No Point In Having Sex

“In fact, having sex burns calories at about the same rate as walking at a pace of 2.5 mph. ‘Given that the average bout of sexual activity lasts about 6 minutes,’ the authors write, a man in his early to mid-30s might burn 21 calories. But wait, it gets worse: Considering that this man could burn 7 calories just watching TV, the true benefit of having sex is only 14 additional calories burned.”
 — Many common beliefs about dieting and exercise, such as the one about how sexual intercourse burns 300 calories, are not at all true. So go ahead and take the night off.
