Hemsworth reportedly inherited the habits from younger brother Liam, who has been eating vegan for over three years now.

"There are no negatives to eating like this. I feel nothing but positive, mentally and physically. I love it. I feel like it also has a kind of domino effect on the rest of my life," explains the youngest Hemsworth brother.

With a rise in ‘vegan bodybuilding’, the benefits of a vegan lifestyle are becoming more apparent when it comes to athletic performance, especially with not one, but two Hemsworths as proof.

However the Hemworths’ new diet isn’t only helping them get into superhero shape, it has turned them into living breathing world-saving man-mountains, and they’re not alone. In fact, when Men's Health USA readers about going vegan on Twitter, nearly 20 percent of them said they'd at least give the diet a shot.

People are increasingly adopting vegan diets for health and ethical reasons, too. Plant-based products are in higher demand than ever and will continue to grow as a food trend in 2018, according to predictions from Whole Foods Market. And according to new research released today, removing meat and dairy from your diet is the quickest and most effective way of reducing your impact on the environment.

“A vegan diet is probably the single biggest way to reduce your impact on planet Earth, not just greenhouse gases, but global acidification, eutrophication, land use and water use,” said Joseph Poore, lead researcher on the project from University of Oxford, UK.

“It is far bigger than cutting down on your flights or buying an electric car.”

Leaving no stone unturned, the scientists pulled data from over 119 countries, representing 90 per cent of all the food eaten. The results, published in the journal Science, suggest that meat and dairy provide 18 per cent of total calories eaten worldwide, and 37 per cent of the total protein. However the livestock used to produce these products take up 83 per cent of total farmland. In a scary fact, 86 per cent of all land mammals are now lifestock or humans according to the research.

“Agriculture is a sector that spans all the multitude of environmental problems,” he said. “Really it is animal products that are responsible for so much of this. Avoiding consumption of animal products delivers far better environmental benefits than trying to purchase sustainable meat and dairy.”
