Burger King is doing its part to help their customers eat healthier by offering them a less fatty option for French fries, called "Satisfries," USA Today reported.

In the raging war for fast food consumers' favorite fries, Burger King is looking to get a healthy edge on McDonald's and Wendy's by cutting down on fat and calories. The Satisfries will have 30 percent less fat and 20 percent fewer calories than Burger King's regular fries. They will also be 40 percent less fatty and have 30 percent less calories than McDonald's fries.

All BK locations in North America will begin selling the Satisfries Tuesday. The new fries will be sold alongside the regular ones and will cost 30 to 40 cents more, except in Kid's Meals, which will have no difference. The fries will look different as well, using an old-fashioned crinkle-cut.

BK said it is not changing the process, oil or potatoes used to make their regular fries in order to make Satisfries. The fast food company even said all of the ingredients will remain the same. The change lies in the configuration in the amount of ingredients that will absorb less oil with thinner batter. BK did not specify how the ingredients would be re-configured.

Customers will decide at the cash register or in the drive-thru if they want to spend a little extra for the newer, healthier option. If the Satisfries become popular enough, they could become the permanent French fry option.

"Small changes create a big impact," says Alex Macedo, president of Burger King North America. "This will grow, just like diet soda grew over time."

BK estimated one in two customers order fries, putting their total French fry sales at 56 million per month. The Satisfries could have an immediate impact if enough customers choose them.

"It's not realistic to ask people to replace french fries with carrots or celery sticks," says Keri Gans, a registered dietitian hired by Burger King. "This is like meeting people halfway."
