Celeb Chef Curtis Stone Says Double Big Mac Should Come with Health Warning

Celebrity chef Curtis Stone says foodies should be wary of McDonald's' new Double Big Mac ... and he thinks the mega burger should come with its own freakin' warning.

Curtis joined us Wednesday on "TMZ Live" to talk about the Golden Arches' super-sized creation, which Australians have been chowin' down on for a while, and is about to return to the U.S. for a limited engagement.

According to Curtis, this 4-patty beast is an eat-at-your-own-risk kind of situation, and should have a health warning attached to it ... but his concerns don't stop at the caloric intake -- which is around 740 calories, for the record.

Curtis thinks McDonald's has often provided a lack of food information to its customers -- namely the "100% beef," which could be a mixture of all kinds of meat cuts -- and folks should always know exactly what they're ingesting.

He also thinks companies like Mickey D's dominate the country by adhering to peoples' cravings, but Curtis tells us why that's doing a lot more harm than good.
