McDonald's fries have always given Burger King heartburn - but watch out Ronald McDonald.
In a move destined to shake up the fast-food industry, Burger King Tuesday will unveil a simple but startling french fry innovation: french fries with 30% less fat and 20% fewer calories than BK's current fries. (And 40% less fat and 30% fewer calories than McDonald's fries.)
They've dubbed the new product Satisfries - not to replace BK's classic fries, but to be sold in addition to them. And they will be crinkle-cut, like old-fashioned fries.
The move comes at a time consumers are increasingly demanding healthier options - even in so-called junk food. The low-cal, low-fat fries will cost 20 cents to 30 cents more per serving (except in Kids Meals, where there will be no price difference). All Burger Kings in North America will begin selling them Tuesday.
