Halle Berry's 5 pillars of health to look and feel good, from keto to collagen to core workouts

• Halle Berry told Insider that focusing on wellness is the key to "realizing eternal beauty."
• There are five key pillars in her healthy lifestyle that keep her youthful, fit, and healthy.
• Berry, 54, always trains her core and makes time to meditate.

Halle Berry may be famed for her roles in films such as "X Men," "Die Another Day," and "Kingsman," but the actor is increasingly focusing on wellness.

In April 2020, the 54-year-old launched health and wellness platform Re-Spin.

"We wanted to be a part of the solution and address the needs of people who were interested in health, wellness, and fitness and who were committed to living their mindful, best lives," Berry told Insider.

The platform, she said, is "a place where we could hone in on our core pillars rooted in the belief that when you connect to yourself, nourish your soul, strengthen your body, awaken your mind, give back, you will realize eternal beauty."

Berry told Insider the five non-negotiables that keep her healthy, fit, and youthful.

1. Collagen

Berry told Insider her favorite supplement is "Collagen, collagen, and more collagen!"

With purported benefits for skin, hair, and nails, collagen is a staple for the actor. She mainly consumes it in the form of bone broth, either making her own from scratch using bones from a butcher, or with a powder.

2. The keto diet

Berry has followed the high-fat, low-carb keto diet for almost 30 years, she said.

The initial impetus was being diagnosed with diabetes aged 22. Berry says the diet helps her manage the condition, but she believes it also helps with anti-aging and weight loss.

3. Core workouts

"After having two children, my core is always the part of my body that I never leave out of my workouts," Berry said, adding that she uses her Re-Spin Full Body Resistance Loops to work her whole body including the core.

Even Berry struggled to workout from home during the coronavirus pandemic though.

"It was difficult finding the motivation in isolation, but at the same time it was more important than ever for mind, body, and soul to stay active," she said.

4. Meditation

Meditation has been "key" for Berry's mental health and holistic wellbeing.

"I try to do it as often as I can, even if it's only 20 minutes three times a week," she said, adding that she also tracks her sleep with an Amazon Halo and then adjusts her lifestyle based on the data.

5. Skincare

Berry keeps her complexion clear with a good skincare regime.

She always uses a vitamin C toner, face peel, sleeping mask, and the Flawless Cleanse brush.
