An Angus Third Pounder burger is displayed at a McDonald's in Anaheim, Calif. The new sandwich, being test-marketed, contains between 720 calories to 860 calories, depending on the version. That compares to 740 calories for McDonald's double Quarter Pounder and 540 for the Big Mac.
McDonald’s is fattening up its menu, testing the concept of putting one-third of a pound of beef on a bun. It would be its biggest burger yet.
