Burger King wants you to try its new, lower-fat French fries for free.

The fast food chain is giving away the so-called "satisfries" Saturday and Sunday.

The freebie applies only to the value-sized fries, and there is a limit of one per customer.

Burger King said the "satisfries" have 30 percent less fat and 20 percent fewer calories that regular BK fries.

A small serving of "satisfries" has 270 calories and 11 grams of fat. Compare that with a small serving of classic fries, which has 340 calories and 15 grams of fat.
