Miley and Others Quit Eating Vegan. Expert Advice On How to Keep Going

Whether motivated by health, environmental, or ethical reasons, more and more people are choosing to adopt a partly plant-based or fully vegan diet. By one recent estimate, 5 percent of US consumers identify as vegan and 55 percent of Millennials self-identify as flexitarian. Anyone considering going plant-based has likely heard about the optimal performance benefits of avoiding meat and dairy, as athletes like Tom Brady, Novak Djokovic, Chris Paul, and Venus Williams choose to compete while eating a variety of plant-focused diets, from partly plant-based to strictly vegan.

The message that veganism is a sustainable, healthy lifestyle gets undermined when plant-based celebrities, such as Miley Cirus, decide to give up being vegan and go back to eating meat, as she did in 2020. Of course, everyone is entitled to eat whatever they want, but the issues that motivated these celebrities – such as Liam Hemsworth, Mike Tyson and others – to stop eating vegan could have been solved without adding animal products or fish back into their diets. It all comes down to planning, researching, and eating a wide range of plants.

Here is a closer look at some well-known celebrities who ended their vegan diet, and how they could have kept going, by finding the nutrients they needed from plant-based foods. The point isn't to coax them to eat a vegan diet, but to inform you and anyone else who reads their reasoning, to understand that when it comes to a healthy, well-balanced diet, there are plant-based options that allow for you to get all the nutrients your body needs.

After several years as an outspoken vegan, animal rights activist who cried after eating fish the one time that her then-husband grilled it for her, Miley Cyrus told fans she ditched her plant-based diet in 2020 in favor of pescetarianism (eating fish but not meat). Cyrus made the transition because she believed she was deficient in Omega-3 fatty acids. She explained that her “brain wasn’t functioning properly” in a 2020 interview on The Joe Rogan Experience.

Often called brain fog (or mild cognitive impairment) this state of lack of focus or memory lapse is common in older adults and can be caused by a myriad of issues, many of which are unrelated to diet. Lack of sleep, low blood sugar, or even COVID can all contribute to brain fog. So Cyrus’s attribution that her vegan diet was the sole cause of her brain fog could be off the mark.

There are 3 types of Omega 3s: ALA, EPA, and DHA. Fish are a rich source of the long-chain omega-3s DHA and EPA, which are beneficial for the brain, but so are algae oil supplements, which can provide a healthy dose of brain-boosting Omega-3s.

In addition, our bodies convert some of the short-chain omega-3 ALA from the food we eat into DHA and EPA, typically enough to maintain brain health and function. Excellent sources of ALA include flaxseed, chia seeds, walnuts, and brussels sprouts.

There may be some merit to Cyrus’s claim since not everyone is efficient at converting ALA into DHA and EPA, which are the active forms of Omega-3 your body needs. If she wasn’t eating enough foods high in ALA or couldn’t convert sufficient amounts into EPA/DHA (and wasn’t supplementing algae oil), she may have been low in omega-3s and experienced brain fog.

“ALA is the precursor to DHA and EPA, so it must go through a conversion process in the body. Unfortunately, this conversion process is not efficient in most people,” explains Ryan Andrews, MS, of Precision Nutrition. “The only way to get a consistently reliable amount of DHA and EPA on a plant-based diet would be through algae oil supplementation.”
Anne Hathaway gave up her vegan diet because of low energy.

Actor Anne Hathaway stopped eating vegan while filming the movie Interstellar due to the physical demands of wearing a bulky spacesuit every day, Hathaway revealed to Harper’s Bazaar back in 2014. Hathaway says she "just didn't feel good or healthy, not strong” during her time as a vegan and that after eating salmon her “brain felt like a computer rebooting.”

Our energy levels are related to what we eat, but a vegan diet can be planned out to include nutrients that give us energy, focus, and mental sharpness, says Jinan Banna, PhD, RD, a Registered Dietitian and associate professor at the University of Hawaii. Often times someone eating vegan can lack specific nutrients and minerals needed to provide cells with energy, she adds. “If you’re not getting enough of certain nutrients, such as iron, you may have low energy,” Banna explains

“Iron is needed to transport oxygen in the body, which is essential for energy.” Good plant-based sources of iron include lentils, chickpeas, beans, tofu, spinach, pumpkin seeds, raisins, and fortified cereals. When combined with vitamin C (abundant in many fruits and vegetables), iron absorption can increase by 67 percent.

Many people don’t realize that you may need to eat more food to get enough energy when switching to a vegan diet because plants are generally less calorically dense than animal products. Also, you need to eat more calories if you’re physically active, as many performers and athletes are. Calorie-dense plant-based foods include legumes, avocados, dates, and any type of nut butter.

To ensure you're getting enough calories, eat more healthy fats, Banna suggests. Fats are the most calorically dense macronutrient, containing nine calories per gram compared to carbs and protein which provide four calories per gram. “Add more avocado, nuts, nut butter, olive oil, and tahini to your diet for a calorie boost. Smoothies are another great option for getting more calories,” the RD advises.

Actor Liam Hemsworth scrapped his vegan diet in 2019 after getting kidney stones. “I was vegan for almost four years, and then [in] February of last year I was feeling lethargic. Then I got a kidney stone. It was one of the most painful weeks of my life,” Hemsworth told Men’s Health in 2020. Hemsworth suffered from a calcium-oxalate kidney stone, the most common type according to the National Kidney Foundation (NKF). Calcium-oxalate kidney stones are caused by too many oxalates in the urine, which can crystalize and form a solid "stone."

“Every morning I was having five handfuls of spinach, and then almond milk, almond butter, and also some vegan protein in a smoothie,” Hemsworth told Men’s Health at the time. Considering that some of the highest oxalate foods are spinach, almonds, beets, chard, and beans, it’s no wonder Hemsworth developed a kidney stone. “If you eat a lot of oxalate-rich foods like leafy greens or nuts – foods that might be more common in a vegan diet – you’re increasing your chance of getting kidney stones,” warns Dr. Koushik Shaw, MD, a urologist at the Austin Urology Institute.

It’s easy to blame a vegan diet as the source of Hemsworth’s kidney stone. After all, his diet did veer toward the extreme oxalate end of the spectrum. But a lack of variety in any diet can cause problems down the road. The fact that he ate plants exclusively without varying the choices means not getting a diverse spectrum of nutrients, and vitamins and building up a healthy microbiome – since the bacteria in your gut thrive on multiple types of foods, not the same food over and over again.

Eating five handfuls of spinach every day is pounding your kidneys with far too many oxalates. (And don’t forget his morning smoothie included almond butter and almond milk, two other high-oxalate sources.)

Hemsworth might have been able to avoid giving up a vegan approach if he had included more variety. For example, instead of spinach every day, swap it out for kale or bok choy — two low-oxalate, nutrient-dense greens. Replace the almond milk with oat milk or pea milk. Snack on walnuts or cashews instead of only almonds, or replace the almond butter with peanut or sunflower butter. Whenever you can, choose a variety to strengthen your overall health and immune system.

Lack of calcium in the diet can also contribute to the formation of kidney stones. Eating foods high in calcium is the best way for your kidneys to flush out oxalates and avoid forming stones because calcium binds with oxalates in the intestines before entering the kidneys, according to the NKF. Foods like kale, bok choy, broccoli, tofu, and fortified non-dairy milk are all excellent sources of calcium and also are low in oxalates.

To help keep kidney stones at bay, Dr. Shaw recommends you stay hydrated, don’t eat too much protein, consume less sodium, avoid vitamin C supplements, and include insoluble fiber in your diet.

Whether you’re a seasoned plant-based eater or new to ta vegan diet, do your research or speak with a dietitian who can help you plan a healthy, balanced vegan diet to ensure you’re getting all the nutrients you need including Omega-3s, calcium and iron.

The number one tennis player in the world, Novak Djokovic, went plant-based more than twelve years ago to enhance his athletic performance and win more matches. In recent interviews, he has credited going vegan with helping him rise from third place in the world to first in the world because it helped clear his allergies. Before changing his diet, Djokovic had searched for cures to the breathing issues that cost him matches and focus which caused him to struggled during his most intense matches. The allergies used to make him feel like he couldn’t breathe and would be forced to retire from competitive matches as he did in Australia. "Eating meat was hard on my digestion and that took a lot of essential energy that I need for my focus, for recovery, for the next training session, and for the next match," he said. Djokovic emphasized he does not eat foods that require a lot of digestion, especially in the morning, when he needs all of his energy for training. Instead, he starts the day with hot water and lemon, then celery juice, and some superfood supplements.

Tia Blanco won gold at the International Surfing Association Open in 2015 and credits her success to her vegan diet. Blanco reports that a vegan diet helps her stay strong and she enjoys eating different forms of vegan protein like nuts, seeds, beans, and legumes. The professional surfer was influenced by her mother, who is a vegetarian and grew up in a veggie-forward household, Blanco has never eaten meat in her life, which made the plant-based switch much easier. And speaking of making things easier, Blanco has an Instagram cooking page called @tiasvegankitchen where she shares her favorite simple vegan recipes so all of her fans can eat like their favorite professional vegan athlete. In addition to her home-cooked meals, Blanco recently became an ambassador for vegan company Beyond Meat and now she posts Instagram stories and highlights of her favorite meatless meat recipes.

Steph Davis has been vegan for 18 years now and says, "there’s nothing in my life that hasn’t become better as a result, from climbing and athletics to mental and spiritual well being." Davis has competed on some of the most challenging verticle routes on the planet –like Concepcion (5.13), which is known to be one of the hardest pure climbs anywhere. Davis holds the third overall ascent and is the first female to ever make the ascent of the route. Davis described it as her "most technically demanding climb ever." Davis explained why she went vegan eight years ago when she partnered with PETA. "What can we do to start making changes in a positive way? And if it just so happens that changing our lifestyle leads to environmental benefits, health benefits, economic benefits, and positive social change, then all the better. One thing I’ve learned is you don’t have to do or be anything you don’t want to be, and you can change anything in your life just by starting to do it. It’s you who chooses who and what you are, by the things you think and the things you do." She goes on to add, "no one says you have to become a “perfect” vegan overnight. But why not start making small changes and see how it feels? I believe it’s the small choices people make that have the biggest power to change, and nothing is more simple yet also more far-reaching than changing how and what you choose to eat. We’re all here for a short time, in the end, and living a well-intentioned and compassionate life seems like what ultimately matters the most, the only real goal that I aspire to."

Tennis champion Venus Williams swears that making the switch to veganism was one of the factors that helped to improve her performance and get over an auto-immune disease. The tennis star went vegan back in 2011 when she was diagnosed with Sjögren's syndrome, a debilitating autoimmune disease with a range of symptoms from joint pain to swelling, numbness, burning eyes, digestive problems, and fatigue. She chose to eat plant-based to recover to her formerly healthy self, and it worked so she stuck to it. The seven-time Grand Slam singles champion recovers faster on a plant-based diet now, compared to how she felt back when she ate animal protein. When you have an auto-immune disease you often feel extreme fatigue and random body aches and for Venus, a plant-based diet provides energy and helps her reduce inflammation. The Beet reported on Willaim's diet and what she normally eats in a day to stay healthy, fit, and win more matches. Talking about her favorite dinner meal, Williams adds, “sometimes a girl just needs a donut!"

Mike Tyson recently said he is "in the best shape ever" thanks to his vegan diet. The boxing legend then announced he's getting back into the rings after 15 years, to fight against Roy Jones, Jr. in California later this fall. Tyson went vegan ten years ago after dealing with health complications and in the wake of having cleaned up his life: “I was so congested from all the drugs and bad cocaine, I could hardly breathe." Tyson said, “I had high blood pressure, was almost dying, and had arthritis." Now, the 53-year-old powerhouse is sober, healthy, and fit. "Turning vegan helped me eliminate all those problems in my life,” and "I'm in the best shape ever." His new trainer agrees: Watching Iron Mike's speed during recent training sessions, observed: "He has the same power as a guy who is 21, 22-years old."

Oklahoma City's point guard Chris Paul decided to ditch meat and dairy and was asked join on as a co-executive producer for the popular documentary, The Game Changers. For breakfast, Paul enjoys oatmeal with plant-based milk and nut butter. For lunch, he fuels up with pasta or brown rice with Beyond Meat sausage, grilled vegetables, and a curry sauce. His chef told USA Today, "The main thing is, we try to keep it as light and clean as possible for his normal routine, with organic ingredients. Anything that can minimize body inflammation. Chris is always worrying about what he can and can't eat." So far it appears he's getting it right. In an exclusive interview with The Beet's Awesome Vegans columnist Elysabeth Alfano, Paul said eating a plant-based diet helps him keep up with players half his age.

In 2016, Kaepernick made the switch to veganism with his longtime girlfriend to recover from a series of injuries that had him down for the count. The Beet recently reported on how this dietary switch has allowed Kaepernick to stay strong and healthy. Now, he's in the gym building muscle and looks fitter than ever. But will he be picked up? The professional football player claims that a vegan diet makes him feel "always ready" to perform his best on the field.

Cam Newton just replaced Tom Brady, who also follows a mostly plant-based diet, as the New England Patriot's QB, after having made the plant-based switch back in March 2019. The NFL Star first decided to ditch meat and dairy to recover quicker from injuries when he learned that a plant-based diet is proven to help reduce inflammation. "I've seen such a remarkable change in the way my body responds to the food that I eat," Newton told PETA for his recent partnership for a new campaign called, "Built Like a Vegan," proving that you don't need to eat meat to be strong. Newton enjoys a meat-free burger on a pretzel bun, heavy on pickles and sauce. He adds: "People often ask, 'How do you get your protein?' I just say, 'I get it in the same way you do, but it's fresher and cleaner.' " Newton shares how to do it: "My advice to a person who wants to become vegan is to eat on schedule. If you can eat on a schedule, you won't miss [a meal or crave meat] or think anything different, and you'll be alright."

Elijah Hall says about his vegan diet: "Going vegan was the best decision" he has ever made. Hall holds records in the indoor 200 meters and was training for the Tokyo this summer when it got postponed by a year due to the pandemic. Hall said "the effects that it’s having on my body are amazing. Becoming a plant-based athlete has opened many doors to my health and my training." We predict he'll only get faster in the next 11 months and break records, come home with golf and be the world champion in 12 months.

Five-years ago, Morgan Mitchell went vegan and it made her faster, leaner and happier. Last year she was featured in the plant-based athletes documentary The Game Changers and said, “Being vegan has helped me immensely. I don’t feel sluggish like I did when I was eating meat, and my recovery from training really took off. It felt like an overall cleanse for my body, and I started seeing greater results on the track.” Now Michelle is committed for the planet as well. “Ultimately helping the environment and not contributing to animal cruelty was a big thing for me, too. That was my initial reason for going vegan, and the rest of the benefits were just added bonuses.” Mitchell describes what she eats in a day for enhanced performance and more energy to win sprints. “I like to make sure I have three different types of protein in there. I use tofu, beans, and mushrooms, along with spinach, vegan cheese, and hash browns,” she says. “I also love to add Beyond Meat for more flavor, which is a great source of plant protein as well. That usually keeps me full for the better part of the day," she told Well + Good.

"We were taught that eating animal products was good for us but we've been lied to for hundreds of years," said Lewis Hamilton. The Beet reported on Hamiltion's vegan diet quoting The New York Times that he credits his new plant-based diet with making the difference in his career. Hamilton gave up processed food and animal products for vegetables, fruit, nuts, grains, because of his strong compassion for animals, for the benefit of the environment, and his own health. Hamilton isn't the only vegan in his family. His dog Rocco is fully vegan and Hamilton says he's "super happy" on Rocco's very own IG post. Earlier this year, Hamilton gave up his private jet because he said it's a big pollutant and aims to live a sustainable lifestyle. Back in February, he started a line of sustainable clothing with Tommy Hilfiger at London Fashion Week.

Featured in The Game Changers for his elite strength and his superhuman ability to lift a car, Patrik Baboumiam is one of the strongest men in the world and also happens to be vegan. Baboumian lifted 358 pounds in the 2009 German log lift nationals. Back in 2014, Baboumiam partnered with PETA in his campaign "Want to be Stronger" describing powering yourself with plants and how you can build muscle without eating meat. One of his 2019 PETA campaigns showed him posing with crossed arms and leaves in his mouths with the text: "The world's strongest animals are plant-eaters: Gorillas, buffaloes, elephants and me." Bahoumiam's diet consists of a dairy-free shake for breakfast with 8 grams of protein and 0 carbohydrates. For lunch, he enjoys vegan sausage, falafel, low-fat oven fires, peppers, and more grilled veggies. He normally eats 250 grams of carbs and 90 grams of protein just for lunch. Dinner includes vegetables cooked potatoes, and tofu. If you want to eat like Boubanian, he reports his food diary on his blog BarBend.

Here's a guy who has worn many hats: Bodybuilder, Terminator, California Governor, and now vegan and advocate for the plant-based lifestyle. Arnold Schwarzenegger ditched meat and dairy and has proven that you don't need to eat animal products to be strong, healthy and reverse symptoms of heart disease. Now 73, he had a pulmonary valve replacement 1997 due to a congenital defect and underwent emergency open-heart surgery in 2018 to replace the valve again. He then changed his eating and fitness habits and now extolls the virtues of plant-based eating for the environment as well as health reasons. He is a producer of The Game Changers (a movie with many masters) and an advocate for going vegan for health, the environment and the sake of animals (he posts on IG with his pet donkey and miniature pony, both household dwelling animals). Schwarzenegger said last year: "Right now, seven million people are dying every year. That is alarming and everyone in the government has the responsibility to protect the people.... 28 percent of the greenhouse gasses come from eating meat and from raising cattle, so we can do a much better job."

Jurek is an extreme ultra-marathon runner who has won the Hardrock Hundred, the Badwater Ultramarathon, the Spartathlon, and the Western States 100 Mile Endurance Run (you get the idea). Jurek has been vegan for almost two decades, after easing into it by cutting out meat in college, he slowly stopping seafood and finally giving up all animal products once he realized that eating this way made him feel healthier and happier. To run such an extreme amount of miles, you need to fuel your body with plant-based foods that will give you enough energy and carbohydrates to go the distance. The goal is to eat 5,000-6,000 calories of plant-based foods daily. Jurek outlined his plant-based diet in an interview with Bon Appetite. Instead of waking up to a hot cup of coffee to boost energy, he prefers to drink tea and a green smoothie with spirulina or chlorella and a host of other ingredients. He adds bananas, frozen pineapple slices, or mangoes, brown rice and pea protein, (for protein) to rebuild what's lost in training. This is not just any smoothie.

Soccer star, Alex Morgan is one of the beloved members of the USA National Team that won the World Cup and has shown that the female players deserve to get equal pay as their male counterparts by the US Soccer Federation. She is also an animal rights advocate and longtime vegan, having given up meat when she decided that "it didn't feel fair to have a dog, and yet eat meat all the time,” referring to her adorable pup Blue. Morgan aims to eat 90 grams of plant-based protein daily to stay fit and lean, especially for her workouts and on the field. Morgan admitted that breakfast was difficult because "a lot of the things I love like pancakes and French toast had dairy and eggs." But now she enjoys oatmeal with nut butter and berries, smoothies, rice, quinoa, veggies, black beans, protein shakes, Mediterranean food, Impossible burgers, Mexican beans, and sauteed veggie burritos, she told USA Today.

Paul Rabil who played for the Boston Cannons and the New York Lizards of Major League Lacrosse, ditched meat and dairy after his 2019 season ended and revealed he's now "officially" vegan on YouTube. "At first [switching to a plant-based diet] was to help solve some pain and trauma that I was going through. Over the last two years, I've had two herniated discs.... and that has led to a ton of shooting pain down my legs, its called sciatica," Rabil explains the purpose of his diet switch. He adds: "I've tried to a lot of things; I've had a number of cortisone shots; I've done physical therapy for two years. And I reached a place where I was thinking 'okay maybe I can solve this with nutrition because a lot of our pain stems from inflammation. Within a few weeks, I started noticing a lot of alleviation so I started focusing and doubling down more on veganism"

Hannah Teter won Olympic gold and silver in the halfpipe and is also a seven-time XGames medalist. She changed her diet after watching the documentary, Earthlings when she discovered how "horrible" factory farming is. After a strict vegetarian diet, Teter liked the way she performed and believes that her diet helped her win gold at the 2006 games. She now considers herself "plant-based" and in an interview with the Huffington Post, Teter said, "I feel stronger than I’ve ever been, mentally, physically, and emotionally. My plant-based diet has opened up more doors to being an athlete. It’s a whole other level that I’m elevating to. I stopped eating animals about a year ago, and it’s a new life. I feel like a new person, a new athlete."

Djokovic is not the only tour player to go plant-based. Nick Kyrgios shared that he does not eat meat anymore because of his strong compassion for animals. During the time of the Australian wildfires, the Aussie native explained: "I've been passionate about animal welfare for some time now. I don't eat meat or dairy anymore. That’s not for my health, I just don’t believe in eating animals." "I tried a vegan diet a couple of years ago but with all the travel I do, it was hard to stick to it. Since then I've managed to make it work, and I've been vegetarian for quite a while. "Seeing the footage of these animals suffering from the fires only reinforces why I've chosen this diet. When I see these terrible photos, I can’t comprehend eating meat."

Matt Frazier has run 27 ultra-marathons in his career so far and continues to write about the endurance strength of being a vegan athlete in his personal blog, which he started 11 years ago: No Meat Athlete. The Beet recently interviewed Frazier about his vegan journey and how to be a successful athlete on a plant-based diet. When asked about the first time he ditched meat Frazier replied, "I had already cut 90 minutes off my first marathon time. I was still 10 minutes away from the Boston Marathon qualifying time. I had plateaued, and I was not sure how I was going to find 10 minutes. [Plant-based eating] was what I was missing. That’s what it took. The other big noticeable difference to me [after going vegan] was I stopped getting injured. Injuries had always been a big part of my running journey. When I became vegan, it was around the time I ran three 50-milers and a 100-miler. I didn’t have any injuries. If it’s done right, [plant-based diets] can really help you recover faster."

Rowing is grueling. It's known as the toughest endurance sport in the world. The world record-breaking female rower, Michaela Copenhaver went vegan in 2012 for ethical reasons, she told Great Vegan Athletes. “Initially, I just wanted to eat more vegetables. Those things are super good for you, and they're delicious. Being vegetarian and vegan made me more conscious of how many servings I was getting a day (or not).” When she switched from vegetarian to vegan it was almost accidental: “I was traveling for a regatta in the fall of 2012. I had been vegetarian for 1.5 years already but relied pretty heavily on dairy and eggs. While I was traveling, I was bouncing from couch to couch and had no way to safely store dairy or eggs—so I decided to try a week without them. I felt great, and it wasn’t nearly as scary as I thought. I’ve been vegan ever since.” Now it's a value system: “Once I stopped eating and using animals, I felt I could finally address a question that had been bothering me for a long time—what right do we have to exploit other creatures? Now, I understand that we have no right, and my motivations are primarily ethical.”
