Fast-food giants McDonald's, Burger King, and Wendy's are all introducing new burgers or revamping existing menu items in an effort to compete for customer dollars. McDonald's has introduced its largest burger yet, the Big Arch Burger, which contains over 1,000 calories and is one of the most calorie-heavy burgers on the market. Burger King has also updated its most iconic item, the Whopper, for the first time in nearly a decade. Wendy's is focusing on smaller burgers and value items, while Burger King emphasizes smaller items. Some companies are betting that larger premium burgers will attract customers willing to pay more.
