13 Celebrities Who Have Spoken About Following Vegan Diets

Plant-based living used to mean a limited menu and plenty of misconceptions, but celebrities have clearly rewritten the menu and the PR strategy.

Suddenly A-listers are trading steaks for chickpeas, and somehow still training hard, working long sets, and keeping busy schedules like nothing’s missing except the barbecue bill.

Turns out the biggest plot twist in Hollywood isn’t a surprise cameo, it’s vegetables stealing the spotlight and refusing to give it back.

1. Joaquin Phoenix

Joaquin Phoenix never outgrew a childhood vow. He has said a childhood experience watching fish being killed helped push his family toward veganism.

That moment shaped his entire life, turning him into one of Hollywood’s most passionate voices for animal rights.

Equal intensity drives both his activism and every role he takes on. Accepting an Oscar or speaking at a rally delivers the same clear message that compassion costs nothing.

2. Natalie Portman

One book reshaped Natalie Portman’s relationship with food during her college years. She has said she stopped eating meat as a child, and later credited Jonathan Safran Foer’s ‘Eating Animals’ with influencing her move away from eggs and dairy.

Several years later, another shift followed when she removed all animal products from her diet. Today, her kitchen centers on colorful produce and inventive plant based recipes.

The documentary adaption of “Eating Animals,” which examines the morality and effects of animal husbandry, was made by her.

3. Ariana Grande

Grande’s love for animals runs deeper than her love for high notes.

She has been publicly associated with vegan eating since at least 2013. Her social media posts often feature her rescue dogs and passionate pleas for animal welfare.

Touring the world on a plant-based diet sounds impossible, but she makes it look effortless. You don’t need steak to blow those whistle tones, as seen by her enthusiasm on stage.

4. Lewis Hamilton

Lewis Hamilton has said he moved to a plant-based lifestyle in 2017.

Racing at 200 miles per hour demands peak physical condition, and he discovered his competitive edge in vegetables rather than meat. A massive global platform now amplifies his conversations about climate change and factory farming.

At times, he has urged people to eat more plant-based foods.

5. Woody Harrelson

Persistent acne pushed Woody Harrelson toward an unexpected dietary change decades ago. After hearing a chat on the bus, he decided to stop eating dairy, which he later linked to feeling better.

That small adjustment grew into a complete lifestyle shift, and he has followed a plant based approach ever since.

Morning smoothies now pack in more greens than many salad bars, a habit he often jokes about.

6. Rooney Mara

Personal choices stay mostly private, yet Rooney Mara’s plate tells the story. For years, she has lived quietly as a vegan, allowing actions to speak louder than interviews ever could.

It has been widely reported that she supports animal welfare organizations and leads a completely vegan lifestyle.

Shared values connect her and her partner as they support animal sanctuaries and environmental causes together. Consistency becomes the loudest statement of all, proving a megaphone is never required to make a difference.

7. Alicia Silverstone

Silverstone wrote the book on plant-based parenting.

Literally. Among her publications on plant-based parenting and lifestyle are “The Kind Mama” and “The Kind Diet.”

Her son grew up on lentils and quinoa, thriving without a single chicken nugget. Public reaction has been mixed at times, but she has continued sharing her approach.

She’s living proof that compassion and nutrition can coexist beautifully.

8. Pamela Anderson

Activism shaped Pamela Anderson’s public life long before veganism entered the mainstream conversation.

Decades of advocacy placed animal rights at the center of her work, using fame to spotlight cruelty in laboratories and on farms. Daily diet mirrors those values without compromise.

She has taken part in high-profile animal-advocacy campaigns over the years.

One message remains constant as Anderson continues her advocacy: animals deserve better, and so does the planet shared by everyone.

9. Moby

Going vegan in 1987 placed Moby far ahead of a movement that had barely reached the mainstream.

Back then, finding plant milk often required trips to small specialty stores rather than everyday supermarkets.

Over the years, he has watched plant based living grow from fringe culture into a global trend, celebrating each new restaurant and product launch along the way. Success in music now helps fund activism, supporting animal sanctuaries and educational programs.

In Los Angeles, he launched the vegan eatery Little Pine in 2015; it closed in December 2022.

10. Evanna Lynch

Love for magical creatures on screen mirrors Evanna Lynch’s compassion for real animals off camera. After learning about the impact of animal agriculture, Lynch chose to adopt a vegan lifestyle.

“The ChickPeeps,” a vegan podcast on moral living, was co-hosted by her.

Gentle but steady messaging defines her approach, inviting curiosity rather than sounding preachy.

Belief in small changes guides her outlook, celebrating every person who swaps dairy milk for oat alternatives.

11. Jessica Chastain

Chastain has said a plant-based diet helps her feel better and keep her energy up for demanding work.

Cutting out animal products transformed her energy levels practically overnight. She woke up clearer, moved through her day lighter, and never looked back at her old habits.

Her demanding schedule requires serious stamina, from long shoot days to red carpet events. Plants fuel it all, proving that Hollywood glamour and ethical eating aren’t mutually exclusive in the slightest.

12. Billie Eilish

Outspoken views have become part of Billie Eilish’s public identity, spanning mental health, climate change, and animal rights.

For years, she has followed a vegan lifestyle while using her platform to question industries connected to animal suffering.

When she disclosed that she had emphasized a fur-free pledge associated with her Met Gala ensemble, it garnered international attention and sparked broader discussions about the hidden costs of design. Rather than preaching, she simply lives according to her beliefs with a voice that remains direct, confident, and unapologetic.

13. Cynthia Erivo

Cynthia Erivo’s powerhouse voice demands serious fuel. Plant-based eating became her answer after discovering her body performed better without animal products slowing her down.

From Broadway stages to Hollywood sets, carefully planned meals help maintain strength and endurance.

Personal choices reflect a broader commitment to wellness and sustainability. Food functions as medicine in her philosophy, with ingredients chosen to nourish her body and align beautifully with her values.
