Question: how unhealthy is a whopper?
Answer: The short answer: not very. Consider that Burger King's standard Whopper contains 660 calories, 12 grams of saturated fat, 11 grams of sugar and 980 milligrams of sodium. The Impossible Whopper contains just 30 fewer calories, 1 fewer gram of saturated fat, an extra gram of sugar, and 100 more milligrams of sodium.
