But what about those growing waistlines? So far, fast-food firms have nimbly avoided government regulation. By providing healthy options, like salads and low-calorie sandwiches, they have at least given the impression of doing something about helping to fight obesity. These offerings are not necessarily loss-leaders, as they broaden the appeal of outlets to groups of diners that include some people who don’t want to eat a burger. But customers cannot be forced to order salads instead of fries.
In the future, simply offering a healthy option may not be good enough. “Every packaged-food and restaurant company I know is concerned about regulation right now,” says Mr Palmer of UBS.
In order to avoid more legislation on top of the just approved calorie posting in the US, fast-food companies will have to continue innovating.
