628 calories, 34 g fat (10.7 g saturated fat, 0 g trans fat), 1,078 mg sodium, 58 g carbs (4 g fiber, 12 g sugar), 25 g protein

At first glance, the Impossible Whopper seems like a good option. If you are not totally against plant-based meat and are craving a fast-food burger, this is certainly a fine option. But, when it comes to health, this burger is still high in sodium, fat, and carbs. On the bright side, it has the most amount of fiber out of all of the burgers on this list at 4 grams and is the only burger listed that doesn't contain trans fat.
