Question: how many calories in burger king's new impossible whopper?
Answer: The answer is a little complicated. A traditional Whopper has 660 calories, 40 grams of fat (12 of which are saturated) and 28 grams of protein. The Impossible Whopper clocks in at 630 calories, 34 grams of fat (11 saturated) and 25 grams of protein, so it's pretty similar from a macro nutritional standpoint.
