Award-winning British actress Jane Seymour hasn’t changed much over the years, especially when it comes to maintaining a healthy lifestyle.

While attending the SAG-AFTRA Foundation Conversations Presents Jane Seymour Career Retrospective event on May 20 in Los Angeles, the 74-year-old shared her dieting secrets that have kept her at a size 4 for decades.

“I love the Mediterranean way of eating, it works so well and it tastes good, it includes a lot of delicious food like tomatoes, olives and fish,” she told The Daily Mail.

“I start the day with coffee and hard boiled eggs for protein, and it isn’t until later, around lunch time, that I have a full meal because then I can really enjoy it.”

The “Dr. Quinn, Medicine Woman” alum limits herself to one big meal a day, but continues to fuel her body with protein filled nuts, seafood, and produce.

“I love fish and vegetables, and grow many greens in my back yard which I love to use,” she added.

The actress notes that the key to maintaining her healthy eating habits is viewing her diet as a lifestyle approach that focuses on overall food quality rather than quantity.

“If you think you are on a diet, you will lose track, you will cheat,” she explained. “But if you find healthy foods you really love, that make you feel good, you never feel shorted.”

Over the years, research has shown the benefits of eating a Mediterranean diet, which include maintaining healthy blood sugar levels, reducing chronic pain and inflammation, improving cardiovascular health, and more.

The Mediterranean way of eating focuses on a variety of whole grains, seafood, fresh fruits and vegetables, and healthy fats like extra virgin olive or avocado oil.

Working in the entertainment industry, Seymour understands the pressure to look a certain way and in the past has spoken out about how she focuses on health and wellness instead of turning to plastic surgery.

“I don’t do all that stuff everyone else is doing,” she told Fox News back in 2024. “I’m an actress. I need to be able to play 85 one day and younger another day.”

“Skin care is really important, I think the way I eat—I eat good Mediterranean food. Take vitamins. I exercise a little bit,” she continued.

“So, anything that I can do to, you know, keep myself fit and healthy and be able to play all the characters I play.”
