"The Blind Side" star Quinton Aaron has been on an up-and-down battle with his weight, but right now he's up ... by being down 200 pounds.
Quinton tells TMZ, "At my heaviest, I was 575 pounds. As of today, I am 370 pounds."
What's even more incredible ... he did it all without Ozempic. Quinton says he tried the drug about a year ago because he's diabetic, but stopped after he had an allergic reaction.
