Like Liam Hemsworth, six other celebrities were formerly vegans and have spoken about their decision to swap it for diets that include animal products. From experiencing most dire situations like a health scare to doing it for "no real reason," this list is interesting.

1. Zooey Deschanel

The gorgeous actress says that she couldn't stick to veganism because of her many other food sensitivities. In a 2010 interview, she said:

"My older sister, ‘Bones' star Emily Deschanel, has been a very, very committed vegan since high school. I wish I could be like that, but I'm not. I have a lot of food sensitivities — I can't eat wheat or soy — and it was very difficult to eat and get enough calories. It was even impossible to eat at a vegan restaurant."

2. Derek Hough

Derek Hough only lasted for a few weeks when he tried a strictly vegan diet. The professional dancer says he first had it easy because he resided in Los Angeles. Although the diet seemed to come with several benefits, he had to give in to his meat cravings.

In a 2017 interview, he said:

"It was great, but I found for me if I'm craving something — like if I'm craving meat, then I'll have it. But I don't eat it as often, and I will say that. For me, it's about the greens … that gives you the energy."

3. Liam Hemsworth

The "The Hunger Games" star suffered a health complication following years of practicing veganism. He went under the knife in 2019 to remove a kidney stone, which doctors revealed developed because of his high consumption of oxalates, which can be found in popular vegan foods, like beans, spinach, and beetroot.

Although Hemsworth attests to the vegan diet's healthiness, the painful experience made him rethink his choice of diet.

He says:

"What I say to everyone is, ‘Look, you can read whatever you want to read. But you have to experience it for yourself. You have to figure out what works best for your body.'" 

4. Miley Cyrus

Miley Cyrus spent seven years following a plant-based diet but brought it to a halt because her "brain wasn't functioning properly."

This caused Cyrus, who had become a vegetarian because of her pets, to make the ultimate decision of introducing fish into her diet; thus, becoming a pescatarian.

5. Natalie Portman

Natalie Portman had a short break from veganism when she got pregnant in 2011. She explained:

"I actually went back to being non-vegetarian when I became pregnant, just because I felt like I wanted that stuff. I was listening to my body to have eggs and dairy."

However, Portman remains a passionate advocate for veganism, having revealed that she transitioned back to eating vegan after her pregnancy and that even her children now eat vegan.

6. Anne Hathaway

Anne Hathaway partially stopped being vegetarian because she "just didn't feel good or healthy, neither strong." This dawned on her after she was compelled to try a piece of salmon at an Iceland restaurant.

"I had a piece of salmon, and my brain felt like a computer rebooting," she said in 2018. 

7. Ellen DeGeneres

The famous TV show host boldly says she stopped being vegan "for no real reason." DeGeneres originally became a vegetarian for ethical reasons, and so she could "have energy."

However, in 2019, she disclosed that she only lasted eight years as a vegan. She said:

"I was healthier than I'd ever been. I loved being vegan. But just in the last year or two, for no reason really, I started eating a piece of fish once in a while. And I'll eat eggs from chickens I know — if they are in someone's backyard and they're wandering around, and they're happy."

On a final note, it is important to stress that everyone on this list managed to find what worked best for them and that is what is most important. No matter how good a diet, vegetarian or otherwise may seem, do a regular reassessment of its impact on your daily living.
