Stupid calorie counter sites

I had an immense sweet craving yesterday and bought a small box of marzipan chocolates. After devouring the box, I felt guilty and thought I'd see how much it would account to. 170 grams of marzipan chocolates is roughly 726 calories.

My eyes fell to the writing under the nutritional information table.

"Try 170 grams of grapefruit instead?"
