If Zion Williamson wants to cut out injuries and cut weight ... he NEEDS to cut meat out of his diet ASAP, so says John Salley who says VEGANISM can save Zion's career.
Look, a lot of people think 284 pound Zion is just too heavy to have a long NBA career. He's already missing the first 6 to 8 weeks of the NBA season after undergoing knee surgery.
Enter Salley ... who says Zion can turn the ship around if he turns his diet around.
"My message to Zion? Go vegan, bro. Drink a bunch of water and find out the best way to heal your body, meaning ... not just ultrasounds, not just a hot tub, don't take pills."
The 4-time NBA champ says Zion was destined to become teammates with Jahlil Okafor, who recently made the switch to "mostly" veganism and lost 20 pounds ... and Salley wants Williamson to listen to the vet.
"Jahlil Okafor will put you on the whole path on losing that weight, getting your knee back in position and playing."
