilhelmi clinic in Germany, she said:

"This has been the most incredible way to spend the new year. Therapeutic fasting, integrative medicine, inspiring treatments for the spirit and soul.”

Apart from diet and nutrition, Fisher’s workouts also played a vital role in her fitness.

She even rides a horse herself and exercises.

“She also partnered up with Nintendo for their Ring Fit Adventure last year, which is an adventure game that’s also a workout”.

Last but not least, Fisher is also a fan of swimming and snorkeling.
