Better than a slice of pizza

While there's a widely held belief that a half hour of energetic sex burns the equivalent calories in a slice of pizza, it's just not true.

Let's look at the math: A half hour of vigorous sex burns about 85 calories, and a slice of plain cheese pizza is about 230 calories, while a slice of pepperoni is about 290 calories. So, it's pretty clear that it takes more than 30 minutes of active lovemaking to burn off a single slice.
