Go with whichever looks smaller. “A lot of hot dogs – are very, very high in fat, much more so than a char grilled burger,” Moloo says. However, at fast-food restaurants, the hot dogs tend to be smaller than the burger and contain fewer calories. For example, at Wieneschnitzel, a deluxe hamburger contains 400 calories and 4 grams of saturated fat; a deluxe hot dog contains the same amount of saturated fat but only 270 calories. Upgrade to polish sausage and you’re looking at 480 calories and 10 grams of saturated fat. An A&W burger contains 440 calories and 7 grams of saturated fat , whereas an A&W hot dog has 280 calories and 6 grams of saturated fat. One benefit of choosing the burger is you can load it with lettuce and tomato, not typical condiments for a hot dog.
