Another day, another quizzical lifestyle suggestion from Tom Brady.

The Patriots quarterback, who released “The TB12 Method: How to Achieve a Lifetime of Sustained Peak Performance” on Tuesday, highlights his approaches to health and fitness, including the amount of water guzzled to protect his skin from the sun. Via SB Nation:

When I was growing up, and outside in the sun, I got sunburned a lot. … These days, even if I get an adequate amount of sun, I won’t get a sunburn, which I credit to the amount of water I drink. … When I once told that to my sister, she said, “You mean you don’t have to use all those moisturizers and facial products to keep my skin looking good? … I think you should market your TB12 Electrolytes as a beauty product.”

You should keep using SPF, though. Drink water, too, if you like, but keep using SPF.

Brady, 40, claims to drink between 12 and 25 bottles of water per day, complete with “TB12” electrolytes. Experts don’t encourage mere mortals to follow in the five-time Super Bowl champ’s footsteps.

“Twenty-five … is a lot. Very much a lot,” Alicia Roman, a clinical registered dietitian at the Tufts Medical Center, told the Boston Globe. “I would never recommend that to a patient.”

This isn’t the first time Brady’s intake has come under fire. After personal chef Allen Campbell broke down his diet, experts criticized the effects of the rigid regime.

He launched the $78-per-week, 100 percent plant-based, gluten-free meal plans earlier this year.
