Olympic swimmer Adam Peaty said going vegan made him lose muscle.


Peaty, who swims for Great Britain, told UK news site Joe that he tried being vegan in 2018 but found it too hard to incorporate enough protein into his diet.


"It's hard to understand how much protein you need. For me, I need meat to get enough protein," Peaty, 26, said. "It's a hard diet to adjust to. It's just too hard with the amount of muscle I have to sustain."


The 6'3" tall swimmer consumes no more than 6,000 calories a day, and said he would eat more plant-based foods if he didn't train so hard.


"I'm a big guy so I do need a lot of protein," Peaty said. "Sometimes I will swap meat for a vegetarian option — I think it's important to branch out and explore different options."
