How does one slice of cheesecake have 490 calories... but 4 slices of the same cheesecake have 2250?

Either the 4 slices should have 1960 calories total, or the one slice should have 562 calories...

When calories reaches a critical mass, they just explode.

If four people eat only one piece each, it's 490 calories. If ONE person eats all four, BOOM.
