EXCLUSIVE
Two powerful obesity organizations are having a hard time stomaching Charles Barkley's offensive comments about fat women in San Antonio ... and now they're calling for Sir Charles to apologize.
He also said, "Victoria is definitely a secret [in San Antonio] ... they can't wear no Victoria's Secret down there."
The statements are not sitting well with the National Association to Advance Fat Acceptance which is now calling for Chuck to apologize, ASAP.
"Making slurs about body size is just as offensive as making comments about body color," spokesperson Peggy Howell tells TMZ Sports.
"One would think being a black man, he'd be more sensitive to having his physical body criticized. It's totally out of line. He should absolutely apologize."
The President of the Obesity Action Coalition has also issued a statement expressing "extreme disappointment" with Charles.
"As a former NBA player and sports entertainment figure, Mr. Barkley should encourage equality and respect among society and not look to shame or segment one population because of their size."
"Obesity is a serious medical condition and not a joking matter."
We reached out to Charles for comment -- so far, no word back.

Charles is offensive? Have you read your headline? "Fat groups?" That's not offensive? I'm sure "no one on your staff" wrote it.

Did she really just compare "body size" to skin color?

They need to shut their fat azzes up. Fat people are not only unhealthy but they look like crap

This is the same dude so outraged over Sterling's comments yet insults fat people. Love the hypocrisy of the P.C crowd. As long as they are not the targets of bashing it is o.k to bash others. I hope the fatties and women give this dude hell. By the way, Old Chuck doesn't look like he has missed too many meals. Before calling others fat he might look in the mirror.

Hey everyone, Lets get him fired and sued like all the other celebs that say something everyone doesnt agree with. Or people can just learn to brush things off they dont agree with

Charles, look in the mirror. Some people might not think you're great to look at either. You sound like a very insensitive guy!
