18 Vegetarian and Vegan Celebrities Who Make the Case for Meatless Monday

January 15th, 2018

If you are aware of the benefits of cutting out meat once a week in favor of three plant-based meals on Monday, you know that it doesn’t just improve your health – it does the environment a lot of favors as well. Meatless Monday is the perfect way to make your diet more plant-based and try out delicious recipes that put fruits, vegetables, and other sources of protein in the spotlight. But if you still need convincing, here are some familiar folks who can tell you how going meat-free has had a positive impact on their lives.

Kristen Bell

Bell has been a vegetarian since the age of 11 and went vegan until she found it “wasn’t sustainable” during her first pregnancy. She still doesn’t eat meat, and she chooses humanely produced dairy products.

Portman is an outspoken vegan who promotes the environmental impact on following a plant-based diet: “[W]e get to make decisions three times a day, what we do with our planet, and you can make a difference by even once a day or once a week choosing not to eat animals or animal products.” She’s expressed support for Meatless Monday, saying it “would make a huge impact” if everyone adopted it.

Vegan power couple! Cyrus and Hemsworth are both proudly vegan; Cyrus has two tattoos commemorating her commitment to a plant-based diet and Hemsworth was just named Australia’s sexiest vegan.

It only lasted 22 days, but Queen Bey and her husband famously went vegan a few years ago as a way to shed a few pounds. Twenty-two Meatless Mondays would be almost half a year, if you want to spread those meat-free days out!
