Liam Hemsworth Says He is No Longer Plant-Based After Developing Kidney Stones

If you've ever wondered which Hollywood stars follow a vegan or plant-based diet, a quick Google search will tout Liam Hemsworth as one of the top results. The actor has been vocal about the positive impact a plant-based diet had on his health as a whole, more specifically on his energy level and workouts.

Hemsworth started eating a plant-based diet back in 2015. He told Men's Health Magazine Australia the initial switch to a  vegan diet came after he fell ill with the flu while on a press tour for The Hunger Games. His co-star, who is also a longtime vegan, Woody Harrelson, suggested he eat more raw vegetables. Hemsworth took his advice and gave a plant-based diet a try.

In an interview with Men's Health, Hemsworth revealed he is no longer eating plant-based— for health reasons. He is on the latest cover of the Australian magazine discussing his change in diet and workout regiment.

"The first two years, I felt great,” he says. “I felt my energy was high. I felt like my body was strong, cardio was high, everything felt really good.”

However, that shifted last year, the 30-year-old adds:

"February last year I was feeling really low and lethargic and wasn’t feeling good generally," he said. This all led to Hemsworth being diagnosed with calcium oxalate stones, better known as kidney stones.

Famously Hemsworth and long-time vegan Miley Cyrus had a long-time on again off again relationship, brief marriage and vegan wedding, in which they served vegan spring rolls and touted the menu on their IG. Now that that marriage is long over and they have each moved on, it's natural to wonder if Hemsworth's new diet is tied as much to his new relationship status as his health.

Kidney stones are common, and occur in people with all types of diets, plant-based or not. Some oxalate-rich foods include dark greens, beans, coffee, beer and even animal protein can increase the risk of kidney stones.

"Consuming animal protein is associated with increased serum and urine uric acid in healthy individuals," the study concluded. "The stone-forming propensity is marginally higher for beef compared to fish or chicken. Stone formers should be advised to limit the intake of all animal proteins, including fish."

At the time of Hemsworth's diagnosis, he was eating an excessive amount of nuts, spinach and legumes, which are all high in oxalate. According to Men's Health, Hemsworth's morning smoothie had five handfuls of spinach, almond milk, almond butter and vegan protein. To put it into perspective, one cup of spinach has 200 milligrams of oxalates, which is the amount typically consumed in a single day.

Hemsworth acknowledged that while a plant-based diet wasn't working for him anymore, that isn't the case for everyone. His advice: “If something works for a period of time, great, keep doing it. If something changes and you’re not feeling great, then you’ve got to reassess it again and then figure it out.”

Eating plant-based itself wasn't the culprit to Hemsworth's health scare, but the lack of a balance in his diet could have contributed. An excess of any single food is never beneficial for your health. We love you Liam, but no one should put that much spinach in a smoothie.

Seven-time Grammy Award winner Carrie Underwood has been hailed for her “enormous” vocal range. When it comes to her diet, Underwood’s a fan of breakfast burritos and lots of tofu. She doesn’t shy away from the carbs, either. According to Cheat Sheet, one of her favorite snacks is a toasted English muffin with peanut butter.

Singer, songwriter, and “The Voice” coach, Blake Shelton, 43, has been working to stay fit recently with help from his long-time love, Gwen Stefani, who is a vegetarian and told him to get off the meat if he wants to feel fitter and lose some weight. Shelton has been trying to keep up with Stefani's impressive fitness level, according to an interview Stefani gave this fall. The former No Doubt singer and Hollaback girl is a longtime vegetarian, eats a mostly vegan diet, and is super fit-- and at 50, looks younger than her years. A source told Gossipcop, “Gwen’s told him the way to lose it is to stay the hell away from meat and bad carbs.” We're rooting for him!

The best-selling female country music singer in history isn’t buying any expensive steak dinners after a performance. The “Queen of Country Pop” has sold more than 100 million records but says she keeps her meat-free diet simple. She is both vegetarian and eats very little dairy -- though at times has said she does eat eggs.

Americana singer and songwriter Annette Conlon is also a passionate vegan. She started “The Compassionette Tour,” in an effort to bring compassion, social consciousness, human interaction, and animal issues to a mainstream audience.

The Man in Black is synonymous with country music, even nearly two decades after his death (1932-2003), probably in part because of the biopic about his life starring vegan actor Joaquin Phoenix. Ask any die-hard country music fan (or your dad, for that matter) and they will tell you that Johnny Cash was one of the best-selling musicians of all-time. His scores of hits include “I Walk the Line” and "Hurt" "A Boy Named Sue" and dozens of others. Cash himself was believed to have lived meat-free later in life to help combat some health issues. At Johnny Cash’s Kitchen and Saloon in Nashville, you can also load up on the meat-free dishes as the restaurant boasts a fully stacked veggie menu that includes greens, sweet potato mash, and fried okra.
